# Stream Events

> Subscribe to a Server-Sent Events (SSE) stream of agent lifecycle events.

The stream replays retained historical events after the cursor, then
delivers live events as they occur. Events are delivered at-least-once;
clients should deduplicate by event `id`.

Use the `after` query parameter or `Last-Event-ID` header to resume
from a previous position. If the cursor is older than the earliest
retained event, the server returns `410 Gone`.

  title: Miru Agent API
  description: >-
    The API between the Miru Agent and any external client living on the same
    device as the Miru Agent. On Linux the agent serves it over the Unix socket
    `/run/miru/miru.sock` with no authentication. Over loopback TCP, which is on
    by default on Windows at `127.0.0.1:6478`, every route requires
    `Authorization: Bearer <token>`. Clients read the port and token from the
    agent's discovery file, `%ProgramData%\Miru\device-api\device-api.json` on
    Windows; the token changes every time the agent starts.

      feat(device): rename component_slug to component in
      CreateCalibrationRequest (#359)


      <!-- claude-projects-attribution: {"github_login":"miru-agents"} -->

      _Requested by **bens-agent** · [project

      thread](https://claude.ai/code/project/chan_015imaa8aZrnubYZcZCvjeHx?thread=cmsg_015imaa8aZrnubYZcZCvjeHxMkwTnPSSvfAHZA9NT4YaSe)_


      ## Summary


      Renames `CreateCalibrationRequest.component_slug` to `component` in the

      Device API's `POST /calibrations`. #339 already renamed it this way in

      the agent API. The field is still required and still holds the

      component's slug, so it now matches `role` and `aspect`, which are slugs

      without a `_slug` suffix. The description uses the same wording as the

      agent API's.


      The published `device/v0.2.3` release is being removed, so it can be

      re-released from this change.


      ## Changes


      - `apis/apps/device-server/components/requests/calibration.yaml`: the

      field and its `required` entry are renamed, with a new description.

      - `apis/apps/device-server/openapi.gen.yaml`: regenerated.


      ## Not in this PR


      - The agent's Device API handler must accept `component` before an agent

      release serves this version.

      - The docs follow in mirurobotics/docs#269.


      ## Test plan


      - `./scripts/regen.sh` and `./scripts/lint.sh` pass.
