Codespaces machines
Use the REST API to manage availability of machine types for a codespace.
About Codespaces machines
You can determine which machine types are available to create a codespace, either on a given repository or as an authenticated user. For more information, see "About machine types."
You can also use this information when changing the machine of an existing codespace by updating its machine property. The machine update will take place the next time the codespace is restarted. For more information, see "Changing the machine type for your codespace."
