Technical details
Endpoint
POSThttps://agenttoll.dev/paid/business/fx-ecb?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, official ECB FX rates rather than market mid-rates or bank rates — ideal for compliance, accounting, invoicing, and financial reporting use cases that require a recognized official source. Prefer it over generic FX APIs when ECB authority or historical ECB-specific rates are required.
Side effects
- Invalid base currency code returns an error or empty rates
- Requested date falls on a weekend or ECB holiday when no rates are published, returning nearest available or an error
- Unrecognized symbol in the symbols parameter may be silently omitted or cause an error
- Future dates return no data
- Network or upstream ECB data feed unavailability causes a 5xx error
