Is downloading/installing the PHP API library required to use the API?

Is Composer the only way to install that PHP API library?

[Is there a fix for this bug?](https://forum.mautic.org/t/why-does-composer-require-willdurand-oauth-server-bundle-0-0-3-in-mautic-4/20835)

Is the [API documentation](https://developer.mautic.org/?php#rest-api) still valid for Mautic 4?

Is there a ‘hello world’ code example for the API anywhere?
