## 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 openverbs-scholar-search-83e155bc -d '<json body>'
```

Example prompt: Can you find me up to 15 academic papers on CRISPR gene editing applications in cancer therapy? I want the titles, authors, citation counts, and whether they're open access.

## When to prefer this

Choose this endpoint when you need structured bibliographic metadata (DOI, citation count, open-access status) for academic or peer-reviewed literature, rather than general web search. It is preferable to web search for research tasks because results are ranked by academic relevance and include scholarly metadata not available from general SERPs. Best for literature reviews, citation analysis, finding open-access papers, or locating papers by specific authors.

## Known failure modes

- Empty results if query is too specific or uses unusual terminology
- Rate limiting or payment failure for x402 calls
- Truncated author lists for papers with many co-authors
- Missing DOI or venue for very old or grey literature
- Query exceeds 700-character limit returning validation error
