## Authentication

All endpoints work without authentication. When no auth token is provided, an anonymous user account is automatically created and the response includes a `newAuthToken` field. Save this token to manage your content later.

To use a saved token, send it as a Bearer token:

```
Authorization: Bearer zagl_...
```

## Error Format

All error responses follow this structure:

```json
{
  "success": false,
  "error": "Error description"
}
```
