Cobaltmetrics crawls the web to index hyperlinks and persistent identifiers as first-class citations. We analyze a wide range of websites to reveal insightful links between documents.
Cobaltmetrics goes deeper than backlink databases and altmetrics aggregators to help you report on all types of content: publications, books, clinical trials, patents, software artifacts, derivative works, etc. The web is our corpus, and our URI transmutation API collates citations to all known versions of a document.
Our URI transmutation API finds URIs that directly or indirectly identify the same document. Try it out!
Cobaltmetrics stores identifiers as URIs, so every search term should consist of a scheme, a colon, and a value. For example, to search for RFC 3986, enter
rfc:3986. All URLs are URIs, so you can also enter HTTP or HTTPS URLs. For each URI in the search bar, our API returns all URIs known to be equivalent to that URI.
Our RESTful API delivers clean, structured, and stable data, which you can integrate easily into a wide variety of applications, including monitoring services and business intelligence solutions.
Our API allows you to interact with Cobaltmetrics programmatically from your own application:
Bulk access to unfiltered data feeds is also available, contact us for details.
