Endpoint
GEThttps://x402.orthogonal.com/abstractapi/v1/historicalWhen to prefer
Choose this endpoint when you need exchange rates for a specific past date rather than current live rates. It is ideal for financial reconciliation, accounting, tax reporting, or any use case where you need a definitive rate that was in effect on a given calendar day. Prefer this over the live conversion endpoint when you are not working with present-day transactions.
Side effects
- Invalid or unsupported currency code returns an error or empty result
- Date out of supported historical range returns an error
- Malformed date format (not YYYY-MM-DD) causes a bad request response
- Missing required parameters (date or base currency) may return an error or default behavior
- Rate limiting or payment failure returns a 402 or 429 status
