## 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-immersive-product-search-e2b1a247 -d '<json body>'
```

Example prompt: Search Google for immersive product results for 'wireless noise-cancelling headphones under $200' and give me the top listings including prices and merchant names.

## When to prefer this

Use this endpoint when you need Google immersive product/shopping SERP data and are operating in a web3/crypto-native environment where x402 micropayments are preferred over traditional API key billing. Ideal for agents that need per-call pay-as-you-go access to Google Shopping results without subscription commitments.

## Known failure modes

- Invalid or missing query parameters return a 400 Bad Request
- Upstream Google SERP service unavailable returns a 502 or 503 error
- Malformed path or query causes no results or empty response
- Rate limiting by the upstream provider may result in 429 Too Many Requests
