Endpoint
GEThttps://api.x402node.dev/prices/historical?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the USD price of a specific token at a past point in time — for tax cost-basis calculations, backtesting trading strategies, or financial accounting. Prefer over current-price endpoints when historical accuracy at a specific timestamp is required. Use when the LLM's training data cannot reliably supply accurate historical prices.

- CoinGecko ID is invalid or unrecognized — lookup fails
- Chain not supported — returns error
- Price data unavailable for the exact timestamp — may return nearest available or error
