## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fastaf-google-scholar-search-f8b1ed6c
```

Example prompt: Search Google Scholar for papers on 'transformer neural networks for natural language processing' and give me the titles, authors, citation counts, and links for the first page of results.

## When to prefer this

Choose this endpoint when you need structured, machine-readable academic paper data from Google Scholar — especially when you need citation counts, author lists, and publication metadata in JSON format without parsing HTML. Prefer this over general web search APIs when the use case is specifically academic literature discovery, citation tracking, or research surveys. The x402 micropayment model means you only pay per successful request.

## Known failure modes

- Query returns no results for very niche or misspelled searches
- Invalid or expired cites/cluster ID returns empty or error response
- Rate limiting or credit exhaustion prevents the request from completing
- Scholar anti-scraping measures may occasionally return incomplete data
- Page number beyond available results returns empty results array

## How this service works

Academic paper and citation search API for AI agents: Google Scholar results as JSON with titles, publication details, snippets, paper links and cited-by counts when available. Supports topic queries, citation lookup and year filters for literature research. Provided by FastAF Google Scholar Search. Price: $0.005000 USDC per successful call.

## Output

A JSON object with a 'scholar_results' array where each item contains the paper title, snippet/abstract excerpt, title link URL, displayed link, and inline_links object with cited-by total and cites_id for further lookups.
