Validating Active ShareFile Accounts with Clay: A Cost-Effective Guide

Looking for help validating if a company has an active account for a web service where their company name would be part of the subdomain. How would you most cost effectively and accurately use Clay to execute a prompt/enrichment like is described? Thank you! The mission is to determine if /company name has an active ShareFile account. For example, if your ShareFile account’s URL is “mycompany.sharefile.com”, you would enter “mycompany”. How would you create a prompt to create a “true / false” output, where after entering in /company name with spaces removed into the subdomain part of the URL, the next page to load in the sequence will create one of two outcomes: 1) an active company ShareFile account exists and ready to enter credentials to login. This page would include this wording “Welcome! Enter your details to sign in to ShareFile” or 2) no active company account can be found for the entered domain and it re-directs to the page where the user has to manually enter the subdomain name (i.e. https://secure.sharefile.com/Authentication/Login#/StartViaSubdomain)
