Editor's Notes & Deep Dive
Key Features
- →GET /rates?base=USD returns exchange rates with a date stamp
- →GET /rates?base=USD&date=2026-01-01 fetches historical rates
- →Also exposes /vat-rates and /countries for VAT compliance
Rate Limits & Quotas
No published hard limit; the host is a small Rails app behind Cloudflare. Keep usage polite.
Known Issues & Pitfalls
- !Rates are sourced from the ECB daily fix — not real-time FX
- !Base currency must be one of ~30 ECB reference currencies
How It Compares
Less breadth than currency-api-currency-exchange (fawazahmed0) but adds VAT lookup. Use fawazahmed0 for FX breadth, VATComply for tax compliance.
