REST API endpoints for Codespaces machines

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 Changing the machine type for your codespace.

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.
