    # Seamo Authentication API

    The Seamo Auth Server provides authentication and user management services for the Seamo platform.

    ## Features

    * User registration and authentication
    * Project management
    * Journal management
    * Access control

    ## Authentication

    Most endpoints require authentication. Use the /api/auth/token endpoint to obtain access tokens.
