crossref_get_work | Resolves a DOI to its full Crossref metadata record: title, authors, editors, affiliations, abstract (when deposited), journal or container with the volume, issue, pages, and article number that locate the work in it, ISSNs and ISBNs, publication date, type, license, full-text links, and funder ackn |
crossref_get_references | Returns the outgoing reference list for a DOI — the works cited by this paper. Each reference includes the deposited citation string and, where Crossref has resolved it, a DOI you can look up with crossref_get_work. Results are paged: referenceCount is the full deposited total, and when more remain |
crossref_search_works | Searches the Crossref works index (~155M records) by free text and/or structured filters. The generic query matches loosely across all fields; scope precisely with the field-specific parameters queryTitle, queryAuthor, and queryContainerTitle, or resolve a known citation to its DOI with queryBibliog |
crossref_search_journals | Finds Crossref journal records by ISSN or title query. Provide issn for an exact single-journal lookup, or query for title-based search returning up to rows results. Title-query results page with offset — the nextOffset enrichment carries the value for the following page, up to offset + rows = 10000 |
crossref_search_funders | Finds funders registered in the Crossref Funder Registry by name or funder DOI. Provide funder_doi for an exact single-funder lookup — the full DOI ("10.13039/100000001"), the bare registry ID ("100000001"), or either behind a doi: or https://doi.org/ prefix — or query for name-based search. Name-qu |
crossref_get_member | Resolves a Crossref member ID to its publisher/organization record: primary name, alternate imprint names, owned DOI prefixes, registered DOI counts, a per-work-type breakdown, and per-category metadata deposit coverage. Members are the organizations that register DOIs with Crossref, so this answers |
crossref_get_prefix | Resolves a DOI prefix — the registrant portion of a DOI, e.g. "10.1038" — to its owning Crossref member: the publisher name and numeric member ID. Answers "who publishes DOIs starting with 10.1038?" The Crossref prefix record carries only these three facts (no counts, coverage, or flags); the return |
