good APIs for mashups

This list has been superseded by Public APIs. Check there for APIs with Auth: No, HTTPS and CORS Yes.


List of data APIs that require no server-side auth or private credentials, and are thus good for small browser-only JS projects.

This gist will let you retrieve a series of tweets using the twitter v1.1 API. There's a few steps you have to do before you use this. 1. First, you need to go to http://dev.twitter.com/apps and create a new application. 2. You'll also need to download this library. https://github.com/themattharris/tmhOAuth (You only need the tmhOAuth.php file) …
<?php
require 'tmhOAuth.php'; // Get it from: https://github.com/themattharris/tmhOAuth
// Use the data from http://dev.twitter.com/apps to fill out this info
// notice the slight name difference in the last two items)
$connection = new tmhOAuth(array(
'consumer_key' => '',
'consumer_secret' => '',
'user_token' => '', //access token

Please read the comments carefully, as I start out with a non-q example, to show the order of flow. Please post comments if there's anything that isn't clear and I'll try to revise it as needed.

complete, we want to call three.
BUT, we don't want to just call our three functions in sequence, as this quick
