# Paskia API

Use these tables when integrating Paskia authentication into your app.

### Browser URLs (user-navigable)

| Method | Path | What it is for | Notes |
|---:|---|---|---|
| GET | `/` | User profile UI | On app hosts you can also use `/auth/` |
| GET | `/auth/` | User profile UI (legacy entry) | Alternative entry point for `/` |
| GET | `/admin/` | Admin UI | Legacy entry: `/auth/admin/` |
| GET | `/{token}` | Reset / registration / device-add UI | Legacy entry: `/auth/{token}`; invalid tokens return `404` |
| GET | `/auth/restricted/` | HTML UI used by the auth-forward flow | Typically shown via `/auth/api/forward` on failures |

### App HTTP API: `/auth/api/*`

| Method | Path | Used for | Inputs / outputs (high level) |
|---:|---|---|---|
| POST | `/auth/api/validate` | Validate session cookie; optionally renew | Query: `perm` (repeatable). JSON response includes `valid`, `user_uuid`, `renewed` |
| GET | `/auth/api/forward` | Reverse-proxy auth check (Caddy/Nginx) | Query: `perm` (repeatable), `max_age`. Success: `204` with `Remote-*` headers; failures: `4xx` JSON or HTML depending on `Accept` |
| POST | `/auth/api/set-session` | Turn a Bearer session token into a cookie | Header: `Authorization: Bearer <session_token>`; sets cookie |
| POST | `/auth/api/logout` | Clear cookie and delete session (best-effort) | Returns JSON message |
| GET | `/auth/api/settings` | Fetch runtime settings for clients | Returns RP info + base paths + session cookie name |
| GET | `/auth/api/token-info` | Validate reset token and fetch minimal metadata | Query: `token=<token>`; invalid/expired returns `404` |
| POST | `/auth/api/user-info` | Fetch user info for UI | Either session cookie, or `reset=<token>` for reset flows |

See [Headers.md](Headers.md) for the `Remote-*` header contract used by `/auth/api/forward`.

### User account HTTP API: `/auth/api/user/*`
