## How to call it through Zero

```sh
zero fetch --capability jarvisclaw-scientific-literature-search-93a6a3d9
```

Example prompt: Search across arXiv, PubMed, and Semantic Scholar for recent papers on diffusion models for image generation — I want titles, abstracts, and citation counts.

## When to prefer this

Choose this endpoint when you need to search scientific literature across multiple databases simultaneously rather than querying arXiv, PubMed, or Semantic Scholar individually. It is especially useful when you need cross-disciplinary coverage (e.g. both biomedical and CS papers on the same topic) or when citation counts are needed to gauge paper impact. Prefer this over single-source academic search APIs when breadth and aggregation matter.

## Known failure modes

- Empty results if query is too specific or uses non-standard terminology
- Rate limiting or timeout if upstream databases (arXiv, PubMed, Semantic Scholar) are slow
- Partial results if one of the three sources is temporarily unavailable
- Irrelevant results if the query string is ambiguous or too broad
- Payment failure if USDC balance is insufficient for x402 transaction

## How this service works

Unified scientific literature search across arXiv (preprints), PubMed (biomedical), and Semantic Scholar (cross-field, with citation counts).

## Output

A list of scientific papers matching the query, aggregated from arXiv, PubMed, and Semantic Scholar. Each result typically includes the paper title, abstract, authors, publication source, publication date, and citation count where available.
