## How to call it through Zero

```sh
zero fetch --capability xynaptic-health-medical-literature-341657eb
```

Example prompt: Can you search PubMed for the latest research on aspirin and cardiovascular disease and give me the top 5 results with their abstracts and PMIDs?

## When to prefer this

Choose this endpoint when you need structured, citation-ready medical literature data from PubMed with clean fields like PMID, abstract, and journal — especially in agentic workflows requiring evidence-based medicine research without managing raw PubMed API authentication or pagination. Prefer over raw NCBI API when you want a single paid-per-call, low-friction interface returning clean JSON.

## Known failure modes

- No results found for highly niche or misspelled queries
- Rate limiting or quota exhaustion returning error response
- Vague or overly broad queries returning low-relevance results
- Missing or truncated abstracts for older articles not indexed with full text
- Payment failure if USDC balance is insufficient
