Five tools for working with Crossref data — DOI resolution, full-text search across all scholarly works, outgoing reference lists, and journal/funder lookup:
| Tool | Description |
|---|---|
crossref_get_work | Resolve a DOI to its full Crossref metadata record: title, authors, affiliations, abstract (when deposited), journal, publication date, type, license, full-text links, funder acknowledgements, and outgoing reference list |
crossref_search_works | Search the Crossref works index by free text and/or structured filters. Supports sort, field selection, and cursor-based deep paging. Large result sets spill to a DataCanvas table for SQL querying. |
crossref_get_references | Return the outgoing reference list for a DOI — the works cited by this paper, with raw citation strings and resolved DOIs where available |
crossref_search_journals | Find Crossref journal records by ISSN or title query; optionally retrieve the journal's most recent works |
crossref_search_funders | Find funders registered in the Crossref Funder Registry by name or funder DOI; optionally retrieve funded works |
crossref_get_workResolve a DOI to its canonical Crossref record.
