If you're interested in creating a great genome app, visit https://api.23andme.com. Developers who'd like to use the API must first apply for authorization from 23andMe, describing the proposed application and the information it will request from end users. While 23andMe will not endorse or promote specific applications, 23andMe will individually evaluate applications on a case-by-case basis. 23andMe customers can decide for themselves whether to grant access to an app that uses the API. View the current API terms here.
The Personal Genome API is a work in progress and is available for free during this early access period. The scope and terms of the API will evolve as we gather feedback and learn from developers, users and others.
We are excited to welcome third-party developers as our partners in building new features for personal genomes. There is no app too small — so if you'd like to create some "genetic code", we invite you to apply!
