How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with a total count of matching works, source metadata (provider, license, fetch timestamp, expiry), and an array of results each containing: OpenAlex ID, DOI, URL, publication year, title, author list (with IDs and names), citation count, and open-access details (is_oa flag, OA URL, OA status, and whether any repository has the full text).
Example use cases
Literature review for research paper
“Find me the top 10 most relevant academic papers on transformer neural networks — I need the titles, authors, publication years, DOIs, and citation counts so I can build my literature review.”
Checking open-access availability
“Search OpenAlex for papers on quantum computing error correction and tell me which ones are freely available to read online with links to the full text.”
Competitive landscape scan for a grant proposal
“I'm writing a grant proposal on mRNA vaccine delivery mechanisms — can you pull up to 20 recent scholarly papers on the topic from OpenAlex so I can see what's already been published?”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/research/openalex-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, citation-enriched academic paper data from the broad OpenAlex corpus (200M+ works) with open-access links, especially when cost-per-call matters ($0.003 USDC) and you need results in a machine-readable JSON format. Prefer it over general web search when scholarly provenance, DOIs, author attribution, and citation counts are required. Use it over direct OpenAlex API calls when you need a pay-per-use, infrastructure-free integration with bounded execution.
Side effects
- Empty query string (q is required and must be at least 1 character) returns a validation error
- Limit exceeding 20 causes a schema validation rejection
- OpenAlex upstream unavailability may cause a 502 or timeout
- Very niche queries may return 0 results with an empty results array
- Payment not provided or insufficient USDC balance causes a 402 response blocking the request
