# Restart a running machine

`POST /v1/machines/{machine_id}/restart`

## Request

- Base URL: `https://coasty.ai`
- URL: `https://coasty.ai/v1/machines/{machine_id}/restart`
- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer
- TypeScript: <https://skmtc.dev/coasty/apis/coasty-public-api/docs/v1/machines/:machine_id/restart/post.ts> (a function with typed inputs; its response is checked against the schema)

Managed: requests a reboot. External: logical dispatch restart only — increments the fencing generation, cancels pending commands, and marks the driver stale until it reconnects; Coasty does not reboot the caller-owned host.

## Response `200`

Restart requested.
