VK api now asks for a token even in order to get a person's avatar?

Question

In contact with

I'm trying to get my own avatar like this:

https://api.vk.com/method/users.get?fields=photo_200&user_ids=199334161

I get this:

{"error":{"error_code":5,"error_msg":"User authorization failed: no access_token passed.","request_params":[{"key":"oauth","value":"1"},{"key":"method","value":"users.get"},{"key":"fields","value":"photo_200"},{"key":"user_ids","value":"199334161"}]}}

As for me, it looks crazy, especially considering that the description of the method says that the token can be used, but not necessary. What am I doing wrong?
