Publish to Social

Post a finished agent-media video (an R2 video_url from any of the video skills) to the user's connected social channels — TikTok, Instagram, or X. Works from three surfaces: REST, the CLI (agent-media social ...), and MCP tools (social_channels / social_connect / social_publish). All calls use the user's Authorization: Bearer ma_... token against https://api.agent-media.ai.

1. Connect a channel (one-time, requires the human)

GET    /v1/social/providers             -> connectable networks: tiktok, instagram, instagram-standalone, x
POST   /v1/social/connect { provider }  -> { url }   # the user opens this OAuth url and authorizes
GET    /v1/social/channels              -> { channels: [{ id, name, provider, profile, picture }] }
DELETE /v1/social/channels/:channelId   -> disconnect

The connect step returns an OAuth URL the human must open and authorize — an agent cannot complete OAuth itself. Once authorized, the channel appears in /v1/social/channels with an id you pass to publish.

CLI: agent-media social providers · agent-media social connect x · agent-media social channels. MCP: social_connect { provider } (returns the URL for the user) · social_channels.

2. Publish a video

curl -X POST https://api.agent-media.ai/v1/social/publish \
  -H "Authorization: Bearer ma_..." -H "Content-Type: application/json" \
  -d '{ "video_url": "https://pub-...r2.dev/generation-outputs/<user>/<job>/...mp4",
        "channel_ids": ["<channel-id-from-/channels>"],
        "caption": "made with agent-media",
        "type": "now" }'    # or "type":"schedule" + "date":"2026-06-01T10:00:00.000Z"

CLI: agent-media social publish --video <url> --channels <id,id> --caption "..." (add --at <iso> to schedule). MCP: social_publish { video_url, channel_ids, caption, type }.

video_url must be an agent-media R2 URL (the output of a video skill) — agent-media re-hosts it on the publishing provider for you. channel_ids come from /v1/social/channels. Per-network requirements (e.g. X reply settings) are filled in server-side; you don't send them.

Returns { success: true, media_id, post_ids: ["..."] }. A real post was created only when post_ids is non-empty — treat an empty post_ids as a failure, not a success.

Typical flow

Produce a video → make_ugc → final_output.video_url.
If the user has no connected channel, send them to connect (step 1) — you can't OAuth for them.
Publish that video_url to the chosen channel_ids; confirm post_ids came back.

Note: social operations run on a shared rate budget — don't poll; connect once and publish on demand.
