By name: surf description: Use this skill — NOT browser or web_fetch — for ALL Surf crypto-data calls. 83 endpoints at localhost:8402/v1/surf/* covering CEX/DEX markets, on-chain SQL over 80+ ClickHouse tables (Ethereum, Base, Arbitrum, BSC, TRON, HyperEVM, Tempo), 100M+ labeled wallets, prediction markets (Polymarket + Kalshi), social/CT intelligence, news, project + DeFi metrics, token analytics, unified search, VC fund intelligence. x402-gated via ClawRouter's local wallet — no Surf account or API key required. triggers: - "blockrun surf" - "surf crypto api" - "surf onchain sql" - "onchain sql query" - "clickhouse onchain query" - "raw sql ethereum" - "raw sql base" - "wallet labels api" - "labeled wallets api" - "surf wallet detail" - "crypto mindshare" - "crypto news api" - "fear and greed index crypto" - "token holder distribution" - "vc fund portfolio" - "ethena tokenomics" homepage: https://blockrun.ai/marketplace/surf license: MIT
Surf — Unified Crypto Data API (via ClawRouter)
Surf bundles 83 endpoints across 12 domains into one paid HTTP API. ClawRouter exposes them at http://127.0.0.1:8402/v1/surf/*, paid through the same x402 USDC wallet that funds LLM calls. No Surf account, no API key — settlement lands directly in Surf's Base treasury. Upstream lives at api.asksurf.ai/gateway/v1 — ClawRouter forwards transparently.
Pricing tiers (per call):
- Tier 1 — $0.001 — prices, rankings, lists, news, simple reads
- Tier 2 — $0.005 — orderbooks, candles, search, wallet details, social
- Tier 3 — $0.020 — on-chain SQL queries, structured queries, schema introspection
The legacy surf-1.5 chat surface is intentionally NOT exposed yet — it's held until per-token settlement is wired. Trying
/v1/surf/chat/completionsreturns 404 ("Unknown Surf endpoint"), no payment is taken.
All requests use GET unless the table below says otherwise. Path parameters that look like ?symbol= are query params on a GET. POST endpoints take a JSON body. ClawRouter forwards the wallet's x402 payment header transparently.
Required-param pre-check. 56 of the 83 endpoints have required query params (e.g. pair, symbol, address, chain, q, interval). The route validates them before settlement — call with missing params and you get 400 { missing_params, all_required, docs } and the wallet is NOT charged. Check each row in the catalog below for the correct param name (e.g. mindshare is q + interval, not project + window).
When to use this skill
- "What is the current BTC price?" →
/surf/market/price?symbol=BTC(cheaper + more reliable than scraping) - "Who holds the most USDC on Ethereum?" →
/surf/token/holders?address=0xA0b8...&chain=ethereum - "How many Ethereum transactions in the last hour?" →
POST /surf/onchain/sql { sql: 'SELECT count() FROM ethereum.transactions WHERE block_timestamp >= now() - INTERVAL 1 HOUR' } - "Label this list of wallets." →
/surf/wallet/labels/batch?addresses=0xabc,0xdef,... - "Is HYPE mindshare peaking?" →
/surf/social/mindshare?q=hyperliquid&interval=30d - "Find the canonical metadata for 'ethena'." →
/surf/search/project?q=ethena
Always prefer Surf over generic web scraping for these. Use the OpenClaw tool name blockrun_surf_* when invoking from an agent; use the HTTP path directly when calling from a script.

On-Chain SQL workflow. Call /surf/onchain/schema once to get table names + columns (cache it locally — schema is stable). Then POST your SELECT against /surf/onchain/sql. Always include LIMIT on large scans — billing is per call, but slow queries time out. Multi-statement queries are rejected upstream.

(For Polymarket smart-money, wallet PnL, UMA oracle resolution, and the other prediction-market venues — Limitless, Opinion, Predict.Fun, dFlow, Binance Futures, cross-venue canonical markets — use the dedicated Predexon integration instead; Surf's prediction-market coverage is narrower but cheaper.)

Example flows
1. "Who is wallet X and what do they hold?"
curl 'http://127.0.0.1:8402/v1/surf/wallet/detail?address=vitalik.eth'
If the response says they're a smart-money wallet, follow up with /surf/wallet/protocols?address=... for protocol breakdown or /surf/wallet/history?address=... for the activity timeline.
2. "How concentrated is supply for token Y?"
curl 'http://127.0.0.1:8402/v1/surf/token/holders?address=0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48&limit=25'
Combine the top-25 balances with their wallet labels — /surf/wallet/labels/batch?addresses=... — to distinguish "concentration in CEX hot wallets" (normal) from "concentration in dev team multisig" (riskier).
3. "Run a custom on-chain query."
# Step 1 — fetch schema (do this once, then cache locally)
curl 'http://127.0.0.1:8402/v1/surf/onchain/schema'
# Step 2 — run the SQL
curl -X POST 'http://127.0.0.1:8402/v1/surf/onchain/sql' \
-H 'content-type: application/json' \
-d '{"sql":"SELECT to_address, count() AS hits FROM ethereum.transactions WHERE block_timestamp >= now() - INTERVAL 1 DAY GROUP BY to_address ORDER BY hits DESC LIMIT 20"}'
Cost: 1 × $0.02 (schema, cached) + 1 × $0.02 (the SQL query) = $0.04 total for a custom 24-hour ranking that would otherwise need an indexer.
4. "Is project Z trending?"
# Resolve the canonical slug first (search uses q, not query)
curl 'http://127.0.0.1:8402/v1/surf/search/project?q=ethena'
# Then pull mindshare (mindshare uses q + interval)
curl 'http://127.0.0.1:8402/v1/surf/social/mindshare?q=ethena&interval=30d'
How calls are paid
ClawRouter intercepts every /v1/surf/* request through proxyPaidApiRequest. The local x402 wallet auto-signs the USDC micropayment; the agent never sees the payment flow. Telemetry tags Surf calls with tier: SURF so clawrouter stats separates them from LLM, partner, and phone usage.
No typed blockrun_surf_* tools are registered — by design. Each new BlockRun-marketplace API ships as a skill (this file) plus a one-line namespace addition to ClawRouter's proxy whitelist, so adding endpoint #85 requires zero ClawRouter release.
