POSThttps://fx.withzero.ai/run?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need free, reliable currency conversion using official ECB rates with no API key or usage limits. Ideal for finance apps, travel cost estimation, invoice conversion, or any scenario requiring accurate multi-currency conversion. Prefer over paid forex APIs for non-commercial, informational, or agent-driven use cases where ECB rates are acceptable.
Side effects
- Invalid or unsupported currency ISO code returns an error — only 30+ ECB-supported currencies are available
- Amount of 0 or negative is rejected by schema (exclusiveMinimum: true)
- ECB rates are updated once per business day, so weekend/holiday rates may reflect the last available business day
- Network timeout if Frankfurter API is unreachable
