The Nomisma collaborative project provides stable digital representations of numismatic concepts and entities according to the principles of Linked Open Data. The representations take the form of http URIs that provide access to reusable information about those concepts as well as links to other resources. Nomisma offers several REST APIs for developers. They include Average Axis, Average Diameter, Average Weight, Closing Date, Get Label, Get RDF and Get NUDS. Response data is 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.
