Function Health Rate Limits

Function Health does not publish a public or developer API, so no API rate limits, quotas, or throttling policies are documented. The closest operational limits are product cadence limits on the consumer membership (lab testing scheduled twice per year, with on-demand add-on tests) rather than request-per-minute API throttles. There are no documented HTTP rate-limit headers or 429 throttling responses to reconcile.

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

It captures 1 rate-limit definition, measuring lab_rounds.
