## 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 medapi-pubmed-search-b38bf720 -d '<json body>'
```

Example prompt: Search PubMed for recent studies on metformin and cardiovascular outcomes — I need a list of relevant articles with their metadata.

## When to prefer this

Use this endpoint when you need to search PubMed's biomedical literature database programmatically — especially when an agent needs to retrieve peer-reviewed research, clinical studies, or drug-related publications. Prefer this over general web search when the user specifically wants academic or clinical evidence from PubMed.

## Known failure modes

- Empty query string returns validation error
- Overly broad or ambiguous query may return irrelevant articles
- PubMed API downtime may cause upstream failure and empty results
- Payment failure via x402 prevents access to endpoint
- Malformed query syntax may return zero results without explicit error
