arXiv Record by ID (arXiv OAI-PMH)

arxivoaipmh/get-record

Returns the OAI-PMH metadata record of one arXiv e-print by arXiv id (for example 0704.0001 or hep-th/9901001): header (identifier, datestamp, set membership) and metadata (created and updated dates, title, authors split into surname and forenames, categories, comments, report number, journal reference, DOI, licence and abstract). An unknown id fails with an error. Metadata only (CC0), served by Eden Engine; not an official arXiv product.

omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "arxivoaipmh/get-record" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "arxivoaipmh/get-record" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "arxivoaipmh/get-record", input: { /* see input_schema */ }, dry_run: true })
