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 prioritized profiling is the fast lane if you would rather have it done for you.

Scored on rubric v0.17.2 across 27,504 providers · lists rebuilt 2026-09-01 · capped at the top 500 per page.
