Writes and access to private or owner-scoped data require a Bearer token: ``` Authorization: Bearer ``` 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. version: 1.0.0 servers: - url: https://softmax.com/api/observatory security: [] tags: -
