Code before:

        if not api_url_match:

            None,
        )
        if not channel_json:
            raise ExtractorError(f'Channel "{faulio_url}" not found in API')

Review comment (suggestion):
Let's prepend the domain to have unique IDs
```suggestion
        domain = urllib.parse.urlparse(api_base).hostname
        return {
            'id': f'{domain}:{video_id}',
```
