The Prosper iOS SDK by Prosper allows users to apply for a loan within an application. To implement the API, developers will work with Borrowers SDK, which contains AFNetworking, AFOAuthO2Manager, and Google Maps.
Of all the markets being impacted by the booming API economy, perhaps none has seen as much activity and innovation as the payments space. The past several years have seen the launch of a number of disruptive and successful API-centric upstarts, including Stripe and Balanced. Meanwhile, entrenched players like PayPal and Verifone have responded with new offerings of their own.
