FullContact is an API that keeps contact information current. Developers can easily tap into FullContact’s database of more than 100 million contact records to quickly turn partial, out-of-date contact records into fresh, complete contact records. They use a crowdsourcing model to update the contact information, only share contact information that’s publicly available on the web, and unlike competitors like Plaxo and Jigsaw, they allow any software application to leverage their contact database via their API.
