OneAPI, as defined by the telecom^[2] industry—led by GSMA and the Open Mobile Alliance (OMA)—is a set of standardized and lightweight Web-friendly application programming interfaces (API) for communications service providers (CSPs) to use to expose their networks. Building on OneAPI version 2.0 specifications, the current OneAPI specifications are at version 3 beta (published from February to April 2012).

Any mobile operator or service provider is able to implement and use OneAPI. OneAPI is intended to complement existing client-side and Web APIs^[clarify] and not replace it, by providing access to network capabilities and information, regardless of operator.
