## 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 x402-toolbox-biomedical-paper-search-f9fa70e2
```

Example prompt: Search for recent biomedical 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 an AI agent needs to retrieve biomedical or life-sciences literature programmatically without setting up API keys or subscriptions — the x402 micropayment handles authentication. Ideal for one-off or infrequent research queries where signing up for PubMed API or similar services is overhead. Best suited for agents doing autonomous literature discovery, evidence gathering, or research summarization tasks.

## Known failure modes

- Empty or vague schema query returns no results
- Query too broad returns low-relevance papers
- Payment not processed results in 402 response blocking access
- Malformed query string causes server-side error
- Rate limiting or worker timeout on high-latency searches

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

A JSON response containing a list of matching biomedical research papers, typically including titles, authors, abstracts, publication dates, journal names, and DOIs or other identifiers, along with a status field indicating the call succeeded and payment was accepted.
