Face.com (Hebrew: פייס.קום) was an Israeli technology company that developed a platform for efficient and accurate facial recognition in photos uploaded via web and mobile applications.

In March 2010, Face.com opened an Alpha of their free REST API,[2] allowing third-party developers to integrate the Face.com facial recognition technology, algorithms, and database of tagged faces with their own apps and services.

The REST API gave developers free access to all of the platform's technology, with some applicable rate limits, while also offering white listing and premium licensing options.

With the API, developers could tag and recognize users from Facebook and Twitter, attach Face.com technology to their own index of images, or even mix and match facial recognition across photo sources, including Facebook, Twitter, Flickr, Picasa, and more.

[4] In 2011, a study conducted at the University of Massachusetts Amherst compared a portion of the Face.com algorithm, and found it to have a recognition rate of 0.91.
