JabRef version 5.0/5.1 on Windows 10
Steps to reproduce the behavior:
I don't know how to open error console in Windows but I suspect this problem has something to do with the new inspire beta (and the old inspire is now old.inspirehep.net).
Confirmed. The import entries window doesn't show anything because no entries were returned (an empty list), The fetcher fails.
INSPIRE got a new website recently, changing INSPIRE_HOST to https://old.inspirehep.net/search would probably work but only until June (2020):
https://old.inspirehep.net/search?rg=100&of=hx&p=hep-ph/9802379
There does seem to be an unofficial (or undocumented) API (use Accept: application/x-bibtex):
https://inspirehep.net/api/literature/?q=hep-ph/9802379
As for the official API, they say to contact them to add features:
At the same time, we are working on a new public JSON API and we are currently investigating the community needs: the information and features you would like to see in the new API, the applications you have in mind, and how these could be integrated with INSPIRE. Contact us at feedback@inspirehep.net.
I contacted the INSPIRE team regarding the API Waiting for response now. In the meantime I implemented the bibtex header solution.
@larsgw FYI: Just got mail from the INSPIRE team, they now have an official API:
