How this service works
Search academic papers across Semantic Scholar (default), arXiv, PubMed, and OpenAlex. Input: query plus optional source, year range, field of study, and limit. Output: papers normalized to a single shape with titles, authors, abstracts, citation counts, and links.
Output
A JSON object containing the original query, a result count, and an array of up to 50 papers each with title, author list, abstract, publication year, citation count, journal name, publication date, a Semantic Scholar URL, and an open-access PDF URL if available.
Example use cases
Example prompt
“Find me up to 15 recent academic papers on transformer architectures in Computer Science published between 2021 and 2024, including their abstracts and citation counts.”
Technical details
Endpoint
POSThttps://academic.withzero.ai/run?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured metadata from peer-reviewed academic literature, especially when you want citation counts, abstracts, and year/field filters in a single call. Prefer this over general web search when the user specifically wants scholarly sources indexed by Semantic Scholar. It requires no API key and costs only $0.001 per call, making it ideal for lightweight or high-frequency research queries.
Side effects
- Empty results if query matches no indexed papers — resultCount will be 0
- Null abstract if Semantic Scholar has no abstract stored for that paper
- Null pdfUrl if no open-access PDF is available
- Null year or publicationDate for older or incomplete records
- Rate limiting or upstream Semantic Scholar API errors returning a non-200 response
- Payment failure if insufficient USDC balance for the $0.001 per-call fee
