Leah Culver, the lead programmer of Pownce, has informed us that the messaging/social networking service will release a more complete API this Friday, one with substantial improvements over the first version released late last October.
This second version will include the ability to post notes and replies, fetch private and friends-only notes (in addition to public messages and user information), and upload and download files. OAuth support will also be rolled out, allowing users to protect their Pownce data when using API-based services. Services built on the API will be publishable in a Pownce directory where users can find them more easily.
Culver says that API 2.0 is powerful enough that developers could recreate the official Pownce AIR client if they were so inclined. Pownce is already speaking with several partners who have shown an interest in using the new API, including Flock who plans to integrate Pownce into its people sidebar so you can see friends’ messages and post messages while browsing.
SocialThing! and Mahalo also plan to use Pownce’s new API. SocialThing!, a social activity aggregator launching this March, will feature the ability to send messages to friends on Pownce in addition to other sites such as Flickr, Facebook, Twitter, del.icio.us, and YouTube. Mahalo currently relies on a hack to allow website sharing to Pownce through its Share Firefox toolbar; access to this new API will replace that hack.
Culver will be at FOWA Miami this Friday to officially launch the new API. She’ll be speaking there about websites as services and the importance of solid APIs.
