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 agentai-pubmed-ncbi-biomedical-research-api-2ded3121
```

Example prompt: Search PubMed for the latest research papers 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 you need to search or retrieve biomedical and clinical research literature from PubMed/NCBI, especially when you require access to abstracts and citation metadata across 34M+ papers. Prefer over general web search when you specifically need peer-reviewed medical or life-sciences publications indexed by NCBI.

## Known failure modes

- No results found for highly specific or obscure query terms
- Payment failure if x402 micropayment of $0.002 USDC is not processed
- Rate limiting if too many requests are made in rapid succession
- Malformed query returns empty or irrelevant results
- NCBI upstream outage causes lookup failure
