Now, you can download Mobile Recharge API from the API tab above.
There are two documents : API.doc which gives details of the the http based API and mapping.xls which maps the operators and circles to specific ID’s.
This is the first time in India that mobile recharge API is available for free. And openly.
The API can be used to develop applications for social networks like facebook and twitter or to create your own mobile recharge site or contests where you can sponsor free talk time.
