Apilayer Rate Limits

Apilayer Rate Limits is the machine-readable rate-limit profile for APILayer on the APIs.io network, in the API Commons Rate Limits shape.

It captures 8 rate-limit definitions, across the Free, Basic (ExchangeRate.host / Exchange Rates API), Professional / Professional Plus, Business, and Standard (ipapi) tiers, measuring requests and lookups.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, serviceUnavailable, and caveat.

Tagged areas include API Marketplace, API Catalog, API Discovery, Developer Tools, and SaaS APIs.

Policies

Overage, not cut-off
Paid tiers meter past the quota at a published per-request price rather than hard-stopping, so exceeding the plan costs money instead of returning 429.
Backoff
No Retry-After is sent, so a client must choose its own backoff. Distinguish rate_limit_reached (retry shortly) from usage_limit_reached (do not retry this month).
Scope
Limits attach to the per-product access key, not to the APILayer account. Each subscribed product carries its own independent quota.
