How this service works
Single-paper lookup by DOI or title for research agents — citation count, influence, open-access status with a direct legal-OA link (Unpaywall), venue, and a TLDR. Deterministic passthrough over OpenAlex + Semantic Scholar + Unpaywall, no synthesis, cheap and fast.
Output
Returns a structured record for the requested paper including: total citation count, influence/prominence score from Semantic Scholar, open-access status (gold/green/closed), a direct legal open-access URL via Unpaywall if available, the publishing venue/journal name, and a machine-generated TLDR abstract summary.
Example use cases
Verify open access before recommending papers
“I'm building a reading list for my grad students—can you check which of these papers are freely available and grab the open-access links for the ones that are?”
Track influential citations for grant proposals
“I need to know how many times this paper has been cited and how influential it is in the field—it's going in our NSF proposal abstract.”
Quickly fact-check reference metadata
“Before I submit this manuscript, can you verify the venue, citation count, and grab the TLDR for each paper in my bibliography?”
Technical details
Endpoint
GEThttps://citepulse.theaslangroupllc.com/api/paperWhen to prefer
Use this endpoint when you need fast, deterministic metadata for a single known paper — especially when you have a DOI or precise title. Ideal for citation checks, verifying whether a paper is freely accessible, or enriching a reference list one paper at a time. Prefer this over the bibliography-batch endpoint for single lookups, and over synthesis endpoints when you want raw factual metadata rather than generated summaries.
Side effects
- DOI not found in OpenAlex or Semantic Scholar — returns 404 or empty result
- Title-based lookup is ambiguous and may return wrong paper — DOI preferred
- Paper is very recent and not yet indexed — citation data may be zero or missing
- Unpaywall has no OA record — open-access URL will be null
- Malformed DOI format causes lookup failure
- Rate limit or upstream provider outage returns 503
