How this service works
Scholarly search API - academic papers and research articles for a query, powered by OpenAlex. Returns ranked works with title, authors, year, venue, DOI, citation count and open-access status. A google-scholar-style research / scholarly articles search for agents. Data source: OpenAlex (CC0).
Output
A ranked list of up to 50 academic works, each containing: paper title, list of authors, publication year, venue/journal name, DOI, citation count, and open-access availability flag. Data is sourced from the OpenAlex open dataset (CC0 license).
Example use cases
Literature review for thesis research
“Search for the top 20 scholarly papers on transformer architectures in natural language processing — I need titles, authors, publication years, venues, and citation counts to build my literature review.”
Verifying author's publication record
“Find academic papers by Geoffrey Hinton on deep learning and neural networks — give me up to 10 results with titles, venues, years, and DOIs.”
Discovering open-access climate studies
“Look up recent research articles on permafrost thaw and methane emissions — I only need 5 results but I want to know which ones are open access so I can read the full text.”
Technical details
Endpoint
POSThttps://search.openverbs.com/v1/scholar?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured bibliographic metadata (DOI, citation count, open-access status) for academic or peer-reviewed literature, rather than general web search. It is preferable to web search for research tasks because results are ranked by academic relevance and include scholarly metadata not available from general SERPs. Best for literature reviews, citation analysis, finding open-access papers, or locating papers by specific authors.
Side effects
- Empty results if query is too specific or uses unusual terminology
- Rate limiting or payment failure for x402 calls
- Truncated author lists for papers with many co-authors
- Missing DOI or venue for very old or grey literature
- Query exceeds 700-character limit returning validation error
