The default bibtex exports from Semantic Scholar(S2) libraries do not include DOIs, which is problematic for some. This simple CLI app scratches that itch for you. It creates a new bibtex file with the missing DOIs. You may find it useful to ask Zotero SciHub plugin to fetch PDFs or find citation counts (with other plugins).

1. Install the deps

   pip install -r requirements.txt
   

2. Run in CLI

   python doi_lookup.py my_semantic_scholar_exported.bib
   

3. Check the results.

We basically use the official S2 API to fetch full information with S2-assigned CorpusId number. The basic lookup quota is pretty generous and should suffice most library sizes.
