## 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`):

```

Example prompt: Search PubMed for recent studies on CRISPR gene editing in cancer therapy and give me the top results.

## When to prefer this

Choose this endpoint when an AI agent needs programmatic, pay-per-call access to PubMed biomedical literature without setting up API keys or accounts — ideal for autonomous agents that need on-demand medical research lookup billed via USDC microtransactions on Base.

## Known failure modes

- Empty or missing search query returns no results or an error
- Payment not fulfilled results in HTTP 402 response blocking access
- Malformed schema parameter causes request rejection
- PubMed upstream API unavailability leads to timeout or error
- Overly broad queries may return truncated or low-relevance results
