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 <!-- br:chains.rpc -->40<!-- /br:chains.rpc --> 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`](../prediction-markets/SKILL.md).

## blockrun_price — quotes & history (Pyth-backed)

Free for crypto, FX and commodities. $0.0020 only for stocks.

```ts

blockrun_price({ action: "price", category: "crypto", symbol: "BTC-USD" }) // FREE

blockrun_price({ action: "history", category: "crypto", symbol: "ETH-USD",

resolution: "1h", from: 1750000000, to: 1750086400 }) // FREE

blockrun_price({ action: "price", category: "fx", symbol: "EUR-USD" }) // FREE

blockrun_price({ action: "price", category: "commodity", symbol: "XAU-USD" }) // FREE — gold

blockrun_price({ action: "list", category: "crypto" }) // FREE — discovery

blockrun_price({ action: "price", category: "stocks", symbol: "AAPL", market: "us" }) // $0.0020

```

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.

```ts

blockrun_dex({ query: "SOL" }) // search pairs

blockrun_dex({ symbol: "PEPE" }) // search by symbol

blockrun_dex({ token: "So11111111111111111111111111111111111111112" }) // one token

blockrun_dex({ query: "WETH", chain: "base" }) // scope to a chain

```

## blockrun_defi — TVL & yields (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` |

```ts

blockrun_defi({ path: "protocol/aave-v3" })

blockrun_defi({ path: "chains" })

blockrun_defi({ path: "yields" }) // big payload — filter after

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`](../surf/SKILL.md).

```ts

blockrun_surf({ path: "wallet/labels/batch", params: { addresses: "0xabc,0xdef" } }) // CEX/Whale/MEV/Bot

blockrun_surf({ path: "wallet/net-worth", params: { address: "0xabc" } })

blockrun_surf({ path: "token/tokenomics", params: { symbol: "ARB" } }) // unlocks + vesting

blockrun_surf({ path: "market/etf", params: { symbol: "BTC" } }) // ETF flows

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"

}}) // $0.0085

```

## blockrun_rpc — raw chain access

<!-- br:chains.rpc -->40<!-- /br:chains.rpc --> 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).

```ts

blockrun_rpc({ network: "base", method: "eth_blockNumber", params: [] })

```

## Worked Examples

### 1. "What's BTC at?" — do not pay for this

```ts

blockrun_price({ action: "price", category: "crypto", symbol: "BTC-USD" }) // FREE

```

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

```ts

blockrun_dex({ token: "0xCONTRACT" }) // FREE — liquidity, volume, pairs

blockrun_surf({ path: "token/holders", params: { address: "0xCONTRACT" } }) // concentration

blockrun_surf({ path: "token/tokenomics", params: { symbol: "TKN" } }) // unlock cliff coming?

```

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?"

```ts

blockrun_surf({ path: "wallet/labels/batch", params: { addresses: "0xWHALE" } }) // CEX? Whale? MEV bot?

blockrun_surf({ path: "wallet/net-worth", params: { address: "0xWHALE" } })

blockrun_surf({ path: "wallet/protocols", params: { address: "0xWHALE" } }) // Aave/Lido/Uni positions

```

### 4. "Where's the best yield right now?"

```ts

blockrun_defi({ path: "yields" }) // filter by chain/TVL/APY client-side — payload is large

blockrun_defi({ path: "chains" }) // where the money actually is

```

### 5. "Give me the macro picture"

```ts

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

```ts

blockrun_price({ action: "price", category: "commodity", symbol: "XAU-USD" }) // FREE

```
