udefn provides a set of APIs that allow external applications to send and receive SMS text messages to and from their users, respectively. The goal of udefn is to offer publishers/developers a service that would be very useful to mobile users readily.
udefn supports this service by attaching advertisements in the second 1/2 of each message sent to mobile users. You earn points everytime your bot responds to users queries. If you wish to brand your responses and not have any advertisements inserted, you can setup your bot to be a charge-bot. In this case, instead of you earning points, you will be charged points for each user query. You get access to complete message body and no advertisements will be inserted.
Getting started is easy. Visit FAQ pages to see for yourself.
