Endpoint

Use this endpoint when you need exchange rate data for a specific past date, such as for financial reconciliation, tax reporting, expense conversion, or historical analysis. Prefer this over a live-rate endpoint when the date in question is not today.
Side effects

- Unsupported or misspelled currency code returns an error or empty result
- Dates too far in the past or in the future may not be available
- Missing required query parameters may return a bad request error
- Payment failure (insufficient USDC balance) blocks the request
