# 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/completions` returns 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.

## Endpoint catalog

### Exchange (CEX) — 7 endpoints

### On-Chain — 7 endpoints

| Path                           | Method   | Tier | Required                 |
| ------------------------------ | -------- | ---- | ------------------------ |

| `/surf/onchain/sql`            | **POST** | T3   | `{ sql: "SELECT ..." }`  |

**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.)

### Web — 1 endpoint

| Path              | Tier | Required |
| ----------------- | ---- | -------- |
| `/surf/web/fetch` | T2   | `url`    |

## Example flows

**1. "Who is wallet X and what do they hold?"**

```bash
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?"**

```bash
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."**

```bash
# 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?"**

```bash
# 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.
