The symbiotic relationship between APIs and end users looking to consume the data they provide, got stronger today with the release of an upgrade to ActiveMatrix BusinessWorks software from TIBCO Software. Version 6.0 of TIBCO ActiveMatrix BusinessWorks adds support for RESTful APIs and enhanced tools for managing the mashups of data drawn from multiple sources.
A mobile app using the Google Analytics API ran into a really good problem to have. It got popular. The Analytiks app had enough users that it was frequently going beyond the 50K requests per day allotted to each developer. Each users has to authenticate, but then all share a single pool of requests. By contrast, the Twitter API's per-user limit makes more sense.
