This week in APIs- June 14-18 »

Here's the best of what happened this week in APIs!

Opera 10.6 Beta- The Opera 10.6 beta was announced- the new version implements W3C's Geolocation API. Is this a sign that the browser is moving away from plug-ins and into APIs for more functionality? Either way, we expect a lot more browser innovation with APIs.

Retail APIs- Over at InfoWorld, Neil McAllister wrote up a big new opportunity for retail: open APIs. Neil illustrates how companies like Amazon, Zappos, Tesco and Sears are opening up their APIs to reach customers in the new multi-device, multi-channel world. Big theme- the new emerging role of developers who can build APIs right. 

Twitter OAuth Switchover- The Twitter API team announced that they are moving back the date of the "OAuth switchover"- when they will no longer support basic auth. On August 16th Twitter will be ramping down rate limits on basic auth by about 10 calls/hour/day, ending on August 31 when basic auth won't be accepted.

New APIs- Every week there are new APIs! Here's what we're excited about right now:

• Plancast- a service for sharing future plans with your social network- announced an open read/write API. The world of social planning is heating up- and APIs are a critical part of the movement. 
• The State of California introduced 10 new APIs on their http://data.ca.gov/ site; including ones to get hospital locations, draw household and county population data, and find EDD office locations. Great signs that California is not only getting Gov 2.0, but also geolocation. We also like the clean way they lay out data sets- best practice for government agencies. 
• Infochimps- a data marketplace- just opened up an API which offers access to its Twitter and U.S. Census datasets. Lots of great information to build apps with and check out their business model- pricing to the API is tiered based on number of API calls per month- what do you think?
