How to resolve blockchain DNS using Python Requests

Question

There are certain blockchain domains that are resolved only by blockchain DNS resolvers.

If you try to open such a link in a browser, it won’t get resolved.

However, if you install a compatible browser plugin that supports blockchain DNS, the site will open smoothly.

I want to scrape some data from this site using Python Requests (browserless) and have no idea how to resolve such blockchain domains. Any help would be highly appreciated.

You could use one of their publicly available apis to resolve the domain and obtain an ip. You'll find a list of api urls in the Firefox or Chrome addon script, in common.js.
A python example,

import requests
from random import choice

def domain_ip(domain):
    '''Uses bdns api to resolve domain names'''
    domain = domain.split('/')[2] if '://' in domain else domain
    apis = ['https://example.com/r/', 'https://example.us/r/', 'https://example.bz/r/']
    api = choice(apis)
    r = requests.get(api+domain)
    if r.status_code == 200:
        ip = r.text.splitlines()[0]
        print("Domain: {}  IP: {}".format(domain, ip))
        return ip
    else:
        print('HTTP Error: {}'.format(r.status_code))

ip = domain_ip('http://example.com')
if ip:
    r = requests.get('http://'+ip)
