## 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 serp402-google-immersive-product-acc59c46 -d '<json body>'
```

Example prompt: I found a product on Google Shopping and I have its page token — can you load more store listings and pricing options for it, including fetching more stores beyond the default 3-5?

## When to prefer this

Use this endpoint when you already have a Google product page_token or next_page_token from a prior search and need to expand beyond the default 3-5 store results shown in the immersive product popup. Ideal for price comparison workflows, shopping agents, or any scenario where full retailer coverage matters. Not suitable for initial product discovery — use a Google Shopping search endpoint first to obtain the initial token.

## Known failure modes

- Invalid or expired page_token returns empty or error response
- Invalid next_page_token causes failed pagination
- more_stores parameter with invalid value may be ignored or error
- Rate limiting or blocking by Google may return incomplete results
- Token from a different search session may not return valid data
