How this service works
Live exchange rates and a conversion for ~170 currencies and the major crypto assets, with the European Central Bank reference rate beside each live one and the deviation between them - an independent check in the same answer. {from, to, amount}; send {} for USD against eight majors. Pay-per-call via x402.
Output
Returns a JSON object containing live exchange rates for each requested currency pair, the converted amount, the ECB reference rate for each pair, and the percentage or absolute deviation between the live rate and the ECB benchmark. Default response covers USD against eight major currencies when no parameters are supplied.
Example use cases
Travel budget currency conversion
“I'm heading to Japan and the UK next month. Can you convert 2000 USD to JPY and GBP and tell me the live rates plus how far they are from the ECB reference rate?”
Crypto portfolio fiat valuation
“How much is 1 BTC worth in EUR and CHF right now? Show me the live rate alongside the ECB benchmark so I can see if there's any deviation.”
Multi-currency invoice pricing
“I need to quote a client in four currencies — convert 5000 EUR to USD, GBP, CAD, and AUD using today's live rates, and include the ECB reference comparison for each.”
