## 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 quantaflow-serp-google-ai-mode-search-b5e06e3d -d '<json body>'
```

Example prompt: Search Google AI Mode for 'best practices for LLM prompt engineering in 2025' and bring back the AI-synthesized overview and top results.

## When to prefer this

Choose this endpoint when you need programmatic access to Google AI Mode search results — specifically the AI-synthesized overviews and SERP data that Google surfaces in its AI-powered search experience — and you are operating in a web3/x402-payment context where microtransactions per call ($0.01 USDC) are acceptable. Prefer this over standard Google Search APIs when you specifically need AI Mode results rather than traditional organic listings.

## Known failure modes

- Payment failure (x402): USDC payment not processed, request blocked before reaching upstream
- Invalid or missing query parameters: upstream returns error if required search parameters are absent
- Google API rate limiting: upstream may return 429 if the underlying Google Search quota is exceeded
- Malformed path or query object: incorrect routing to the upstream service returns 4xx
- Service unavailability: Vercel deployment or upstream Google SERP service may be temporarily down

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The upstream response passes through directly after payment — typically a JSON payload containing Google AI Mode SERP results, including the AI-generated overview/synthesis, organic search result listings, titles, URLs, snippets, and potentially knowledge panel data, depending on the query.
