In simple English
This tool finds and verifies contact details like emails and job titles by querying multiple data providers one after another. If the first cheap provider finds a match, it stops and saves money. If not, it moves down the list to the next provider until it gets a result. You provide your own API keys for the services you want to use. It costs nothing to download and run, but you pay each provider for the credits you use.
