## 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-article-lookup-dae16006 -d '<json body>'
```

Example prompt: Can you pull the full details for PubMed article PMID 34567890 — I need the title, authors, journal, and abstract?

## When to prefer this

Use this endpoint when you have a specific PubMed ID (PMID) and need structured article metadata — title, abstract, authors, journal, and date — rather than searching for articles by keyword. It is ideal for citation verification, literature review enrichment, or resolving a PMID reference into human-readable details.

## Known failure modes

- Invalid or non-existent PMID returns success: false with no data
- Network timeout if PubMed/NCBI upstream is slow
- Missing pmid field in request body causes validation error
- PMID for a retracted article may still return metadata without retraction notice
- Payment failure (insufficient USDC) returns 402 before the request is processed
