I see lot of websites popping up which offer an API which can be used to recharge mobile credit or pay dth/post paid bills. How do these APIs work? Do they interface with other web services which merchants expose? Do billers like Airtel have an exposed API which these companies use?

Yes. They have an API, but it's not public and you will need license to use. You need to be a registered company and have some XXXX amount invested/worth of company.
