## 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 crawol-web-search-api-19d3e0cc -d '<json body>'
```

Example prompt: Search the web for 'latest developments in quantum computing' and return 5 results.

## When to prefer this

Use this endpoint when an AI agent needs on-demand web search without API keys or subscriptions, paying only per request in USDC via x402. Ideal for autonomous agents that need occasional search access without committing to a monthly plan.

## Known failure modes

- Payment not provided or insufficient USDC — 402 Payment Required response
- Missing required 'query' field — validation error
- Malformed request body — 400 Bad Request
- Upstream search provider unavailable — 500 or timeout
- Query returns no results — success true with empty data
