Send a requests to a magnet links shortener which doesn't have APIs

[Ascalon]

Wow this is incredible many many thanks!
Thanks to your suggestion "look what send over network" I tried to play with the browser DevTools and inside the Network tab I found the request url, the payload and the request headers. But I found many more request headers than the ones you put insede the python dictionary (see image below), so may I ask you how to choose what are the ones needed to be put in the dictionary?
Again thank you so much
