steam.bhvr.api refuses request to collect Data.....

Is there a possibilty someone could teach me reading https/http request to parse current shrine of secrets/news of steam.bhvr.api? Im Working on a stats page but the Api refuses my requests even with api token.... -.- its always crashing with some sort of language code.

i am searching too this, i cant login for get shrine, as i see they have removed the "guest" access.
If you find any information, let me know.
