How this service works
Currency conversion + exchange rates for AI agents — give from, to, and an optional amount → the converted value at the latest ECB reference rate; or give just a base → all its latest rates. Pay-per-call in USDC via x402 — no signup, no API key. Use to price, convert, and reason about money across currencies mid-task.
Output
Returns the converted value at the latest ECB reference rate for a given currency pair and amount, or returns all current exchange rates for the specified base currency as a structured JSON object.
Example use cases
Example prompt
“How much is 250 US dollars in Japanese yen right now using the latest ECB rate?”

- Missing required 'from' or 'to' parameter when doing a conversion returns a 400-style error
- Payment failure via x402 if USDC balance is insufficient
- ECB rates not yet updated for the current day (rates typically updated around 16:00 CET on business days)
- Network timeout if Railway infrastructure is temporarily unavailable
