How this service works
Fiat exchange rates (ECB via Frankfurter) and crypto prices (CoinGecko) with x402 payments.
Output
A JSON object containing the base currency, the date of the rates, a map of target currency codes to their exchange rates relative to the base, a cached boolean indicating if the response was served from cache, and the data source (ECB via Frankfurter).
Example use cases
Multi-currency invoice pricing
“I'm billing a client in Europe — what are the current exchange rates from USD to EUR, GBP, and CHF so I can show them the equivalent prices?”
Daily FX dashboard update
“Pull the latest exchange rates with EUR as the base currency against USD, JPY, and GBP so I can update our finance dashboard for today.”
Travel budget planning
“I'm heading to Japan and the UK next month — can you get me today's exchange rates from USD to JPY and GBP so I can estimate my spending budget?”
Technical details
Endpoint
POSThttps://currency.payapi.market/rates/latest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need reliable, ECB-sourced fiat currency exchange rates at low cost ($0.001 USDC per call). Prefer it over alternatives when you need official ECB reference rates for EUR-denominated or multi-currency lookups, or when working in a crypto-native payment context (x402/USDC). Not suitable when you need intraday tick-level FX rates or real-time crypto prices (use the sibling crypto endpoint for that).
Side effects
- Unsupported or invalid base currency ISO code returns an error
- Invalid symbols in the target list may be ignored or cause an error
- Payment failure (x402) if USDC balance is insufficient
- Rate data may be cached or slightly delayed relative to real-time market prices
- ECB rates are typically end-of-day, not intraday tick data
