# Set, extend, or clear a machine resource-expiry lease

`PATCH /v1/machines/{machine_id}`

Scope: `machines:write`. `ttl_minutes=0` clears expiry; values 5..10080 schedule expiry from now. Expiry destroys managed infrastructure. For an external machine it deletes only the Coasty registration and revokes device access/leases; caller-owned host and storage remain untouched.

## Request body

- UpdateMachineRequest
  - `ttl_minutes` union, required — 0 clears resource expiry; otherwise the value must be between 5 and 10080. Managed expiry destroys infrastructure; external expiry only revokes and deletes the Coasty registration, leaving caller-owned host/storage untouched.
    - 0
    - integer

## Response `200`

- UpdateMachineResponse
  - `machine_id` string, required
