What it does

Surf is an agent skill from BlockRunAI/ClawRouter. Use this skill — NOT browser or webfetch — 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. Paid through ClawRouter — x402 USDC from the local wallet, or BlockRun account credit if an API key is…

Its SKILL.md is about 4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Crypto and DeFi analysis, Smart contracts and Data warehousing. It works with x402, Circle USDC, ClickHouse and SQL. The repository describes itself as: The agent-native LLM router for autonomous agents. Every frontier model behind one wallet, <1ms local routing, USDC payments on Base & Solana via x402. The licence is MIT.

When your agent uses it

  • Tasks that involve Crypto and DeFi analysis
  • Tasks that involve Smart contracts
  • Tasks that involve Data warehousing

Example prompts

  • “/surf”

What it can do on your machine

Read from SKILL.md and the folder at commit b758e03. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Surf loads about 4k tokens when it runs. Until then it costs about 146 tokens; SKILL.md has 1,170 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~146
When it runs · the whole SKILL.md, loaded when a task matches
~4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 the same way ClawRouter pays for LLM calls — an x402 USDC micropayment from the local wallet, or a draw on BlockRun account credit if an API key is configured (verified working on both, 2026-09-05). No Surf account and no Surf API key either way. Upstream lives at api.asksurf.ai/gateway/v1 — ClawRouter forwards transparently.

Pricing — flat per call, the same for every endpoint.

Surf used to be tiered at $0.001 / $0.005 / $0.020. It is not any more: upstream now prices all three tiers identically (SURF_TIER_{1,2,3}_PRICE are equal). The Tier column in the catalog below still describes endpoint weight, but it no longer affects what you pay. Anything quoting the old tier prices is stale.

RailPrice per call
API key (api.blockrun.ai)$0.0075 — base rate, no transaction fee
Wallet, Solana$0.0075
Wallet, Base$0.0085

Verified 2026-09-05 by measurement, not from a price page: the API-key figure by diffing the account ledger across one call, the wallet figures by reading the amount in the x402 402 challenge, which quotes the price before anything is signed. Base and Solana genuinely differ for the same endpoint.

A 402 quote is authoritative for the rail that issued it — and only that rail. On the wallet rail the price arrives in the challenge before you pay, so if this table disagrees with it, believe the challenge and treat the table as stale.

Do NOT carry a wallet-rail 402 figure over to the API-key rail. The key rail issues no 402 at all, and the wallet quote includes the chain's transaction fee that account credit does not pay — on Base that is $0.0085 quoted against $0.0075 actually billed to an account. Reading across rails turns a correct number into a wrong one; it has already happened once.

The Base/Solana difference is deliberate, not drift: the $0.001 is the Base transaction fee, and Solana omitting it is a migration incentive. Solana being cheaper is expected — Solana priced above Base would be the bug worth reporting, since estimates generally assume the Base figure is the ceiling.

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 attaches payment transparently — an x402 header in wallet mode, a bearer token in API-key mode.

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 you are 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.

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.
