How should we pass URL having query parameters?

Edit -
example URL is
https://www.amazon.com/s?k=Mobile+Pixels+Duex+Pro+-+Upgraded+2.0+Portable+Monitor+for+Laptops+-+12.5%22+Full+HD+USB+Screen+Plug+and+Play

To send it to superstack i converted it into
http://api.scrapestack.com/scrape?access_key=1234&url=https://www.amazon.com/s?k=Mobile+Pixels+Duex+Pro+-+Upgraded+2.0+Portable+Monitor+for+Laptops+-+12.5%22+Full+HD+USB+Screen+Plug+and+Play&ref=nb_sb_noss&keep_headers=1

But it's giving me error
b'{"error":{"code":"validation_error","status":422,"context":[{"url":{"type":"invalid_url","message":"The url is not valid"}}]}}'
