Technical details
Endpoint
GEThttps://api.certaindata.ai/ca054d66abad4d6ea80ba43013b61743-cd/fx-rates/:baseWhen to prefer
Use this endpoint when you need exchange rates for one base currency against ALL published currencies in a single call, rather than fetching individual currency pairs one at a time. Prefer this for building currency conversion tables, multi-currency financial dashboards, or broad FX exposure analysis. Use the sibling single-pair endpoint if you only need one specific quote currency.
Side effects
- Invalid or unsupported base currency ISO code returns an error or empty result
- Future dates or dates before ECB publication history may return no data
- Weekend or holiday dates may return the most recent available business day rates
- Network or upstream ECB data outage may cause unavailability
- Malformed date format (not YYYY-MM-DD) may result in an error
