How this service works
BlockRun — 103 onchain & market-data endpoints over x402: surf/* (prices, rankings, news, onchain SQL, social mindshare) and pm/* prediction markets (Polymarket, Kalshi, sports, Binance candles). GET { endpoint, ...query }. Mostly 1-2¢ caps. See onchain-data knowledge doc or vaaya/discover.
Output
Returns structured JSON containing the requested onchain or market data — prices, rankings, odds, candles, news items, social scores, or SQL result rows — depending on which of the 103 sub-endpoints is targeted.
Example use cases
Token price and ranking snapshot
“Get me the current price, market cap rank, and 24-hour change for SOL, ETH, and BTC using BlockRun's surf/prices endpoint.”
Prediction market odds check
“What are the current Polymarket and Kalshi odds for the 2024 US presidential election winner? Pull from BlockRun's pm endpoints.”
Onchain SQL data query
“Run an onchain SQL query against BlockRun to find the top 10 Uniswap v3 pools by 7-day volume — use the surf/sql endpoint.”

Choose BlockRun when you need broad coverage of crypto/onchain data and prediction markets through a single micropayment-based gateway, especially for agents that need to mix token prices, social sentiment, SQL onchain queries, and prediction market odds in one workflow without managing multiple API keys.
Side effects
- Invalid endpoint name returns an error indicating unrecognized route
- Missing required query parameters returns a validation error
- Insufficient USDC balance or x402 payment failure blocks the request
- Rate limits or upstream data source outages may return 503 or timeout
- Malformed SQL in onchain queries returns a query parse error
