Tools

Seven tools for working with Crossref data — DOI resolution, full-text search across all scholarly works, outgoing reference lists, and journal, funder, and publisher 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.

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 by publication date

crossref_search_funders

Find funders registered in the Crossref Funder Registry by name or funder DOI; optionally retrieve funded works

crossref_get_member

Resolve a Crossref member ID to its publisher record — name, owned DOI prefixes, DOI counts, per-work-type breakdown, and per-category metadata deposit coverage

crossref_get_prefix

Resolve a DOI prefix (e.g. 10.1038) to its owning publisher — name and member ID, chaining into crossref_get_member

crossref_get_work

Resolve a DOI to its canonical Crossref record.

DOI validated against 10.NNNN/suffix regex before the upstream call

Returns title, authors with affiliations, abstract (when deposited), container/journal, publication date, work type, ISSN, license URLs, full-text link URLs, and funder acknowledgements
