## How to call it through Zero

```sh
zero fetch --capability most-cited-papers-daf7132f
```

Example prompt: Can you find the most cited papers on transformer neural networks? I need the titles, authors, DOIs, and citation counts so I can identify the foundational work for a literature review.

## When to prefer this

Choose this endpoint when you need to identify foundational or highly influential academic papers on a topic for literature reviews, grant proposals, or research orientation. It is especially useful when citation count is the primary ranking criterion and when you need structured metadata (DOI, abstract, venue) alongside results. Prefer this over general web search for academic work, and over arXiv-only sources when you need cross-disciplinary coverage across all fields indexed by Crossref.

## Known failure modes

- Topic query too broad or ambiguous — may return papers from unintended sub-fields
- Crossref citation counts may lag behind other databases (e.g. Google Scholar) or miss self-citations
- No results found for very niche or emerging topics with few indexed papers
- Query string not provided or malformed — returns error
- Rate limits or payment failure may block the request
