## 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-europe-pmc-api-968ac480
```

Example prompt: Search Europe PMC for recent open-access papers about CRISPR gene editing in cancer treatment and give me the titles, authors, and abstracts for the top results.

## When to prefer this

Use this endpoint when you need to search or retrieve biomedical and life sciences literature from the Europe PubMed Central database without setting up your own EuropePMC API key. It is ideal for AI agents that need on-demand access to open-access scientific papers, abstracts, and metadata in a pay-per-call model at $0.002/call, making it cost-effective for low-to-moderate query volumes.

## Known failure modes

- Empty result set if query matches no indexed articles
- Rate limiting or payment failure returning HTTP 402 if USDC payment not processed
- Malformed query strings causing parsing errors
- EuropePMC upstream outage causing timeout or 503
- Very broad queries returning truncated result sets without pagination
