  title: Bernstein Task Server Orchestrator Holds API
  description: 'Bernstein REST API - the open-source governance layer for AI agents, one git worktree per task.


    ## Authentication


    Authentication is ENABLED by default. Include a Bearer token in all requests:


    ```

    Authorization: Bearer

    ```


    To run without auth (development only), set `BERNSTEIN_AUTH_DISABLED=1` - this logs a loud warning and passes every request through.


    Public endpoints (no auth required): `/health`, `/health/ready`, `/health/live`, `/ready`, `/alive`, `/.well-known/agent.json`, `/docs`, `/openapi.json`, and the auth-flow endpoints (`/auth/login`, `/auth/oidc/callback`, etc.).


    Webhook and hook endpoints (`/webhook`, `/webhooks/*`, `/hooks/{session_id}`) authenticate via HMAC-SHA256 signatures - they do NOT accept Bearer tokens.


    ## Base URL


    Default: `http://127.0.0.1:8052`. Override with env vars `BERNSTEIN_HOST` and `BERNSTEIN_PORT`.


    ## Error Format


    All errors return JSON with a `detail` field:


    ```json

    {"detail": "Task not found: task-xyz"}

    ```


    | Status | Meaning |

    |--------|---------|

    | 400 | Bad request (validation error) |

    | 401 | Unauthorized (missing/invalid token) |

    | 403 | Forbidden (IP not in allowlist) |

    | 404 | Resource not found |

    | 409 | Conflict (task already in terminal state) |

    | 429 | Rate limited - respect the `Retry-After` header |

    | 500 | Internal server error |'
