Continuing its effort to turn its platform into a revenue generating service, Pinterest is enhancing its API platform to give marketing companies more insight. 

TechCrunch reported today that Pinterest is preparing to announce a new initiative that will allow businesses to gain a better understanding of Pinterest trends, along with the improved API platform. The new service is currently offered to a limited number of marketing technology firms, including Salesforce, HootSuite, Spredfast, Percolate, Piqora, Curalate and Tailwind.

The API is Pinterest's first effort to allow third parties to build over its services. The company will continue to offer its free analytics service.

By giving companies a more comprehensive understanding of Pinterest trends -- which images are most popular, which are driving the most traffic and which have been shared, or "repinned," the most -- Pinterest thinks companies could design more effective marketing campaigns and facilitate greater customer engagement.
