Implementation notes
When to use Currency API (currencyapi.com)
Currency API (currencyapi.com) covers 170+ currencies with updates every 60 seconds on paid plans and daily on the free tier. At 300 calls/month free, it suits a personal finance app or static site that fetches fresh rates once daily and caches aggressively. Its response format is among the cleanest in the category.
Common pitfalls
- 300 calls/month resets on the first day of each calendar month, not 30 days from signup. A burst of development testing mid-month can leave you out of credits before the month ends.
- The `demo` API key returns a 429 for any endpoint that requires a real key. Requests with demo always return an empty data object rather than sample data, making it useless for testing. Register for a real free key immediately.
- Free tier updates rates once per day (on the `@daily` schedule). The `last_updated_at` field in the response shows the exact timestamp — do not assume 'latest' means 'current hour'. For intraday accuracy you need the $9.99/month Essential plan.
- The response wraps all currency values inside a `data` object keyed by currency code (e.g., `data.EUR.value`). Requesting a currency code that is not supported returns a 422 error, not a missing key — validate requested codes against the `/currencies` endpoint before querying.
