Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-forex-historicalWhen to prefer
Use this endpoint when you need the authoritative ECB official reference rate for a specific past date — ideal for financial reconciliation, regulatory or tax reporting at historical rates, computing time-period returns, or academic financial research. Prefer this over live-rate endpoints when the exact date matters and reproducibility is required.
Side effects
- Date before 1999 returns no data or error — ECB reference rates only available from 1999 onward
- Weekend or public holiday dates may not have an ECB rate — ECB does not publish rates on non-business days
- Unsupported or obscure currency pair returns an error — not all emerging currencies are covered by ECB
- Malformed date format causes a parsing error
- Future dates are not supported — endpoint only serves historical data
