Technical details
Endpoint
POSThttps://agent.maddegen.art/hub/api/v1/tools/price_history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured historical price data with pre-computed risk metrics (drawdown, volatility) for any crypto asset identifiable by symbol, CoinGecko ID, or on-chain address across 17 EVM chains. It is especially useful when you need both raw price series and summary analytics in a single call without building your own calculations.
Side effects
- Unknown or unsupported asset symbol/ID returns an error
- Invalid chain identifier causes request rejection
- Requesting hourly interval for more than 30 days is not allowed
- Contract address not found on specified chain returns empty or error
- Network timeout may occur for longer historical queries
