My guess is that you are using free hosting that has anti-bot protection on your hosting to prevent API use.
Your API is returning an html response as part of its bot protection. The response is actually some code that needs to run on your client before the server will allow it to access the API.
The solution is to switch to another paid hosting provider that doesn’t place such restrictions on your Wordpress site.
This is not a Make problem, it is an issue with your web hosting provider.
