POST https://agentdata-api.sander-van-aard.workers.dev/web/scholar
Google Scholar search (papers with citation counts) for AI agents at $0.020 per call, from the same Serper.dev source as /web/search. Send a query, get back compact JSON: top papers with position, title, url, publication info, snippet, year and citation count. Tune with num (1-10 results), country and language (2-letter codes). Zero results is a valid, honest answer. Pay per call in USDC on Base, no account, no API key.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
