Greasy Fork

Perfect!
I was just about to make it myself, but then I saw it already existed.

I am glad this work, at least this way I don't have to install their old and outdated extension https://chromewebstore.google.com/detail/webtorio-watch-torrents-o/ngkpdaefpmokglfnmienfiaioffjodam

Doesn't work on https://www.limetorrents.lol/Godzilla-x-Kong-The-New-Empire-2024-1080p-AMZN-WEB-DL-DDP5-1-H-264-FLUX-torrent-18472258.html

working code

(function() {
'use strict';
document.addEventListener('click', function(e) {
var clickedEl = e.target.closest('a');
if (!clickedEl || !clickedEl.href.startsWith('magnet:')) return;
e.preventDefault();
location.href = 'https://webtor.io/' + clickedEl.href.match(/[A-F0-9]{40}/gmi)[0].toLowerCase();

})();

thank you! I just updated with your code

Look at the JavaScript fetch example here https://rapidapi.com/paveltatarsky-Dx4aX7s_XBt/api/webtor/playground/apiendpoint_f092fd42-e8c5-437f-ac9e-049869ce46d7

You need to add an API Key.
Right now it fails if the torrent has never been magnetized before by them, and this happens kind of often...
