Search the registry
Every DOI held here, by name, title, author, journal, ISSN or year. Take any list away as CSV or JSON Lines, follow it as a feed, cite any record in four forms.
Open services on every record
Feeds. feed.php is an Atom feed of the newest changes across the registry; ?prefix=10.46243 narrows it to one prefix, ?kind=registered lists new registrations only, &as=rss gives RSS 2.0.
Bulk. bulk.php hands the whole registry — or one prefix — away as JSON Lines (one full record a line, ?as=jsonl) or CSV (?as=csv); &since=2026-09-01 gives only what changed since then, for a mirror that keeps itself current.
Citations. Any record as CSL-JSON, BibTeX, RIS or an APA reference: https://registry.smartscholars.in/cite.php?doi=…, or the resolver with an Accept header (application/vnd.citationstyles.csl+json, application/x-bibtex, application/x-research-info-systems, text/x-bibliography) — the DOI system's own content negotiation.
Everything here reads the same rows the record pages show; nothing is cached apart. The API page lists the calls.
