Quota Guarded Rates
with ExchangeRate-API
Branch on remaining quota between the keyed and Open Access rate endpoints.
- Read the plan quota and number of requests remaining for the API key before deciding which rate endpoint to use.
- Fetch the latest exchange rates through the authenticated keyed endpoint because quota is still available.
- Fall back to the no-key Open Access endpoint for once-daily rates because the keyed quota has been exhausted.
What you'll need to have ready
- apiKey: Your ExchangeRate-API dashboard API key.
- baseCode: ISO 4217 three-letter base currency code (e.g. USD).
