Pass any DOI as doi=10.xxxx/yyyy (limit 1-200 on the lists; timespan is an ISO-8601 duration like P0Y0M11D). Data from OpenCitations (CC0). A citation-network / bibliometrics tool — incoming citations, self-citation detection and citation timespan, distinct from scholarly-metadata lookups (Crossref, OpenAlex). Ideal for bibliometrics, research-impact, science-mapping and reference-management tools.",
