How to lookup domain WHOIS in Python

Today’s tutorial will cover looking up WHOIS for a domain using a Cloudmersive API. Let’s dive straight in. First up, use pip installer to install our Validate API Client:

pip install git+

Second, simply call the function domain_post, and that’s about it!

from __future__ import print_function
import time
import cloudmersive_validate_api_client
from import ApiException
from pprint import pprint
# Configure API key authorization: Apikey
configuration = cloudmersive_validate_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'
# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
# configuration.api_key_prefix['Apikey'] = 'Bearer'
# create an instance of the API class
api_instance = cloudmersive_validate_api_client.DomainApi(cloudmersive_validate_api_client.ApiClient(configuration))
domain = 'domain_example' # str | Domain name to check, for example \"\". The input is a string so be sure to enclose it in double-quotes.
# Get WHOIS information for a domain
api_response = api_instance.domain_post(domain)
except ApiException as e:
print("Exception when calling DomainApi->domain_post: %s\n" % e)

Seriously, it’s that easy. Let’s look at an example result using “”:
