## 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 lion-x402-web-search-json-3e6f3d71
```

Example prompt: Search the web for the latest news on quantum computing breakthroughs and give me the results as structured JSON.

## When to prefer this

Choose this endpoint when your agent needs web search results in a clean JSON format without managing API keys, and you are already operating within an x402 micropayment-enabled pipeline on Base. It is ideal for autonomous agents that need keyless, pay-per-use access to live web data, especially when integrating with other x402-compatible services. Prefer it over traditional search APIs when low-friction crypto micropayments ($0.01 USDC per call) are preferable to subscription-based or key-gated alternatives.

## Known failure modes

- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Invalid or missing search query parameter — returns 400 Bad Request
- x402 payment channel not properly initialized — payment handshake fails
- Search backend unavailable — returns 503 or empty results
- Query returns no results — resolved may be false or result set empty

## How this service works

Keyless attested data for autonomous agents. USDC on Base via x402. Official @x402/* middleware.

## Output

A JSON object containing web search results, including an asset_id field ('LION') and a resolved boolean indicating success, plus the underlying search result data for the query submitted.
