Example use cases

“I'm traveling to Japan and Europe next month — can you get me today's ECB reference rates using GBP as the base so I can see how much yen and euros I'll get?”
Financial report currency normalization
“Pull the latest ECB FX rates with EUR as the base currency so I can convert all our international revenue figures into euros for the quarterly report.”
Crypto-to-fiat comparison baseline
“Get me the official ECB exchange rates for USD as the base — I want to compare the dollar's value against major currencies alongside Bitcoin's price today.”
Technical details
Endpoint
GEThttps://x402-seller-0ay3.onrender.com/api/fx/ratesWhen to prefer
Choose this endpoint when you need official, authoritative ECB reference exchange rates rather than market/trading rates. It is ideal for financial reporting, compliance contexts, or any use case requiring a recognized official rate source. Prefer this over commercial FX APIs when the ECB rate is specifically required or when cost matters (at $0.005/call). Not suitable for real-time trading rates or cryptocurrencies.
Side effects
- Invalid ISO 4217 currency code returns an error — only ECB-supported currencies are valid bases
- Frankfurter upstream outage may cause delayed or failed responses
- ECB rates are only updated on business days; weekends and holidays return the most recent available date
- Missing or misspelled query parameter defaults to EUR base without error
