Amazon Product Advertising AWS PHP SDK helps to build applications using AWS services including unlimited cloud storage with Amazon S3, resizable clouding with Amazon EC2, and query data with Amazon SimpleDB. A getting started guide offers steps to create an account along with instructions to use this kit for the first time. Advanced features are available as well. If a developer has worked with previous versions, a migration guide can clarify the differences between the new and the previous version of the AWS SDK PHP. The guide illustrates how to modify applications in the new versions. Besides the getting started and the migration guides, an API reference describes all operations including sample requests, responses, and errors supported by AWS. A unique feature of the SDK in PHP is the AWS free tier, a training to earn free experience with AWS for 12 months.
Lately we're seeing a lot more talk about API monetization. Last week we covered TweetPhoto's efforts at encouraging developers to use the TweetPhoto API through a transactional payment model (one penny or so for each photo uploaded via the API). Last month we covered Bandsintown, which provides affiliate earnings via use of its Bandsintown API. And more recently Touchnote announced an affiliate payment model (with a whopping 30% royalty) for developers working with its image API.
