## 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 crawl-headlines-api-23460738 -d '<json body>'
```

Example prompt: Fetch me 10 headlines about artificial intelligence using the Crawl headlines service.

## When to prefer this

Use this endpoint when an AI agent needs to quickly surface current news headlines on a specific topic without requiring API keys or subscriptions — just a per-request USDC micropayment via x402. Ideal for lightweight news monitoring, briefings, or any agent workflow that needs fresh headline data on demand.

## Known failure modes

- Payment not provided or insufficient USDC — HTTP 402 returned
- Missing required 'topic' field — request rejected
- Topic returns no results — empty data object
- Service unavailable on Vercel deployment — 500 error
- Count parameter too large — may return partial results or error
