## When to prefer this

Use this endpoint when you need the USD price of a Base network token on a specific past date — ideal for cost basis calculations, tax reporting, P&L analysis, or backtesting trading strategies. Prefer this over live-price endpoints when historical accuracy on a particular calendar date is required.

## Known failure modes

- Invalid or non-existent token contract address returns an error or null price
- Date in wrong format (not YYYY-MM-DD) causes a validation error
- Date too far in the past or future may return no price data
- Token not indexed by Covalent on Base returns no result
- Network or payment failure results in no response
