AllRatesToday provides accurate, real-time and historical currency exchange rate data through a simple REST API — mid-market rates from institutional interbank market data, fetched live, no markup, no spread. Plus official central-bank rates from 24 central banks for tax, audit, and compliance work.
Single-pair lookups are public — no API key needed:
curl "https://allratestoday.com/api/rate?source=USD&target=EUR"{ "rate": 0.92145, "source": "interbank" }Multi-target and historical data with a free API key:
curl -H "Authorization: Bearer YOUR_API_KEY" \
"https://allratestoday.com/api/v1/rates?source=USD&target=EUR,GBP,JPY"The official daily tables published by 24 central banks — ECB, US Federal Reserve (H.10), Bank of England, People's Bank of China, Reserve Bank of India, Bank of Canada, Central Bank of Sri Lanka, and more — served as clean JSON (or CSV) with the bank's own publication date on every response. History back to 1999 for some banks. These are the fixed, citable rates that tax filings, customs, audits, and compliant invoicing require.
