Fern Api Rate Limits
Fern does not publish fixed numeric HTTP rate limits for its hosted Ask Fern REST API. Practical usage is governed by plan-based AI credits rather than a per-minute request cap - the Hobby tier includes 250 AI credits per month and the Team tier 1,000, with Enterprise negotiated. SDK generation and docs generation run through the open-source `fern` CLI, so their throughput is bounded by your own CI/CD and local compute rather than by a Fern-imposed limit. Publishing generated SDKs is ultimately subject to the rate limits of the downstream registries (npm, PyPI, Maven) and of GitHub.
Fern Api Rate Limits is the machine-readable rate-limit profile for Fern on the APIs.io network, conforming to the API Commons Rate Limits specification.
It captures 4 rate-limit definitions, measuring requests, credits, runs, and publishes.
The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.
Tagged areas include SDK Generation, API Documentation, Developer Tools, Rate Limiting, and Quotas.
