How this service works
Scholarly paper search. Send a topic or title, or one DOI; returns up to 20 published works with title, authors, year, journal or venue, type, DOI link and citation count from Crossref. Use to find and cite papers. Metadata only, no abstracts or full text. Typical response 1 to 2 s. Failed calls are not charged.
Output
A JSON object containing the original query or DOI, the total number of matching works in Crossref, the data source label, and an array of up to 20 result objects each with: DOI, URL, publication type, year, title, venue (journal or conference), list of author names, author count, and citation count.
Example use cases
Literature review for research paper
“Find me 15 academic papers on CRISPR gene editing published from 2018 onward — I need the titles, authors, journals, and DOI links so I can build my bibliography.”
Verify and cite a specific paper
“Look up the paper with DOI 10.1038/nature14539 and give me its full citation details including authors, year, journal, and how many times it's been cited.”
Discover top papers in a niche field
“Search for up to 20 published works on federated learning privacy — I want to see citation counts so I can identify the most influential papers in the field.”
Technical details
Endpoint
POSThttps://quantagentshop.com/v1/paper-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, structured bibliographic metadata for academic papers from Crossref — especially for building citations, discovering literature, or verifying publication details by DOI. Prefer it over full-text retrieval services when you only need metadata (title, authors, year, venue, citation count) and not abstracts or full paper content. It is ideal for agentic literature review workflows where speed and citation accuracy matter.
Side effects
- Invalid DOI format returns an error or empty results
- Query too short (under 3 characters) fails schema validation
- Sending both query and DOI simultaneously is not supported
- No matching papers found returns an empty results array
- Crossref API unavailability causes a failed call (not charged)
- Malformed JSON body returns a 400-level error
