How this service works
Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).
Output
Returns a JSON object containing a list of matching scholarly works or entities from OpenAlex, including metadata such as titles, authors, publication dates, institutions, citation counts, open access status, and related concepts. The number of results is controlled by the per_page parameter.
Example use cases
Literature review for a research paper
“Find me scholarly articles on the mental health effects of social media use — search OpenAlex and give me the top 10 results with titles, authors, and publication years.”
Tracking citation impact of a scientific topic
“Search OpenAlex for papers on mRNA vaccine technology and show me how many results there are and who the most cited authors are.”
Competitive academic landscape analysis
“I'm writing a grant proposal on quantum computing applications in drug discovery — can you pull recent research from OpenAlex so I can see what's already been published in this space?”

Endpoint
GEThttps://worlddata402.worlddata402.workers.dev/v1/research/openalex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need open-access academic and scholarly data — papers, authors, institutions, and citations — without requiring a subscription to proprietary databases like Scopus or Web of Science. It is ideal for AI agents doing literature reviews, research summarization, or academic landscape analysis that need to pay per call without a subscription commitment.
Side effects
- Missing required query parameter 'q' returns a validation error
- Very broad or ambiguous queries may return irrelevant results
- Query terms with no matches return an empty results array
- Payment failure (insufficient USDC balance) results in a 402 response before data is returned
- Rate limiting or upstream OpenAlex API unavailability may cause timeouts or 5xx errors
