## 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 serp-x402-vercel-app-7d908fc7
```

Example prompt: Search Google for 'best open source LLM frameworks 2024' and give me the top 10 organic results — titles, URLs, and descriptions — defaulting to United States results.

## When to prefer this

Use this endpoint when you need Google organic search results programmatically for any query, especially when relevance ranking and broad web coverage matter. Prefer this over Bing alternatives when Google's ranking signals are required, and over news/shopping endpoints when you want general web results rather than articles or product listings.

## Known failure modes

- Missing required 'q' query parameter returns a validation error
- 'num' value exceeding 100 may be clamped or return an error
- Invalid location string may fall back to US defaults or return no results
- Payment failure (insufficient USDC balance) returns HTTP 402
- Rate limiting or Google-side blocks may return partial or empty results
