| name | crypto-data |
| description | Use for any crypto data question — token/coin prices, FX, commodities, stocks, OHLC history, DEX pairs and liquidity, DeFi TVL, yield/APY pools, on-chain SQL, wallet labels and net worth, social mindshare, news, or raw JSON-RPC against a chain. Routes across five tools that overlap heavily, so it also says which one to use and which are FREE — blockrun_price (crypto/FX/commodities free, Pyth), blockrun_dex (free, DexScreener), blockrun_defi (DefiLlama TVL + yields), blockrun_surf (83 endpoints — on-chain SQL, 100M+ wallet labels, social), blockrun_rpc (40 chains). No API keys, pay-per-call in USDC via x402. |

Crypto Data
Five tools cover crypto data and they overlap. Pick by cost first — two of them are free, and paying for a quote you could get for nothing is the most common mistake here.
Route by cost — check this before calling anything
| Question | Tool | Cost |
|---|
| What's BTC/ETH/any coin worth right now? | blockrun_price action:"price" category:"crypto" | FREE |
| Crypto OHLC history | blockrun_price action:"history" category:"crypto" | FREE |
| FX rate / commodity (gold, oil) | blockrun_price category:"fx" or "commodity" | FREE |
| Which symbols exist? | blockrun_price action:"list" | FREE |
| DEX pair, liquidity, volume, contract | blockrun_dex | FREE |
| Stock quote / history (12 markets) | blockrun_price category:"stocks" | $0.0020 |
| Token price by contract address | blockrun_defi path:"prices/{coins}" | $0.0020 |
| Raw JSON-RPC on 40 chains | blockrun_rpc | $0.0030 |
| Protocol TVL, chain TVL, yields/APY | blockrun_defi | $0.0060 |
| Everything below (on-chain SQL, wallet labels, social, news, unlocks, liquidations, ETF flows) | blockrun_surf | $0.0085 |
| Raw SQL over 80+ ClickHouse tables | blockrun_surf path:"onchain/sql" | $0.0085 |
Every price below is what x402 actually charges (the base plus the gateway's $0.001 flat fee), verified against live payment-required headers — not the base you may see in a 402 body.
The rule: a plain crypto price or a DEX pair is free. Only reach for blockrun_surf when you need something the free tools genuinely do not have — labels, SQL, social, news, unlocks.
Prediction markets are never a Surf question. Surf carries prediction-market/* endpoints, but Predexon (blockrun_markets) serves the same Polymarket/Kalshi data at the same $0.0085 — and adds wallet clustering, smart money, sports, UMA, and five more venues that Surf does not have at all. Price is no longer the argument (it was 7.5× cheaper before 2026-07-15); coverage is, and it is decisive. Route odds, positions and market history to skills/prediction-markets/SKILL.md.
blockrun_price — quotes & history (Pyth-backed)
Free for crypto, FX and commodities. $0.0020 only for stocks.
blockrun_price({ action: "price", category: "crypto", symbol: "BTC-USD" })
blockrun_price({ action: "history", category: "crypto", symbol: "ETH-USD",
resolution: "1h", from: 1750000000, to: 1750086400 })
blockrun_price({ action: "price", category: "fx", symbol: "EUR-USD" })
blockrun_price({ action: "price", category: "commodity", symbol: "XAU-USD" })
blockrun_price({ action: "list", category: "crypto" })
blockrun_price({ action: "price", category: "stocks", symbol: "AAPL", market: "us" })
Stock markets: us, hk, jp, kr, gb, de, fr, nl, ie, lu, cn, ca — market is required when category:"stocks".
blockrun_dex — DEX pairs & liquidity (DexScreener)
Free, no payment. Use it for anything pair- or contract-shaped.
blockrun_dex({ query: "SOL" })
blockrun_dex({ symbol: "PEPE" })
blockrun_dex({ token: "So11111111111111111111111111111111111111112" })
blockrun_dex({ query: "WETH", chain: "base" })
blockrun_defi — TVL & yields (DefiLlama)
Path-based, GET only. Base only — sol.blockrun.ai does not serve /v1/defillama/*
and answers 404, which reads like a bad path rather than a wrong chain. The tool checks
the active chain and refuses with that explanation before spending the round trip; if the
user needs DeFi data, switch back with blockrun_wallet action:"chain" chain:"base".
| path | cost | returns |
|---|
protocols | $0.0060 | every DeFi protocol ranked by TVL |
protocol/{slug} | $0.0060 | one protocol's TVL history + chain breakdown |
chains | $0.0060 | TVL by chain |
yields | $0.0060 | yield pools with APY + TVL (large — filter client-side) |
prices/{coins} | $0.0020 | token prices by contract, e.g. base:0x8335…,coingecko:ethereum |
blockrun_defi({ path: "protocol/aave-v3" })
blockrun_defi({ path: "chains" })
blockrun_defi({ path: "yields" })
blockrun_defi({ path: "prices/coingecko:ethereum" })
blockrun_surf — the things nothing else has
83 endpoints. Reach here when the free tools cannot answer it: on-chain SQL, 100M+ labeled wallets across 13 chains, social/CT intelligence, news, tokenomics, liquidations, ETF flows, VC portfolios. Full catalog and recipes: skills/surf/SKILL.md.
blockrun_surf({ path: "wallet/labels/batch", params: { addresses: "0xabc,0xdef" } })
blockrun_surf({ path: "wallet/net-worth", params: { address: "0xabc" } })
blockrun_surf({ path: "token/tokenomics", params: { symbol: "ARB" } })
blockrun_surf({ path: "market/etf", params: { symbol: "BTC" } })
blockrun_surf({ path: "social/mindshare", params: { project: "base" } })
blockrun_surf({ path: "onchain/sql", body: {
sql: "SELECT token_address, count() FROM ethereum.dex_trades WHERE block_time > now() - INTERVAL 1 DAY GROUP BY 1 ORDER BY 2 DESC LIMIT 10"
}})
blockrun_rpc — raw chain access
40 chains, one endpoint, no node, no key. $0.0030/call (batches charge per element, plus one flat fee per request). See [`skills/rpc/SKILL.md`](../rpc/SKILL.md).
blockrun_rpc({ network: "base", method: "eth_blockNumber", params: [] })
Worked Examples
1. "What's BTC at?" — do not pay for this
blockrun_price({ action: "price", category: "crypto", symbol: "BTC-USD" })
Not blockrun_surf({ path: "market/price" }) — that is $0.0085 for an answer you can get free.
2. "Is this token legit?" ← compound, mostly free
blockrun_dex({ token: "0xCONTRACT" })
blockrun_surf({ path: "token/holders", params: { address: "0xCONTRACT" } })
blockrun_surf({ path: "token/tokenomics", params: { symbol: "TKN" } })
Start free. Only pay once the free signal says it is worth a closer look.
3. "Who owns this wallet and what do they hold?"
blockrun_surf({ path: "wallet/labels/batch", params: { addresses: "0xWHALE" } })
blockrun_surf({ path: "wallet/net-worth", params: { address: "0xWHALE" } })
blockrun_surf({ path: "wallet/protocols", params: { address: "0xWHALE" } })
4. "Where's the best yield right now?"
blockrun_defi({ path: "yields" })
blockrun_defi({ path: "chains" })
5. "Give me the macro picture"
blockrun_surf({ path: "market/etf", params: { symbol: "BTC" } })
blockrun_surf({ path: "exchange/funding-history", params: { symbol: "BTCUSDT" } })
blockrun_surf({ path: "market/liquidation/chart" })
blockrun_surf({ path: "market/fear-greed" })
6. "Is gold up today?" — also free
blockrun_price({ action: "price", category: "commodity", symbol: "XAU-USD" })
