How this service works
Academic literature from Crossref, the DOI registry itself. Search by topic, author or exact DOI and get normalised records with citation counts, journal, publisher, authors with affiliations, and an open-access flag, plus a cohort view: median citations, most-cited work and the year range. Filter by minimum citations, publication year or open access only.
Output
Returns a list of normalized academic paper records including title, DOI, citation count, journal, publisher, authors with affiliations, and open-access flag; plus cohort-level statistics including median citations, the most-cited work in the result set, and the year range covered.
Example use cases
Literature review for research paper
“Search for the top 25 most-cited academic papers on mRNA vaccine technology published since 2015, and give me citation counts, journal names, and whether each is open access.”
Exact paper lookup by DOI
“Look up the academic paper with DOI 10.1126/science.1225829 and give me all the details — authors with affiliations, citation count, publisher, and open-access status.”
Author publication profile
“Find papers authored by Yoshua Bengio on deep learning, show me citation counts and journals, and tell me what the median citation count is across his works in the results.”

Endpoint
GEThttps://x402-filings.datalayer.workers.dev/v1/research/papersWhen to prefer
Choose this endpoint when you need structured, normalized academic paper metadata sourced directly from Crossref — the authoritative DOI registry — especially when citation counts, author affiliations, open-access status, and cohort-level citation statistics are needed in a single call. Prefer this over general web search for scholarly literature when you need machine-readable bibliometric data rather than raw HTML or PDFs.
Side effects
- Invalid or non-existent DOI returns empty results or 404-style error
- Overly broad query with no filters may return low-relevance results up to the limit
- Very high minCitations filter may return zero results if no papers meet threshold
- Author name ambiguity may return papers by multiple different authors with the same name
- fromYear filter with very recent year may return sparse results if indexing is delayed
