    ## Authentication


    Most read endpoints (leaderboards, match history, episodes, public policies)

    work without auth. Submitting policies or accessing your own data requires

    a Bearer token:


    ```

    Authorization: Bearer <your-token>

    ```


    To get a token, install [cogames](https://pypi.org/project/cogames/) and
    run:


    ```bash

    cogames auth login

    ```


    A `401` response means no token was provided. A `403` means the token

    is invalid or expired.


    ### Verify your token


    ```bash

    curl -H "Authorization: Bearer <your-token>" \
      https://softmax.com/api/observatory/whoami
    ```


    Returns `{"user_email": "you@example.com"}` on success.
