## 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-gateway-google-serp-search-a376806e -d '<json body>'
```

Example prompt: Search Google for 'best open-source LLM frameworks 2024' and show me the top organic results including titles, URLs, and snippets.

## When to prefer this

Choose this endpoint when your agent needs real-time Google search results without managing API keys or subscriptions — ideal for pay-per-use agent workflows on Base/USDC. Prefer over SerpAPI or similar when you want micropayment-based access with no monthly commitment and the x402 payment protocol is already integrated.

## Known failure modes

- Invalid or missing tool name parameter returns an error
- Query string too long or malformed may be rejected
- Google rate limits or anti-bot measures may cause transient failures
- Empty results returned for very niche or newly-coined queries
- Payment failure (insufficient USDC balance) blocks the request
