I wanted to ask you for help with a topic, I am trying to create an API to use in Discord, but I have a problem, this app (discord) only reads JSON, and my site is HTML,

here I add some things:

1. my prototype as it should be: https://silly-brioche-2508ee.netlify.app
2. example of a working API: https://api.popcatdev.repl.co/instagram?user=example
3. HTML file: https://cdn.discordapp.com/attachments/966128567819845632/967547957186539611/index.html

I need to adapt MY concept to JSON, help me? thx :)
