The Chirpio API lets Twitter users rate each other through an app or web site. Users can also retrieve the current ratings and score of any Twitter user that has been rated on Chirpio. The Chirpio API is free to use and there are no quotas or API keys required during the beta phase. It uses a RESTful interface and responses are formatted in XML.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
