How to find out the artist's yandex id?

Question

ruby

Hello everyone) Guys, there is such a task - you need to find the yandex id of the artist. Wrote a program in ruby ​​and seems to find it. But this only works for two performers. And then Yandex blocks. And what do we need for 500 performers? I tried to specify UserAgent, Accept-Encoding and other request headers in the request. And Yandex no longer blocks. But in the output there is only some incomprehensible character. In general, I do not know how to solve the problem. Please help)
