## 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-overview-4a8f8ab5 -d '<json body>'
```

Example prompt: Search Google and get the AI Overview snippet for 'best project management software for remote teams' — I want to see what Google's AI summary says about it.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-use access to Google's AI Overview (SGE) search results without a subscription or API key setup, especially in Web3/DeFi agent workflows that support x402 micropayments. It is ideal for lightweight, one-off or low-frequency lookups where per-call billing at $0.01 USDC is more cost-effective than a monthly SERP API subscription.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 handshake fails — request rejected before forwarding
- Invalid query parameters: malformed path or query object causes upstream error
- Upstream unavailability: Google SERP API or proxy backend is down, returning 5xx
- No AI Overview available: some queries may not trigger a Google AI overview snippet, resulting in empty or null AI overview field
- Rate limiting: too many requests in a short window may be throttled

## How this service works

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

## Output

The upstream SERP response containing Google's AI Overview snippet and related search result data, passed through after successful $0.01 USDC payment via x402 protocol. Content type and body mirror the upstream Google SERP AI overview API response.
