API Commons Governance Rules
The 776 rules of the openly-governed API Commons catalog, written in the ruleset format specified by OpenLint. Each rule is a single, testable assertion about an API artifact, spanning 12 artifact types from OpenAPI and AsyncAPI to APIs.json, JSON Schema, Arazzo, MCP, and agent skills. Rules ship at info by default — educate first, then raise to warn or error to enforce. Expand any rule for its full definition; each one has its own link to share.

Run these rules
The same catalog runs everywhere — on the command line, in the browser, over HTTP, from an AI client, or as a CI gate. Bundle rules by experience ruleset, or extend the built-ins.
CLI
Lint locally or in CI with the OpenLint CLI (or Spectral). Download an experience ruleset and run it.
npx openlint lint api.yaml --ruleset <ruleset>Browser validator
Lint in the browser — no install — with AI fixes and utilities.
