## How to call it through Zero

```sh
zero fetch --capability agent-hub-academic-paper-search-95762479
```

Example prompt: Search for the top 10 most cited academic papers on transformer neural networks published from 2017 onward and give me each paper's title, authors, abstract, and a PDF link if available.

## When to prefer this

Choose this endpoint when you need broad academic literature search across 250M+ works with bibliometric metadata (citations, DOI, open-access PDF). Prefer it over general web search when you specifically need structured scholarly metadata. It is especially strong for open-access discovery and citation-ranked retrieval without requiring an API key from Semantic Scholar, PubMed, or similar services.

## Known failure modes

- Missing required query parameter 'q' returns a validation error
- Very niche or misspelled queries may return zero results
- Some papers may lack open-access PDF links or abstracts in OpenAlex
- Limit values outside 1-25 range may be rejected or clamped
- Payment failure (x402) if USDC balance is insufficient
