Exchangerate Api Rate Limits

ExchangeRate-API enforces per-API-key monthly request quotas tied to plan tier rather than per-second / per-minute rate limits. Free uses 1,500/month, Pro 30,000/month, Business 125,000/month, and Volume the largest allotment. When quota is exhausted the API returns an error envelope with error-type quota-reached. The no-key Open Access endpoint (open.er-api.com) is anti-abuse throttled and returns HTTP 429 with a 20-minute reset window.

Exchangerate Api Rate Limits is the machine-readable rate-limit profile for ExchangeRate-API on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 5 rate-limit definitions, measuring requests_per_month and requests.

The profile also includes 4 backoff/retry policies defined and response codes documented for quotaReached, quotaErrorType, and openAccessRateLimit.

Tagged areas include Rate Limiting, Currency Exchange, and Foreign Exchange.

Policies

Quota refresh
Monthly request quotas refresh on the day-of-month indicated by the quota endpoint response (refresh_day_of_month). Use the GET /v6/{key}/quota endpoint to programmatically track remaining requests.
Error envelope, not HTTP code
When the monthly quota is exceeded the API returns HTTP 200 with a JSON error envelope where result is "error" and error-type is "quota-reached". Clients must inspect the JSON body rather than relying solely on HTTP status codes.
Open Access rate limiting
The open.er-api.com endpoint is anti-abuse throttled. Excess traffic from an IP or account receives HTTP 429 with a 20-minute reset window. Caching responses for 24 hours is permitted and recommended.
Relaxed quota enforcement
ExchangeRate-API documents a relaxed enforcement policy where transient spikes slightly over quota are typically tolerated, but sustained over-quota traffic triggers the quota-reached error.
