## 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-related-questions-7995d08a -d '<json body>'
```

Example prompt: Can you fetch the Google-related questions (People Also Ask) for 'how to start a podcast' and keep loading more follow-up questions using the next page token from the first result?

## When to prefer this

Use this endpoint when you need structured access to Google's 'People Also Ask' (PAA) related questions without managing a Google API account, scraping infrastructure, or subscriptions. Ideal for SEO research, FAQ generation, content ideation, and question mapping workflows where you need the live PAA box results in JSON format. Use the next_page_token to recursively expand the question tree beyond the initial set. Prefer over generic SERP APIs when you specifically want question-format results rather than organic links.

## Known failure modes

- Invalid or expired next_page_token returns empty results or an error
- Google temporarily blocks scraping, resulting in empty or degraded responses
- No related questions found for an obscure or very niche query
- Rate limiting or payment failure returns a 402 status code
- Malformed JSON response if Google changes its SERP structure
