# Cookie-aware whoami

`GET /auth/session`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/auth/session`
- Auth: API key in cookie `mnemom_session`

Minimal whoami endpoint. Returns `{ user }` when the `mnemom_session` cookie is valid; returns 401 otherwise. Preferred over `GET /auth/me` for cookie-only browser sessions — `/auth/me` is bearer-only and preserves its legacy response shape unchanged.

## Response `200`

Authenticated session.

- object
  - `user` User: Supabase user shape. Fields beyond `id` and `email` are passthrough.
    - `id` string, uuid
    - `email` string, email
    - `app_metadata` object
    - `user_metadata` object

## Other responses

- `401`: Authentication required
- `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.
