Google Feed API making any feed content available for developers to embed on their sites; Google launched “a new version of the Feed API, which includes push updates. With this, you’ll be able to make the latest feed data available to your visitors – when it’s available – without polling or requiring a page refresh. The best part is that this’ll work with any PubSubHubbub enabled feed. The video embedded below shows, new version works much like the older Feed API. But instead of loading existing feed data, you actually subscribe to feed, and your callback is executed any time new feed data comes in.
We’re initially making it available on a sign-up basis. Please fill out this form, telling us a little about how you’d like to use this API, and we’ll try to give you access as soon as possible,” writes Google.
