Technical details
Endpoint
POSThttps://public.zapper.xyz/x402/historical-token-priceWhen to prefer
Use this endpoint when you need the USD price of a specific token at a past point in time on a supported EVM chain. Ideal for portfolio P&L calculations, historical trade valuation, tax reporting, or auditing past DeFi positions. Prefer this over current-price endpoints when the timestamp is historical rather than real-time.
Side effects
- Invalid token contract address returns error or empty result
- Unsupported chain ID results in no data found
- Timestamp too far in the past may return null or unavailable price
- Malformed unix timestamp (wrong units, e.g. seconds instead of milliseconds) causes incorrect or missing results
- Token with no price history at that timestamp returns empty or null price
