# End Session

`GET /oauth2/logout`

## Request

- Base URL: `https://pozeidon.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://pozeidon.ai/oauth2/logout`
- Auth: none declared

RP-initiated logout (OIDC). Clears the pozeidon SSO session cookie so the
next /oauth2/authorize prompts a real login (instead of silently re-issuing
a code). Redirects to `post_logout_redirect_uri` ONLY when it shares an
origin with the calling client's registered redirect_uris — else falls back
to pozeidon's own login. The cookie is cleared regardless of the target.

## Query parameters

- `client_id` string, nullable
- `post_logout_redirect_uri` string, nullable

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
