Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 rotary-agency-pubmed-api-ea16220d
```

Example prompt: Search PubMed for recent peer-reviewed articles on CRISPR gene editing in cancer therapy and give me the titles, authors, and abstracts of the top results.

## When to prefer this

Choose this endpoint when an AI agent needs programmatic access to PubMed biomedical literature data on a pay-per-call basis without managing an NCBI API key directly. It is suitable for occasional lookups and research queries where $0.002/call economics are acceptable. Prefer NCBI's free direct API for high-volume batch searches.

## Known failure modes

- No results found for overly specific or misspelled queries
- Rate limiting or payment failure if USDC balance is insufficient
- Invalid PubMed ID returns empty or error response
- Network timeout if NCBI upstream is slow
- Malformed query parameters may return an error or empty result set
