https://wiki.mozilla.org/Audio_Data_API The HTML5 specification introduces the and media elements, and with them the opportunity to dramatically change the way we integrate media on the web. The current HTML5 media API provides ways to play and get limited information about audio and video, but gives no way to programatically access or create such media. We present a new Mozilla extension to this API, which allows web developers to read and write raw audio data.

unAPI.info - for all your unAPI needs

unAPI is a tiny HTTP API for the few basic operations necessary to copy discrete, identified content from any kind of web application. There are already many cool APIs and protocols for syndicating , searching , harvesting , and linking from diverse services on the web. They're great, and they're widely used, but they're all different, for different reasons. unAPI only provides the few basic operations necessary to perform simple clipboard-like copy of content objects across all sites. It can be quickly implemented, consistently used, and easily layered over other well-known APIs. unAPI was developed under the ROGUE 05 standards-making process. http://unapi.info/

Think Vitamin » Mastering the Art of APIs – Part 1

In this article I’m going to discuss some of the key issues you should try and think through before you crack out the code. As the old adage goes, failing to plan is planning to fail, and there’s nothing more embarrassing than discovering that the sexy new API you’ve just integrated into your site is ruining its stability and turning off users. With a little extra planning you can ensure a smooth ride for everyone. A Good Plan Today is Better than a Perfect Plan Tomorrow http://thinkvitamin.com/code/mastering-the-art-of-apis-part-1/
I recently became mildly obsessed with Europopped.com , a blog that highlights both really catchy & horribly tacky music videos from all over Europe, and I've started thinking up mashups to fuel my obsession. So, I looked up the API for Posterous.com , the blogging platform that powers Europopped, and discovered that its API is not quite as mashup-friendly as I hoped. They do offer an API for retrieving public feeds without authentication -- the first thing I looked for -- but the API result output is a custom XML format -- not optimal for client-side mashups. I was expecting to find an API output that was either ATOM-based, so I could pipe it through existing Feed->JS proxies like the Google AJAX Feeds API , or even better, an API output in JSON with support for callback parameters.

http://www.phpied.com/photo-canvas-tag-flip/ Today our family went to the yearly photo session with the girls. We took one shot that can be looked normally, as well as upside down, so I was wondering can you flip an image using a canvas tag. Turns out, yes, you can and it's pretty easy. Now let's load an image into the canvas. Using the new Image() constructor you can create an image object, then set its src property to point to the location of the image file. Then set an onload handler for the image which is an anonymous function to be called when the image is done loading.

oEmbed

http://oembed.com/ oEmbed is a format for allowing an embedded representation of a URL on third party sites. The simple API allows a website to display embedded content (such as photos or videos) when a user posts a link to that resource, without having to parse the resource directly. This allows the consumer to turn a URL to a Flickr photo page into structured data to allow embedding of that photo in the consumer's website. An oEmbed exchange occurs between a consumer and a provider . A consumer wishes to show an embedded representation of a third party resource on their own web site, such as a photo or an embedded video.
Introduction APIs are a great way to extend your application, build a community, excite your users and get in on the Mashup Mania spreading across the web. While there’s plenty out there wanting in on the action, there’s a lot of questions about how to actually go about creating an API for a web application. Like everything else technical on the web these days, there are tons of complicated and scary documents out there ready to intimidate the unprepared. http://particletree.com/features/how-to-add-an-api-to-your-web-service/

About the Chronicling America API - Chronicling America - The Library of Congress

Introduction Chronicling America provides access to information about historic newspapers and select digitized newspaper pages. To encourage a wide range of potential uses, we designed several different views of the data we provide, all of which are publicly visible. Each uses common Web protocols, and access is not restricted in any way. http://chroniclingamerica.loc.gov/about/api/

He made his first telescope after hearing descriptions of a new device that had begun circulating around Europe in late 1608. He refined the design into a powerful tool for astronomy.

Application Program Interfaces (APIs) are structured methods for one software application to communicate with another. APIs allow programs to interoperate and share data and services in a standard way. Here is a list of library-related APIs that library developers may find useful. If you have ideas for others that would be appropriate for this list, please contact me . Only APIs that seem to be generally useful are listed here. However, almost any library catalog will have a search API (e.g., Z39.50) and may have others as well depending on the vendor and product.

Twitter was one of the first to see what happened when traffic to the site came more from the API than the Web. It now has more than 65 million tweets per day, most coming from services that use the Twitter API. Twitter has made numerous changes to fix its API.
