Openfda Rate Limits
openFDA enforces a single platform-wide rate-limit policy across every dataset endpoint. Without an API key, callers are throttled by source IP; with an API key, the per-minute ceiling is unchanged but the per-day ceiling rises by two orders of magnitude.
Openfda Rate Limits is the machine-readable rate-limit profile for openFDA on the APIs.io network, conforming to the API Commons Rate Limits specification.
The profile also includes response codes documented for throttled.
Tagged areas include Government, Healthcare, and Rate Limiting.
