    • The name "create_project" says "create": a word for a change.
    Description, as the server wrote it
    Create a real hosted backend (a REST API with a persistent database) in one call, with no account or API key.

Returns a manage key, a read-only public key, a starter "products" collection, the base URL and a claim_url.
