Originally posted by Sa7cez September 4, 2024 Please add new Vercel Challenge bypass feature.

The first request from the site returns a 429 response with the cookie "x-vercel-challenge-token".

Then the js script and solver are loaded, which send the token and the response "x-vercel-challenge-solution".

After that, the server returns cookies that are linked to a specific browser fingerprint and allow further requests to be sent.
