Technical details
Endpoint
POSThttps://currency-api-production-4a8d.up.railway.app/rates/convertWhen to prefer
Use this endpoint when you need to convert a specific monetary amount between two fiat currencies using authoritative ECB rates. Prefer this over generic lookup endpoints when you need the actual converted value (not just the rate). Best for EUR-paired and major fiat conversions; not suitable for cryptocurrency conversion or historical date-specific rates (use the historical endpoint instead).
Side effects
- Unsupported currency code (non-ECB-listed ISO 4217 codes like crypto or obscure currencies) returns an error
- Missing required fields (from, to, or amount) result in a validation error
- ECB rate unavailable for a weekend/holiday may return the most recent available rate or an error
- Negative or zero amount may be rejected
- Network or upstream Frankfurter API unavailability causes a 5xx error
