I have a working DOI for an article published in March 2023, that redirects as expected to the article on arXiv:
But trying to access the same DOI via Crossref API (REST or XML) fails with ‘no resource found’ . I have successfully retrieved other DOIs using the same url syntax I’m using for this one, so I believe there is something wrong with the DOI itself in the crossref DB.
I used the xml to try to check for an aliased doi, as per another post on this forum, but since the xml doesn’t return results, I can’t tell if it is aliased.
Thanks for your help!
