Example use cases
Example prompt
“What was the price of ETH (ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2) and LINK (coingecko:chainlink) at unix timestamp 1672531200? Use a 4h search window.”
Technical details
Endpoint
GEThttps://defillama.use.x402atlas.com/prices-historical?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need token prices at a specific point in the past, rather than current prices. Prefer it over current-price endpoints for historical PnL calculations, backtesting, or auditing DeFi positions at a given block time. Supports both on-chain contract addresses (chain:address format) and CoinGecko IDs.
Side effects
- Invalid or unrecognized coin identifier returns empty or partial results
- Unix timestamp out of supported historical range returns no price data
- Malformed coins parameter (wrong format) results in an error response
- searchWidth too narrow with no price data in range returns empty result
- Payment not processed results in 402 response before data is returned
