Your JavaScript code can call remote APIs from the page. Here are some useful functions.


To call the GPT API from OpenAI, define the API key and prompt, and then:

AB.callGPT ( apikey, prompt, function ( reply ) { ... } );
    // The reply is the 'payload' extracted from the full API return data.
    // You define a function to do something with the reply. 
    // The full API return data is saved in AB.apidata 
If you want to write a customised API call, look at the code for this World:

JavaScript page to chat with a GPT model. Calls OpenAI API. User needs to enter API key.


JavaScript can fetch resources (like images) from any site on the Internet if the site is CORS enabled. For sites that are not, you can go through a CORS proxy. Here is a handy function to get a CORS-enabled URL for your resource, using

AB.cors ( url );       // return CORS-enabled URL for this resource 

So fetching url into your JS graphics World may fail, but fetching AB.cors ( url ) may work.
