Agent-readiness dimension

Rate-Limit Signaling

7 of 139 agent-readiness points 5.0% of the agent scoregraded — partial credit rate_limit_signal

Rate-limit behaviour is documented as machine-readable data. An agent needs to know when to back off; "you will get a 429 eventually" is not something it can plan against. Full credit requires the API to surface live rate-limit state in RESPONSE HEADERS, which is what an agent reads mid-run — documented limits tell it the ceiling, headers tell it where it is.

Move this number. Every provider in the catalog is profiled from a public repository at github.com/api-evangelist/<provider>, and each check above names the exact artifact it reads. Publish the artifact, open a pull request, and the next scoring run picks it up — no gatekeeping and no fee. The full rubric is at apis.io/rating/, and the Influence plan is the fast lane if you would rather work your own listing through the API — remediation, projections and re-check requests.

Scored on rubric v0.23.0 across 28,886 providers · lists rebuilt 2026-10-08 · capped at the top 500 per page.
