Hi Asoto,

Thanks for your question. You can use this call: [http://api.crossref.org/prefixes/10.5555/works](http://api.crossref.org/prefixes/10.5555/works) to get all of the works that have been published for a specific prefix. The 10.5555 is our test prefix, which you can replace with any prefix you’d like to investigate. In addition to the API results, [support](mailto:support@crossref.org) can always provide a report as a .csv file with all of the DOIs registered for a prefix as well. We’re currently working to make this .csv report available to members through the admintool, since this is a somewhat common request.

Best regards,  
Isaac
