title: Public APIs — Mobile Client Growth API
description: 'API reference for the Public APIs Flutter mobile app. Includes anonymous device auth, email/password account linking, profile management, bookmarks, folders, discovery, categories, search, and legacy JSON endpoints.
## Authentication
Bearer-protected endpoints require:
```
Authorization: Bearer
```
Tokens are obtained via `POST /v1/auth/anonymous` or `POST /v1/auth/login-email`.
Public endpoints (no token required): `POST /submit`, `POST /v1/apis` (auth optional, enables submission attribution), `POST /v1/auth/anonymous`, `POST /v1/auth/refresh`, `POST /v1/auth/revoke`, `POST /v1/auth/login-email`, `GET /v1/recently-added`, `GET /v1/recommend` (auth optional, personalizes with bookmarks), `GET /v1/apis/{slug}`, `GET /v1/apis/{id}/alternatives`, `GET /v1/trust-scores/{id}`, `GET /v1/apis/compare`, `GET /v1/change-feed`, `GET /v1/use-case-collections`, categories (unversioned and `/v1` aliases), `GET /search`, `GET /metadata`, `POST /track`, and `POST /admin/v1/contact-messages`. Every other `/v1/*` operation requires a Bearer token.
## Account Types
- **Anonymous**: Device-only, no email. Data tied to device fingerprint.
- **Email-linked**: Has email + password. Can login from any device. Data merges on link.
## Token Lifecycle
- **Access token**: 15 minutes, used for API requests
- **Refresh token**: 30 days, used to rotate access tokens
- Refreshing a token invalidates the old one (single-use rotation)
- Revoking deactivates all tokens for a device'
