# Sign out and clear session cookies

`POST /auth/sign-out`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/auth/sign-out`
- Auth: one of:
  - none
  - API key in cookie `mnemom_session`
  - HTTP bearer

Revokes the refresh token upstream and clears `mnemom_session` + `mnemom_mfa_pending`. Idempotent and anon-callable by design — calling it without a session returns 200 + no-op cookie clear, so a logged-out client can safely re-issue the call without observing a 401.

## Response `200`

Cookies cleared.

- object
  - `ok` boolean

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Cross-origin write refused (`cross_origin_rejected`). A state-changing request that carries the browser session cookie must come from a first-party origin (`Origin`, or failing that `Referer`) and must not send a form-style body (text/plain, urlencoded, multipart) the operation does not declare. Bearer and API-key callers are never subject to this check.
- `429`: Rate-limit exceeded. The global per-IP limiter (100 requests/minute, applied to every `/v1/*` route) rejected this request. Back off until the window resets — `Retry-After` carries the cooldown in seconds and `X-RateLimit-Reset` the absolute reset time.
- `500`: Server error — request was well-formed but the server failed to fulfill it. Typically a downstream dependency (DB / RPC / external API) returned an unexpected error.
- `503`: An upstream dependency is currently unavailable. The request was not processed; retry after the cooldown window.
