Implementation notes
When to use ExchangeRate-API
ExchangeRate-API suits projects that need a simple, developer-friendly currency API with a meaningful free tier. At 1,500 calls/month, it comfortably covers a single-user personal finance app or a low-traffic widget that caches conversions for a day.
Common pitfalls
- The free plan updates exchange rates once per day, not in real time. If your application displays currency conversions and needs intraday accuracy (for financial applications, for example), the free tier is inappropriate.
- ExchangeRate-API uses versioned endpoints (`v6`). Previous versions (`v4`, `v5`) have been deprecated and now redirect or return errors without documentation. Always use the v6 base URL: `https://v6.exchangerate-api.com/v6/{key}/latest/{base}`.
- The standard response includes all 161 supported currencies in a single JSON object. There is no way to request a subset on the free tier — the response is always the full rates object, which is about 4KB per call.
- The `conversion_rates` field uses ISO 4217 currency codes, but a few older currency codes used by the API differ from what some libraries expect (e.g., the API uses `XOF` for West African CFA franc, which some financial libraries label differently).
