How this service works
Google Related Questions: You will be able to retrieve more results using the API Structured JSON, USD 0.05 per call in USDC — no API key, no account, no subscription, no minimum. Not affiliated with, endorsed by or an official channel of any of the services the results come from. All trademarks and copyright remain the property of their respective owners.
Output
Returns a structured JSON array of related questions from Google's 'People Also Ask' feature, including question text, answer snippets, source links, and a next_page_token that can be used to load additional dynamically generated questions triggered by expanding specific questions.
Example use cases
SEO content gap research
“I'm writing a blog post about 'intermittent fasting for beginners' — can you pull all the Google related questions people are asking about that topic, including the follow-up questions you get by expanding each one?”
FAQ section generation for a product page
“I need to build a FAQ section for our 'project management software' landing page — can you get me the People Also Ask questions Google shows for that term so I know what real users are wondering about?”
Competitor question landscape analysis
“Can you grab all the related questions Google surfaces for 'best CRM for small business' and then paginate through to get the deeper follow-up questions too? I want to map out everything prospects are asking.”
Technical details
Endpoint
POSThttps://serp402.com/api/v1/google-related-questions?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
