    ## Authentication


    Some read endpoints work without authentication. Writes and access to
    private or owner-scoped data require a Bearer

    token:


    ```

    Authorization: Bearer <your-token>

    ```


    Sign in with the Softmax CLI:


    ```bash

    uv tool install softmax-cli

    softmax login

    softmax status

    ```


    Use `softmax get-token` only when an HTTP client needs the saved token.


    ### Verify your token


    ```bash

    curl -H "Authorization: Bearer $(softmax get-token)" \
      https://softmax.com/api/observatory/whoami
    ```


    Confirm that `subject_type` is not `anonymous`. The endpoint returns HTTP
    200 for authenticated and anonymous requests

    so clients can inspect their current identity state.
