Yahoo! has released their Developer Network. The Developer Network provides documentation and an SDK to help folks get started using the new APIs they’ve released to access Yahoo! web services. The APIs allow anyone to get results for an image search, video search, web search and more. All query results are delivered in an open XML format:

The results returned by the service are in XML which varies per service.

There has been lots of net art which uses search queries or results as the basis of the project (Cory Arcangel’s Dooogle and Thompson & Craighead’s Beacon being two recent examples). And now Yahoo! is making it super easy to use dynamic, live results in any sort of web-based art work. They provide examples in the SDK in a number of languages including Javascript, PHP, Python and Perl.

One caveat however, you must have an application ID to identify your application to the system and they limit the frequency by which you can query the system.

These rate limits are imposed independently for each service and are typically in the thousands-per-day per user range. See each service’s documentation for the individual limits.

This might be a problem for web-based software. The rate is limited by IP#, so a web site would look like one user to the system. The Image Search is limited to 5000 queries per 24 hour period. That doesn’t seem to be a great deal of queries for a popular web site. permanent link to this post
