The Cobaltmetrics API provides access to citations, statistics, data sources, URI transmutation, and quotas found in documents online. The URI transmutation service finds URIs that directly or indirectly identify the same document. The API, in REST architecture, returns HTTP headers and authenticates with an API Key. Cobaltmetrics crawls the web to index hyperlinks and persistent identifiers as first-class citations.
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.
