Back in June, the photo-sharing service allowed developers to access photos and favorites from a user’s contacts in their applications using some of Flickr’s nifty PuSH API methods.
As Flickr’s “nils” noted in the Flickr developer blog, those methods were “pretty neat, but that barely scratches the surface of stuff that happens on Flickr that people might be interested in. So we added some more stuff to subscribe to.”
The new APIs make use of Pubsubhubbub (for instant notifications when something is published — say, a new photo) and allow developers to grab a lot more interesting data for their users, including:
Photos of you
Photos of your contacts
Your photos and favorites
Photos from a specific area (using geodata)
Photos with a certain tag or tags
Images from the Flickr Commons
And, of course, photos and favorites from your contacts
When grabbing photos from the Commons, you can specify a particular institution or institutions to pull from — for example, you could just get pics from the Smithsonian and the White House. Or, you could scrape all photos and updates from the Flickr Commons in real time.
As for geodata, you can specify an area using a point and radius or a set of WOE IDs, the subscribe to images from that area. This would be handy for getting a real-time stream of photos of tourists “holding up” the Leaning Tower of Pisa, to name a terrible example that should never be implemented by anyone.
Etsy developer Kellan Elliot-McCrea was kind enough to post about how to get started with the new APIs, including some lovely PHP snippets.
Flickr will be at Photo Hack Day (or, more accurately, Photo Hack Weekend) in New York City this weekend. Flickr dev Paul Mison will be on hand to talk about the Flickr APIs and answer questions.
