I'm a free user, I think it has something to do with localbitcoins.com not being white listed. Anyone knows it this could be solved with a hacker account? Thanks

If you provide a link to the API's documentation, then the staff can add it to the whitelist.

Yes, it would almost certainly be solved with a hacker account -- they have unrestricted access to the external Internet, so the only case in which it would not work would be if localbitcoins were blocking access from our servers, which is unlikely (though not completely impossible).

However -- we do have localbitcoins.com on the whitelist already, so I think the problem is the specific code you're using to connect to it. Free accounts need to use a proxy server to make their outbound connections; if you use the requests library instead of using urllib3 directly, then it will automatically pick up the proxy details and do it all for you transparently.

Thanks for your answers, I think the problem is I'm not using the official library, I'm using this one that is python 3 compatible: https://github.com/6ones/lbcapi3

The library that you use needs to support using a proxy for the connection and you need to configure it to use the proxy. Check the docs for the library to see if it supports it and how to configure it and check http://help.pythonanywhere.com/pages/403ForbiddenError/ for the details.
