How this service works
Historical token price by contract at a Unix timestamp
Output
Returns the historical USD price (or equivalent denomination) of the specified ERC-20 token contract at the requested Unix timestamp, allowing point-in-time valuation of on-chain assets
Example use cases
Portfolio historical valuation snapshot
“I need to know what the USDC token at contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 was worth on Ethereum at Unix timestamp 1690000000 so I can calculate my portfolio value at that point.”
Transaction-time price audit
“Can you look up the price of the token at contract 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum exactly when a transaction happened — the Unix timestamp is 1672531200?”
DeFi yield calculation at entry point
“What was the price of the Uniswap token at contract 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Unix timestamp 1680000000? I need it to work out my returns since I entered that position.”

Endpoint
GEThttps://santyvv-x402.santyvv1993.workers.dev/api/crypto/token-price-historical?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the price of a specific ERC-20 token at an exact past moment in time identified by Unix timestamp and contract address — ideal for transaction audits, historical portfolio valuations, P&L calculations, and tax reporting where point-in-time accuracy is critical. Prefer this over live-price endpoints when the moment of interest is in the past.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Unix timestamp out of supported historical range returns no data
- Unsupported chain or network returns an error
- Token contract with no price feed history at that timestamp returns null or error
- Missing required query parameters returns a 400-level validation error
