How to Validate a Domain Name in Python

Domain validation, while useful, is a difficult feature to create from scratch. We will be simplifying this process immensely by applying an easy-to-use API to the problem at hand.

Install the client we need first.

pip install cloudmersive-validate-api-client

Now we are able to call the domain_check function, which takes our domain name as an argument.

from __future__ import print_function
import time
import cloudmersive_validate_api_client
from cloudmersive_validate_api_client.rest 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 \"cloudmersive.com\".  The input is a string so be sure to enclose it in double-quotes.
try:
# Validate a domain name
api_response = api_instance.domain_check(domain)
pprint(api_response)
except ApiException as e:
print("Exception when calling DomainApi->domain_check: %s\n" % e)

OK, you’re done! No more problems with invalid domains!
