IMA AI Creation

⚙️ How This Skill Works

For transparency: This skill uses a bundled Python script (scripts/ima_create.py) to call the IMA Open API. The script:

  • Sends your prompt to two IMA-owned domains (see "Network Endpoints" below)
  • Uses --user-id only locally as a key for storing your model preferences
  • Returns image/video/music URLs when generation is complete

What gets sent to IMA servers:

  • ✅ Your prompt/description (image/video/music)
  • ✅ Model selection (SeeDream/Wan/Suno/etc.)
  • ✅ Generation parameters (size, duration, style, etc.)
  • ❌ NO API key in prompts (key is used for authentication only)
  • ❌ NO user_id (it's only used locally)

What's stored locally:

  • ~/.openclaw/memory/ima_prefs.json - Your model preferences (< 1 KB)
  • ~/.openclaw/logs/ima_skills/ - Generation logs (auto-deleted after 7 days)
  • See SECURITY.md for complete privacy policy

🌐 Network Endpoints Used

Domain Owner Purpose Data Sent Privacy
api.imastudio.com IMA Studio Main API (product list, task creation, task polling) Prompts, model IDs, generation params, your API key Standard HTTPS, data processed for AI generation
imapi.liveme.com IMA Studio Image/Video upload service (presigned URL generation) Your API key, file metadata (MIME type, extension) Standard HTTPS, used for image/video tasks only
*.aliyuncs.com, *.esxscloud.com Alibaba Cloud (OSS) Image/video storage (file upload, CDN delivery) Raw image/video bytes (via presigned URL, NO API key) IMA-managed OSS buckets, presigned URLs expire after 7 days

Key Points:

  • Music tasks (text_to_music) only use api.imastudio.com.
  • Image/video tasks require imapi.liveme.com to obtain presigned URLs for uploading input images.
  • Your API key is sent to both api.imastudio.com and imapi.liveme.com (both owned by IMA Studio).
  • Verify network calls: tcpdump -i any -n 'host api.imastudio.com or host imapi.liveme.com' (see SECURITY.md).

⚠️ Credential Security Notice

Your API key is sent to both IMA-owned domains:

  1. Authorization: Bearer ima_xxx...api.imastudio.com (main API)
  2. Query param appUid=ima_xxx...imapi.liveme.com (upload service)

Security best practices:

  • 🧪 Use test keys for experiments: Generate a separate API key for testing.
  • 🔍 Monitor usage: Check https://imastudio.com/dashboard for unauthorized activity.
  • ⏱️ Rotate keys: Regenerate your API key periodically (monthly recommended).
  • 📊 Review logs: Check ~/.openclaw/logs/ima_skills/ for unexpected API calls.

Why two domains? IMA Studio uses a microservices architecture:

  • api.imastudio.com: Core AI generation API
  • imapi.liveme.com: Specialized image/video upload service (shared infrastructure)

Both domains are operated by IMA Studio. The same API key grants access to both services.

Agent Execution (Internal Reference)

Note for users: You can review the script source at scripts/ima_create.py anytime.
The agent uses this script to simplify API calls. Music tasks use only api.imastudio.com, while image/video tasks also call imapi.liveme.com for file uploads (see "Network Endpoints" above).

Use the bundled script internally for all task types — it ensures correct parameter construction:

# ─── Image Generation ──────────────────────────────────────────────────────────

The script outputs JSON with url, model_name, credit — use these values in the UX protocol messages below. The script internals (product list query, parameter construction, polling) are invisible to users.


Overview

Call IMA Open API to create AI-generated content. All endpoints require an ima_* API key. The core flow is: query products → create task → poll until done.


🔒 Security & Transparency Policy

This skill is community-maintained and open for inspection.

✅ What Users CAN Do

Full transparency:

  • Review all source code: Check scripts/ima_create.py and ima_logger.py anytime
  • Verify network calls: Music tasks use api.imastudio.com only; image/video tasks also use imapi.liveme.com (see "Network Endpoints" section)
  • Inspect local data: View ~/.openclaw/memory/ima_prefs.json and log files
  • Control privacy: Delete preferences/logs anytime, or disable file writes (see below)

Configuration allowed:

  • Set API key in environment or agent config:
    • Environment variable: export IMA_API_KEY=ima_your_key_here
    • OpenClaw/MCP config: Add IMA_API_KEY to agent's environment configuration
    • Get your key at: https://imastudio.com
  • Use scoped/test keys: Test with limited API keys, rotate after testing
  • Disable file writes: Make prefs/logs read-only or symlink to /dev/null

Data control:

  • View stored data: cat ~/.openclaw/memory/ima_prefs.json
  • Delete preferences: rm ~/.openclaw/memory/ima_prefs.json (resets to defaults)
  • Delete logs: rm -rf ~/.openclaw/logs/ima_skills/ (auto-cleanup after 7 days anyway)
  • Review security: See SECURITY.md for complete privacy policy

⚠️ Advanced Users: Fork & Modify

If you need to modify this skill for your use case:

  1. Fork the repository (don't modify the original)
  2. Update your fork with your changes
  3. Test thoroughly with limited API keys
  4. Document your changes for troubleshooting

Note: Modified skills may break API compatibility or introduce security issues. Official support only covers the unmodified version.

❌ What to AVOID (Security Risks)

Actions that could compromise security:

  • ❌ Sharing API keys publicly or in skill files
  • ❌ Modifying API endpoints to unknown servers
  • ❌ Disabling SSL/TLS certificate verification
  • ❌ Logging sensitive user data (prompts, IDs, etc.)
  • ❌ Bypassing authentication or billing mechanisms

Why this matters:

  1. API Compatibility: Skill logic aligns with IMA Open API schema
  2. Security: Malicious modifications could leak credentials or bypass billing
  3. Support: Modified skills may not be supported
  4. Community: Breaking changes affect all users

📋 Privacy & Data Handling Summary

What this skill does with your data:

Data Type Sent to IMA? Stored Locally? User Control
Prompts (image/video/music) ✅ Yes (required for generation) ❌ No None (required)
API key ✅ Yes (authentication header) ❌ No Set via env var
user_id (optional CLI arg) Never (local preference key only) ✅ Yes (as prefs file key) Change --user-id value
Model preferences ❌ No ✅ Yes (~/.openclaw) Delete anytime
Generation logs ❌ No ✅ Yes (~/.openclaw) Auto-cleanup 7 days

Privacy recommendations:

  1. Use test/scoped API keys for initial testing
  2. Note: --user-id is never sent to IMA servers - it's only used locally as a key for storing preferences in ~/.openclaw/memory/ima_prefs.json
  3. Review source code at scripts/ima_create.py to verify network calls (search for create_task function)
  4. Rotate API keys after testing or if compromised

🧠 User Preference Memory

User preferences override recommended defaults across ALL task types.
If a user has generated before, use their preferred model — not the system default.

Storage: ~/.openclaw/memory/ima_prefs.json

Single file, shared across all IMA skills:

{
  "user_{user_id}": {
    "text_to_image":             { "model_id": "doubao-seedream-4.5", "model_name": "SeeDream 4.5",    "credit": 5,  "last_used": "2026-02-27T03:07:27Z" },
    "image_to_image":            { "model_id": "doubao-seedream-4.5", "model_name": "SeeDream 4.5",    "credit": 5,  "last_used": "2026-02-27T03:07:27Z" },

  }
}

If the file or key doesn't exist, fall back to the ⭐ Recommended Defaults below.


Model Selection Priority (Strict Order)

1. User explicitly specifies a model in this message
      → use it, save as new preference, confirm if different from old preference
2. User has a saved preference for this task type
      → use it, mention "根据你的使用习惯"
3. No preference exists
      → use ⭐ Recommended Default, save after success

When to Read (Before Every Generation)

import json, os

prefs_path = os.path.expanduser("~/.openclaw/memory/ima_prefs.json")
try:
    with open(prefs_path) as f:
        prefs = json.load(f)
    user_pref = prefs.get(f"user_{user_id}", {}).get(task_type)
except (FileNotFoundError, json.JSONDecodeError):
    user_pref = None

if user_pref:
    model_id   = user_pref["model_id"]
    model_name = user_pref["model_name"]
    credit     = user_pref["credit"]
    source     = "preference"   # pre-generation message: "根据你的使用习惯"
else:
    model_id, model_name, credit = RECOMMENDED_DEFAULTS[task_type]
    source = "default"

When to Write (After Every Successful Generation)

os.makedirs(os.path.dirname(prefs_path), exist_ok=True)
try:
    with open(prefs_path) as f:
        prefs = json.load(f)
except (FileNotFoundError, json.JSONDecodeError):
    prefs = {}

from datetime import datetime, timezone
prefs.setdefault(f"user_{user_id}", {})[task_type] = {
    "model_id":   model_id,
    "model_name": model_name,
    "credit":     credit,
    "last_used":  datetime.now(timezone.utc).isoformat(),
}
with open(prefs_path, "w") as f:
    json.dump(prefs, f, ensure_ascii=False, indent=2)

When to Update (User Explicitly Changes Model)

User Says Action
用XXX / 换成XXX / 改用XXX / use XXX Use that model this time AND save as new preference
以后都用XXX / 默认用XXX / always use XXX Save preference + confirm: ✅ 已记住!以后 [类型] 生成默认用 [XXX]
换个模型 / try another model Show top 3 alternatives, let user pick; save chosen
用最好的 / best quality Use highest-quality model for this type; save preference
用便宜的 / cheapest Use lowest-cost model; only save if user adds "以后都用"
清除我的偏好 / reset preference Delete user_{user_id}.{task_type} from prefs file; confirm

Pre-Generation Notification (with preference)

When using a saved preference, mention it naturally:

🎨 根据你的使用习惯,将用 [Model Name] 帮你生成…
• 模型:[Model Name](你的常用模型)
• 预计耗时:[X ~ Y 秒]
• 消耗积分:[N pts]

Preference Change Confirmation

When user switches to a different model than their saved preference:

💡 你之前喜欢用 [Old Model],这次换成了 [New Model]。
要把 [New Model] 设为以后的默认吗?
回复「是」保存 / 回复「否」仅本次使用

⭐ Recommended Defaults

These are fallback defaults — only used when no user preference exists.
Always default to the newest and most popular model. Do NOT default to the cheapest.

All other image models mentioned in older documentation are no longer available in production.

🌟 Parameter Support Notes (All Task Types):

Image Models (text_to_image / image_to_image)

  • aspect_ratio: NOT supported by any production image model (all produce 1:1 or fixed aspect ratio only)
  • size:
    • Nano Banana2: 512px, 1K, 2K, 4K (via different attribute_ids, 4-13 pts)
    • Nano Banana Pro: 1K, 2K, 4K (via different attribute_ids, 10-18 pts)
    • SeeDream 4.5: Adaptive default only (no size control, 5 pts)
  • 8K: No model supports 8K (max is 4K via Nano Banana Pro)
  • Custom aspect ratios (7:3, 4:5, etc.): Not supported. Use video models as workaround.
  • n: Multiple outputs supported (1-4), credit × n

Video Models (text_to_video / image_to_video / first_last_frame / reference_image)

  • resolution: 540P, 720P, 1080P, 2K, 4K (model-dependent, higher res = higher cost)
  • aspect_ratio: 16:9, 9:16, 1:1, 4:3 (model-dependent, check form_config)
  • duration: 4s, 5s, 10s, 15s (model-dependent, longer = higher cost)
  • ⚠️ generate_audio: Supported by Veo 3.1, Kling O1, Hailuo (check form_config)
  • prompt_extend: AI-powered prompt enhancement (most models support)
  • negative_prompt: Content exclusion (most models support)
  • shot_type: Single/multi-shot control (model-dependent)
  • seed: Reproducibility control (most models support, -1 = random)
  • n: Multiple outputs (1-4), credit × n

Music Models (text_to_music)

  • custom_mode: Suno only (enables vocal_gender, lyrics support)
  • vocal_gender: Suno only (male/female/mixed, requires custom_mode=True)
  • lyrics: Suno only (custom lyrics support, requires custom_mode=True)
  • duration: Fixed-length output (DouBao ~30s, Suno ~2min, not user-controllable)
  • n: Multiple outputs supported (1-2), credit × n

Common Parameter Patterns

  • n (batch generation): Supported by ALL models. Cost = base_credit × n. Creates n independent resources.
  • seed: Supported by most models (-1 = random, >0 = reproducible results)
  • prompt_extend: AI-powered prompt enhancement (video models only)

Decision Tree: When User Requests Unsupported Features

User asks for custom aspect ratio image (e.g. "7:3 landscape")
  → ❌ Image models don't support custom ratios
  → ✅ Solution: "图片模型不支持自定义比例。建议用视频模型(Wan 2.6 t2v)生成16:9视频,然后截取首帧作为图片。"

User asks for 8K image
  → ❌ No model supports 8K
  → ✅ Solution: "当前最高支持4K分辨率(Nano Banana Pro,18积分)。要使用吗?"

User asks for video with audio
  → Check model: Veo 3.1 / Kling O1 / Hailuo have generate_audio
  → ✅ Solution: "Veo 3.1 和 Kling O1 支持音频生成(需在参数中设置 generate_audio=True)。要用哪个?"

User asks for long music (e.g. "5 minute track")
  → ❌ Duration not user-controllable
  → ✅ Solution: "Suno 生成约2分钟音乐。需要更长时长可以生成多段后拼接。"

User asks for 30s video
  → Check model: Most models max 15s
  → ✅ Solution: "当前最长15秒。可选模型:Wan 2.6(15s, 75积分), Kling O1(10s, 96积分)。"

When user requests unsupported combinations:

  • Any image model + custom aspect_ratio → "不支持自定义比例,建议用视频模型(Wan 2.6)生成后截取首帧"
  • Any model + 8K → "最高支持4K (Nano Banana Pro, 18 pts)"
  • Image model + 7:3 → "图片模型不支持,建议用 Wan 2.6 视频模型(支持16:9/9:16)生成后截帧"
  • Video + audio (unsupported model) → "该模型不支持音频。建议用 Veo 3.1 或 Kling O1 (支持 generate_audio 参数)"
  • Music + custom duration → "音乐时长由模型固定(Suno约2分钟,DouBao约30秒),无法自定义"

estimated_max_seconds = upper bound of the range (e.g. 60 for SeeDream 4.5, 40 for Nano Banana2, 120 for Nano Banana Pro, 180 for Kling 2.6, 360 for Kling O1).


Step 1 — Pre-Generation Notification

Before calling the create API, immediately send:

[Emoji] 开始生成 [内容类型],请稍候…
• 模型:[Model Name]
• 预计耗时:[X ~ Y 秒]
• 消耗积分:[N pts]

Emoji by content type:

  • 图片 → 🎨
  • 视频 → 🎬(加注:视频生成需要较长时间,我会定时汇报进度)
  • 音乐 → 🎵

Cost transparency (new requirement):

  • Always show credit cost with model tier context
  • For expensive models (>50 pts), offer cheaper alternative proactively
  • Examples:
    • Balanced (default): "使用 Wan 2.6(25 积分,最新 Wan)"
    • Premium (user explicit): "使用高端模型 Kling O1(48-120 积分),质量最佳"
    • Premium (auto-selected): "使用 Wan 2.6(25 积分)。若需更高质量可选 Kling O1(48 积分起)"
    • Budget (user asked): "使用 Vidu Q2(5 积分,最省钱)"

Adapt language to match the user (Chinese / English). For video, always add a note that it takes longer. For expensive models, always mention cheaper alternatives unless user explicitly requested premium.


Step 2 — Progress Updates

Poll the task detail API every [Poll Every] seconds per the table.
Send a progress update every [Send Progress Every] seconds.

⏳ 正在生成中… [P]%
已等待 [elapsed]s,预计最长 [max]s

Progress formula:

P = min(95, floor(elapsed_seconds / estimated_max_seconds * 100))
  • Cap at 95% — never reach 100% until the API confirms success
  • If elapsed > estimated_max: freeze at 95%, append 「快了,稍等一下…」
  • For video with max=360s: at 120s → 33%, at 250s → 69%, at 400s → 95% (frozen)

Step 3 — Success Notification

When task status = success, send:

✅ [内容类型]生成成功!
• 模型:[Model Name]
• 耗时:预计 [X~Y]s,实际 [actual]s
• 消耗积分:[N pts]

[结果链接]

Step 4 — Failure Notification

When task status = failed or any API/network error, send:

❌ [内容类型]生成失败
• 原因:[natural_language_error_message]
• 建议改用:
  - [Alt Model 1]([特点],[N pts])
  - [Alt Model 2]([特点],[N pts])

需要我帮你用其他模型重试吗?

⚠️ CRITICAL: Error Message Translation

NEVER show technical error messages to users. Always translate API errors into natural language:

Technical Error ❌ Never Say ✅ Say Instead (Chinese) ✅ Say Instead (English)
"Invalid product attribute" / "Insufficient points" Invalid product attribute 生成参数配置异常,请稍后重试 Configuration error, please try again later
Error 6006 (credit mismatch) Error 6006 积分计算异常,系统正在修复 Points calculation error, system is fixing
Error 6010 (attribute_id mismatch) Attribute ID does not match 模型参数不匹配,请尝试其他模型 Model parameters incompatible, try another model
error 400 (bad request) error 400 / Bad request 请求参数有误,请稍后重试 Invalid request parameters, please try again
resource_status == 2 Resource status 2 / Failed 生成过程遇到问题,建议换个模型试试 Generation failed, please try another model
status == "failed" (no details) Task failed 这次生成没成功,要不换个模型试试? Generation unsuccessful, try a different model?
timeout Task timed out / Timeout error 生成时间过长已超时,建议用更快的模型 Generation took too long, try a faster model
Network error / Connection refused Connection refused / Network error 网络连接不稳定,请检查网络后重试 Network connection unstable, check network and retry
API key invalid Invalid API key / 401 Unauthorized API 密钥无效,请联系管理员 API key invalid, contact administrator
Rate limit exceeded 429 Too Many Requests / Rate limit 请求过于频繁,请稍等片刻再试 Too many requests, please wait a moment
Prompt moderation (Sora only) Content policy violation 提示词包含敏感内容,请修改后重试 Prompt contains restricted content, please modify
Model unavailable Model not available / 503 Service Unavailable 当前模型暂时不可用,建议换个模型 Model temporarily unavailable, try another model

Generic fallback (when error is unknown):

  • Chinese: 生成过程遇到问题,请稍后重试或换个模型试试
  • English: Generation encountered an issue, please try again or use another model

Best Practices:

  1. Focus on user action: Tell users what to do next, not what went wrong technically
  2. Be reassuring: Use phrases like "建议换个模型试试" instead of "失败了"
  3. Avoid blame: Never say "你的提示词有问题" → say "提示词需要调整一下"
  4. Provide alternatives: Always suggest 1-2 alternative models in the failure message

Always call GET /open/v1/product/list?category=<type> first to get the live attribute_id and form_config defaults required for task creation.

There are two equivalent route systems serving the same backend logic:

Route Auth Use Case
/open/v1/ Authorization: Bearer ima_* only Third-party / agent access
/api/v3/ Token + API Key (dual auth) Frontend App

This skill documents the /open/v1/ Open API. All business logic (credit validation, N-flattening, risk control) runs identically on both paths.

Environment

Base URL: https://api.imastudio.com

Required/recommended headers for all /open/v1/ endpoints:

Header Required Value Notes
Authorization Bearer ima_your_api_key_here API key authentication
x-app-source ima_skills Fixed value — identifies skill-originated requests
x_app_language recommended en / zh Product label language; defaults to en if omitted
Authorization: Bearer ima_your_api_key_here
x-app-source: ima_skills
x_app_language: en

📤 When to Upload Images (Quick Reference)

The IMA Open API does NOT accept raw bytes or base64 images. All image inputs must be public HTTPS URLs.

Task Type Input Required? Upload Before Create? Notes
text_to_image ❌ No Prompt only
image_to_image ✅ Yes (1 image) ✅ Upload first Single input image
text_to_video ❌ No Prompt only
image_to_video ✅ Yes (1 image) ✅ Upload first Single input image
first_last_frame_to_video ✅ Yes (2 images) ✅ Upload first First + last frame
reference_image_to_video ✅ Yes (1+ images) ✅ Upload first Reference image(s)
text_to_music ❌ No Prompt only

Upload flow:

  1. User provides local file path or bytes → call prepare_image_url() (see section below)
  2. User provides HTTPS URL → use directly, no upload needed
  3. Use the returned CDN URL (fdl) as the value for input_images / src_img_url

Example workflow (image_to_image):

# User provides local file
image_url = prepare_image_url("/path/to/photo.jpg", api_key)
# → Returns: https://ima-ga.esxscloud.com/webAgent/privite/2026/02/27/..._uuid.jpeg

# Then create task with this URL
create_task(
    task_type="image_to_image",
    input_images=[image_url],  # Use uploaded URL
    prompt="turn into oil painting"
)

⚠️ MANDATORY: Always Query Product List First

CRITICAL: You MUST call /open/v1/product/list BEFORE creating any task.
The attribute_id field is REQUIRED in the create request. If it is 0 or missing, you get:
"Invalid product attribute""Insufficient points" → task fails completely.
NEVER construct a create request from the model table alone. Always fetch the product first.

How to get attribute_id (all task types)

# Query product list with the correct category
GET /open/v1/product/list?app=ima&platform=web&category=<task_type>
# task_type: text_to_image | image_to_image | text_to_video | image_to_video |
#            first_last_frame_to_video | reference_image_to_video | text_to_music

# Walk the V2 tree to find your target model (type=3 leaf nodes only)
for group in response["data"]:
    for version in group.get("children", []):
        if version["type"] == "3" and version["model_id"] == target_model_id:
            attribute_id  = version["credit_rules"][0]["attribute_id"]
            credit        = version["credit_rules"][0]["points"]
            model_version = version["id"]    # = version_id / model_version
            model_name    = version["name"]
            form_defaults = {f["field"]: f["value"] for f in version["form_config"]}
            break

Quick Reference: Known attribute_ids

Pre-queried values for convenience. Always call the product list at runtime for accuracy.

⚠️ Production warning: attribute_id and credit values change frequently in production. Always call /open/v1/product/list at runtime; above table is pre-queried reference only (2026-02-27).

Common Mistakes (and resulting errors)

Mistake Error
attribute_id is 0 or missing "Invalid product attribute" + "Insufficient points"
attribute_id outdated (production changed) Same errors; always query product list first
attribute_id doesn't match parameter combination Error 6010: "Attribute ID does not match the calculated rule"
prompt at outer parameters[] level Prompt ignored; wrong routing
cast missing from inner parameters.parameters Billing validation failure
credit value wrong or missing Error 6006
model_name / model_version missing Wrong backend routing
Skipped product list, used table values directly All of the above

⚠️ Critical for Google Veo 3.1 and multi-rule models:

Models like Google Veo 3.1 have multiple credit_rules, each with a different attribute_id for different parameter combinations:

  • 720p + 4s + optimized → attribute_id A
  • 720p + 8s + optimized → attribute_id B
  • 4K + 4s + high → attribute_id C

The script automatically selects the correct attribute_id by matching your parameters (duration, resolution, compression_quality, generate_audio) against each rule's attributes. If the match fails, you get error 6010.

Fix: The bundled script now checks these video-specific parameters for smart credit_rule selection. Always use the script, not manual API construction.


Core Flow

1. GET /open/v1/product/list?app=ima&platform=web&category=<type>
   → REQUIRED: Get attribute_id, credit, model_version, model_name, form_config defaults

[If input image required]
2. Upload image → get public HTTPS URL
   → See "Image Upload" section below

3. POST /open/v1/tasks/create
   → Must include: attribute_id, model_name, model_version, credit, cast, prompt (nested!)

4. POST /open/v1/tasks/detail  {"task_id": "..."}
   → Poll until medias[].resource_status == 1
   → Extract url from completed media

Image Upload (Required Before Image Tasks)

The IMA Open API does NOT accept raw bytes or base64 images. All image inputs must be public HTTPS URLs.

When a user provides an image (local file, bytes, base64), you must upload it first and get a URL. This is exactly what the IMA frontend does before every image task.

Real Upload Flow (from IMA Frontend Source)

The frontend uses a two-step presigned URL flow via the IM platform:

Step 1: GET /api/rest/oss/getuploadtoken   → returns { ful, fdl }
          ful = presigned PUT URL (upload destination, expires ~7 days)
          fdl = final CDN download URL (use this as input_images value)

Step 2: PUT {ful}  with raw image bytes + Content-Type header
          → image is stored in Aliyun OSS: zhubite-imagent-bot.oss-us-east-1.aliyuncs.com
          → accessible via CDN: https://ima-ga.esxscloud.com/...

Step 1: Get Upload Token

GET https://imapi-qa.liveme.com/api/rest/oss/getuploadtoken

Required query parameters (11 total — sourced directly from frontend generateUploadInfo):

Parameter Example Description
appUid ima_xxx... Use IMA API key directly — no separate login needed
appId webAgent App identifier (fixed)
appKey 32jdskjdk320eew App secret (fixed, used for sign generation)
cmimToken ima_xxx... Use IMA API key directly — same as appUid
sign 117CF6CF... IM auth HMAC: SHA1("webAgent|32jdskjdk320eew|{timestamp}|{nonce}").upper()
timestamp 1772042430 Unix timestamp (seconds), generated per request
nonce CxI1FLI5ajLJZ1jlxZmeg Random nonce string, generated per request
fService privite Fixed: storage service type
fType picture picture for images, video, audio
fSuffix jpeg File extension: jpeg, png, mp4, mp3
fContentType image/jpeg MIME type of the file

简化认证:直接使用 IMA API key 填充 appUidcmimToken 参数,无需单独获取凭证。

Response:

{
  "ful": "https://zhubite-imagent-bot.oss-us-east-1.aliyuncs.com/webAgent/privite/2026/02/26/..._uuid.jpeg?Expires=...&OSSAccessKeyId=...&Signature=...",
  "fdl": "https://ima-ga.esxscloud.com/webAgent/privite/2026/02/26/..._uuid.jpeg",
  "ful_expire": "...",
  "fdl_expire": "...",
  "fdl_key": "..."
}

Step 2: Upload Image via Presigned URL

PUT {ful}
Content-Type: image/jpeg
Body: [raw image bytes]

No auth headers needed — the presigned URL already encodes the credentials.

Step 3: Use fdl as the Image URL

After the PUT succeeds, use fdl (the CDN URL) as the value for input_images / src_img_url.

Quick Reference

Task Types (category values)

category Capability Input
text_to_image Text → Image prompt
image_to_image Image → Image prompt + input_images
text_to_video Text → Video prompt
image_to_video Image → Video prompt + input_images
first_last_frame_to_video First+Last Frame → Video prompt + src_img_url[2]
reference_image_to_video Reference Image → Video prompt + src_img_url[1+]
text_to_music Text → Music prompt

Detail API status values

Each media in medias[] has two fields:

Field Type Values Description
resource_status int (or null) 0, 1, 2, 3 0=处理中, 1=可用, 2=失败, 3=已删除。API 可能返回 null,需当作 0。
status string "pending", "processing", "success", "failed" 任务状态文案。轮询时以 resource_status 为准;status == "failed" 表示失败。

Poll on resource_status first, then ensure status is not "failed":

resource_status status Meaning Action
0 or null pending / processing 处理中 Keep polling; do not stop (null = 0)
1 success (or completed) 完成 Read url; stop only when all medias are 1
1 failed 失败 (status 优先) Stop, handle error
2 any 失败 Stop, handle error
3 any 已删除 Stop

Important: (1) Treat resource_status: null as 0. (2) Stop only when all medias have resource_status == 1. (3) When resource_status=1, still check status != "failed".


API 1: Product List

GET /open/v1/product/list?app=ima&platform=web&category=text_to_image

Internally calls downstream /v1/products/listv2. Returns a V2 tree structure: type=2 nodes are model groups, type=3 nodes are versions (leaves). Only type=3 nodes contain credit_rules and form_config.

webAgent is auto-converted to ima by the gateway — you can use either value for app.

[
  {
    "id": "SeeDream",
    "type": "2",
    "name": "SeeDream",
    "model_id": "",
    "children": [
      {
        "id": "doubao-seedream-4-0-250828",
        "type": "3",
        "name": "SeeDream 4.0",
        "model_id": "doubao-seedream-4.0",
        "credit_rules": [
          { "attribute_id": 332, "points": 5, "attributes": { "default": "enabled" } }
        ],
        "form_config": [
          { "field": "size", "type": "tags", "value": "1K",
            "options": [{"label":"1K","value":"1K"}, {"label":"2K","value":"2K"}] }
        ]
      }
    ]
  }
]

How to pick a version for task creation:

  1. Traverse nodes to find type=3 leaves (versions)
  2. Use model_id and id (= model_version) from the leaf
  3. Pick credit_rules[].attribute_id matching your desired quality/size (attributes field shows the config)
  4. Use form_config[].value as default parameters values

credit_rules[].attribute_id → required for task creation as attribute_id. credit_rules[].points → required for task creation as credit and cast.points.


API 2: Create Task

POST /open/v1/tasks/create

Request Structure

{
  "task_type": "text_to_image",

  ]
}

Field Reference

Field Required Description
task_type Must match parameters[].category
parameters[].attribute_id From credit_rules[].attribute_id in product list
parameters[].model_id From type=3 leaf node model_id
parameters[].model_version From type=3 leaf node id
parameters[].app Use ima (or webAgent, auto-converted)
parameters[].platform Use web
parameters[].category Must match top-level task_type
parameters[].credit Must equal credit_rules[].points. Error 6006 if wrong.
parameters[].parameters.prompt The actual prompt text used by downstream service
parameters[].parameters.cast {"points": N, "attribute_id": N} — mirrors credit
parameters[].parameters.n Number of outputs (usually 1). Gateway flattens N>1 into separate resources.
parameters[].parameters.input_images image tasks Array of input image URLs
top-level src_img_url multi-image Array for first_last_frame / reference tasks

N-Field Flattening (Gateway Internal Logic)

When n > 1, the gateway automatically:

  1. Generates n independent resourceBizId values
  2. Deducts credits n times (one per resource)
  3. Creates n separate tasks in the downstream service

Response medias[] will contain n items. Poll until all have resource_status == 1.

Response

{
  "code": 0,
  "data": {
    "id": "task_abc123",
    "biz_id": "biz_xxx",
    "task_type": "text_to_image",
    "medias": [],
    "generate_count": 1,
    "created_at": 1700000000000,
    "timeout_at": 1700000300000
  }
}

data.id = task ID for polling. timeout_at = Unix ms deadline.


API 3: Task Detail (Poll)

POST /open/v1/tasks/detail
{"task_id": "<id from create response>"}

Poll every 2–5s (8s+ for video). Completed response:

{
  "id": "task_abc",
  "medias": [{
    "resource_status": 1,
    "status": "success",
    "url": "https://cdn.../output.jpg",
    "cover": "https://cdn.../cover.jpg",
    "format": "jpg",
    "width": 1024,
    "height": 1024
  }]
}

Polling stop condition (must implement exactly):

  • Treat resource_status: null (or missing) as 0 (processing). Do not stop when you see null; backend may serialize Go *int as null.
  • Stop only when ALL medias[].resource_status == 1 and no status == "failed". If you return on the first media with resource_status == 1 while others are still 0, the task is not fully done and you will keep polling or get inconsistent state.
  • Stop immediately if any status == "failed" or resource_status == 2 or resource_status == 3.

Task Type Examples

text_to_image ✅ Verified

No image input. src_img_url: [], input_images: []. See API 2 for full example.

text_to_video ✅ Verified

Extra fields vs text_to_image — all from form_config defaults:

{
  "task_type": "text_to_video",
  "src_img_url": [],
  "parameters": [{
    "attribute_id":  4838,
    "model_id":      "wan2.6-t2v",
    "model_name":    "Wan 2.6",
    "model_version": "wan2.6-t2v",
    "category":      "text_to_video",
    "credit":        3,
    "app": "ima", "platform": "web",
    "parameters": {
      "prompt":          "a puppy dancing happily, sunny meadow",
      "negative_prompt": "",
      "prompt_extend":   false,
      "duration":        5,
      "resolution":      "1080P",
      "aspect_ratio":    "16:9",
      "shot_type":       "single",
      "seed":            -1,
      "n":               1,
      "input_images":    [],
      "cast":            {"points": 3, "attribute_id": 4838}
    }
  }]
}

Video-specific fields from form_config: duration (seconds), resolution, aspect_ratio, shot_type, negative_prompt, prompt_extend. Poll every 8s (video generation is slower). Response medias[].cover = first-frame thumbnail.

text_to_music

No image input. src_img_url: [], input_images: [].

image_to_image ✅ Verified

{
  "task_type": "image_to_image",
  "src_img_url": ["https://...input.jpg"],
  "parameters": [{
    "attribute_id":  8560,
    "model_id":      "doubao-seedream-4.5",
    "model_version": "doubao-seedream-4-5-251128",
    "category":      "image_to_image",
    "credit":        5,
    "app": "ima", "platform": "web",
    "parameters": {
      "prompt":       "turn into oil painting style",
      "size":         "4k",
      "n":            1,
      "input_images": ["https://...input.jpg"],
      "cast":         {"points": 5, "attribute_id": 8560}
    }
  }]
}

⚠️ size must be from form_config options (e.g. "2k", "4k", "2048x2048"). "adaptive" is NOT valid for SeeDream 4.5 i2i — causes error 400. Top-level src_img_url and parameters.input_images must both contain the input image URL. Some i2i models (e.g. doubao-seededit-3.0-i2i) may not be available in test environments — fall back to SeeDream 4.5.

image_to_video / first_last_frame_to_video / reference_image_to_video

"src_img_url": ["https://first-frame.jpg", "https://last-frame.jpg"]

Index 0 = first frame (or reference), index 1 = last frame (first_last_frame only).


Common Mistakes

Mistake Fix
attribute_id not from credit_rules Always fetch product list first
credit value wrong Must exactly match credit_rules[].points — error 6006
prompt at wrong location Put prompt in parameters[].parameters.prompt (nested), not only at top level
Polling biz_id instead of id Use id (task ID) for /tasks/detail
Single-poll instead of loop Poll until resource_status == 1 for ALL medias
Missing app / platform in parameters Required fields — use ima / web
category mismatch parameters[].category must match top-level task_type
resource_status == 2 not handled Check for failure, don't loop forever
status == "failed" ignored resource_status=1 + status="failed" means actual failure
n > 1 and only checking first media All n media items must reach resource_status == 1
