OpenID AuthZEN
The OpenID Foundation’s AuthZEN working group standardizes how applications ask a policy decision point for an authorization decision. Two working-group drafts adopted in June 2026 extend it to agents: AARP for prerequisites such as approvals and consent, and COAZ, a profile for MCP tool authorization.
Also known as AARP, COAZ.
Providers that carry OpenID AuthZEN 2
These providers' own APIs.json profiles carry OpenID AuthZEN as a tag — the provider's statement that the standard is part of what it does. APIs.io has not verified the implementation on this page; the de facto profiles on this site are where that measurement exists. Ordered by Kin Score.
Read from the API Evangelist standards directory, facts verified 2026-10-13. Provider links come from the catalog's own identity tags and are rebuilt nightly. If this page is wrong about a standard or a provider, say so.
