How this service works
BlockRun independently tests AI agents that move money: did they pay the right party the right amount, avoid being scammed, stay within their mandate, and tell the truth afterwards. Scored from the ledger, not by a model judge.
Output
Returns a time series of historical price data for the specified token symbol, including price points over historical intervals.
Example use cases
Example prompt
“Pull the price history for ETH from BlockRun so I can see how its value has changed over time.”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/surf/market/price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical price data for a specific cryptocurrency token identified by its ticker symbol, especially within the BlockRun.AI ecosystem where other related market data (OHLCV, Fear & Greed, DeFi TVL) is also available. Prefer this over full OHLCV if you only need price (not open/high/low/volume) history.
Side effects
- Invalid or unrecognized token symbol returns error
- Missing required symbol parameter returns 400 bad request
- Payment of 0.001 USDC not processed results in 402 payment required
- Token with no price history returns empty dataset
- Network timeout or upstream data unavailability
