Google pagerank api returns 403 to some urls

Google APIs Call Pagerank URLs. in this example, "spiegel.de" works:

http://toolbarqueries.google.com/tbr?client=navclient-auto&features=Rank&q=info%3Aspiegel.de&num=100&filter=0&ch=79909496714

Trying to use a different "hotpress.com" URL, all other parameters are untouched, showing a 403 error page!

http://toolbarqueries.google.com/tbr?client=navclient-auto&features=Rank&q=info%3Ahotpress.com&num=100&filter=0&ch=79909496714

Why?

You need to calculate the hash correctly, I use the code from this place:

What I adapted a little to get PR information for my project in the search engine. There are also several other scripts there if you are just Google.

Google returns an error because the URL q value is checked against the hash / checksum value ch .

You need to calculate the hash / checksum ch for each q request.

I don’t know which hash algorithm Google uses here, but the Internet believes that it may be Jenkins or some of its versions.
