Google has released a "garden hose" for Google Buzz. This is a random sampling of public Google Buzz posts for developers who don't have the required resources to support the traffic that comes with the firehose.
The garden hose has a query rate under the free quote limit of Google App Engine, Google says. "As such, many more developers will be able to easily get their hands dirty on this great source of real-time data," says Google's Eric Steinlauf.
"Second, we've created an API to return the people associated with a particular activity query," he adds. "That is, you can now search for people who have recently created a public post that includes an arbitrary string or related geo-location. For example, if you wanted to see the people associated with Red Sox near Fenway Park, you could use this URL for the JSON response."
Google has also enabled users to discover content related to particular posts. Developers can access and deliver search results related to the post's topic.
More information on utilizing these features of the Google Buzz API can be found in the documentation.
