Fusio Rate Limits

Fusio publishes no fixed numeric rate limits, because it does not operate the API - the operator does. What Fusio publishes instead, and what actually matters to an agent, is the RUNTIME SIGNAL: the exact response headers a Fusio-served API emits, the status code on exhaustion, and the allocation model that decides which limit applies. Those are recorded below and they are the same on every Fusio instance in the world.

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

It captures 1 rate-limit definition, measuring requests.

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

The profile also includes response codes documented for throttled and quotaExceeded.

Tagged areas include API Management, Open Source, Rate Limiting, and Throttling.

Limits

Reference instance anonymous limit per-ip

900/unknown
Observed live on the project's own reference instance, which does have a rate allocation configured. The window is not recoverable from the response because Fusio emits no reset or policy header, and the 15-minute Retry-After is a fixed implementation constant rather than the configured timespan. This is the demo instance's own configuration, not a Fusio default - a fresh install ships no rate allocation at all.
