# Scale a Compute instance to a new Instance Type

`PUT /instance/{id}:scale`

## Request

- Base URL: `https://api-ch-gva-2.exoscale.com/v2`
- URL: `https://api-ch-gva-2.exoscale.com/v2/instance/{id}:scale`
- Auth: none declared
- TypeScript: <https://skmtc.dev/exoscale/apis/exoscale-api/docs/instance/:id:scale/put.ts> (a function with typed inputs; its response is checked against the schema)

## Request body
