# Set Radio

`PUT /api/v1/companions/{companion_id}/radio`

## Request

- Base URL: `https://api.brumby.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.brumby.com/api/v1/companions/{companion_id}/radio`
- Auth: HTTP bearer

Body: `CompanionRadioUpdate` (`{netid, aes_key_hex}`). Validated here rather than
by FastAPI so a refusal never echoes the key back (FastAPI's 422 carries `input`).

## Path parameters

- `companion_id` string, required

## Request body

- object

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
