Fly Io Rate Limits

Fly.io Machines API and CLI rate limits per organization.

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

It captures 3 rate-limit definitions, measuring requests_per_minute, machines, and concurrent.

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

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for throttled.
