How this service works
Convert an amount from one currency to another at the latest ECB reference rate, with the rate and fixing date.
Output
Returns a JSON object with the converted amount (result), the exchange rate used (rate), the fixing date (fixingDate), the source currency (from), the target currency (to), the original amount (amount), a human-readable summary, source attribution, and a disclaimer. May also include a degraded flag if the rate data is not fully fresh.
Example use cases
Invoice amount in foreign currency
“I need to convert 12500 euros to US dollars using the official ECB rate — what's the result and what date was the rate fixed?”

“How much would 2000 British pounds be in Japanese yen at today's ECB reference rate?”
Cross-border payment estimate
“Convert 8750 CHF to EUR using the ECB rate so I can estimate how much to send in a wire transfer — include the rate and fixing date.”
Technical details
Endpoint
GEThttps://fx-ecb.x402tookit.com/fx-convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a currency conversion grounded in the official ECB reference rate with a clear fixing date — ideal for compliance, financial reporting, invoicing, or any context where the authoritative ECB source matters. Prefer over commercial FX APIs when auditability and official sourcing are required.
Side effects
- Unsupported currency code — the ECB only publishes rates for 30 currencies; non-ECB currencies return an error or null result
- Missing required parameters (amount, from, or to) result in a validation error
- Rate unavailable for the current day (e.g. weekend or holiday) — the API may use the most recent available fixing
- Invalid amount (non-numeric or negative) causes a bad request response
