I've created this crawler for Valor. Please check if it's ok. I try to take in count the coments on @lucasmachadorj pull request.

It might be a good idea to break this line to make it more readable. PEP8 suggests 72 with a maximum of 79. I like to follow that whenever possible.

I think that, apart from the really small issues I pointed out in line comments, the code looks good and we should merge it.

Also, another really important thing: please use 4 spaces instead of tab. I have no real problem with tabs, but mixing spaces and tabs are a bad idea, and our entire code base is using spaces. If you use vim you can use spaces by adding

    set tabstop=4
    set shiftwidth=4
    set expandtab

To your .vimrc.

You don't need to import re nor pandas. It's a good idea to remove these imports.
