arXiv Lookup

Lightweight scripts for querying the arXiv API directly via arxiv.py.

Scripts

Get Journal DOI from arXiv ID

uv run --with arxiv scripts/get_doi.py <arxiv_id>

• Returns the journal DOI if available (exit 0), or exits with error (exit 1) if not found
• This is the journal-assigned DOI, not the arXiv-assigned DOI (10.48550/arXiv.{id})
• arXiv-assigned DOI can be constructed mechanically: 10.48550/arXiv.<id> — no API call needed

Search arXiv and Get IDs

uv run --with arxiv scripts/search_id.py <query> [max_results]

• Searches the arXiv API directly (no local database)
• Returns tab-separated arxiv_id\ttitle lines
• Default: 5 results, sorted by relevance
• Query supports arXiv API field prefixes: ti: (title), au: (author), abs: (abstract), cat: (category)
• Use quotes for exact phrases: ti:"Attention Is All You Need"
• Combine with AND/OR/ANDNOT: ti:transformer AND cat:cs.CL

Integration Notes

• OpenAlex: Use get_doi.py to obtain journal DOIs for OpenAlex queries
• arxiv-doc-builder: Use search_id.py to find arXiv IDs, then pass to arxiv-doc-builder
