Google Related Questions API
Google Related Questions API allows you to retrieve more results from Google's "People also ask" search block. The API is accessed through the following endpoint: /search?engine=google_related_questions. A user may query the following: https://serpapi.com/search?engine=google_related_questions utilizing a GET request. Head to the playground for a live and interactive demo.
API Parameters
Search Query
next_page_token
Required
Parameter defines the token needed to show the additional related questions that Google generates when a specifc question gets clicked. This token can be found in the Related Questions block returned in a regular Google Search API response.
Serpapi Parameters
engine
Required
Set parameter to google_related_questions to use the Google Related Questions API engine.
no_cache
Optional
Parameter will force SerpApi to fetch the Google Related Questions results even if a cached version is already present. A cache is served only if the query and all parameters are exactly the same. Cache expires after 1h. Cached searches are free, and are not counted towards your searches per month. It can be set to false (default) to allow results from the cache, or true to disallow results from the cache. no_cache and async parameters should not be used together.
async
Optional
Parameter defines the way you want to submit your search to SerpApi. It can be set to false (default) to open an HTTP connection and keep it open until you got your search results, or true to just submit your search to SerpApi and retrieve them later. In this case, you'll need to use our Searches Archive API to retrieve your results. async and no_cache parameters should not be used together.
API Results
JSON Results
JSON output includes structured data similar to related questions.
A search status is accessible through search_metadata.status. It flows this way: Processing -> Success || Error. If a search has failed, error will contain an error message. search_metadata.id is the search ID inside SerpApi.
HTML Results
This API does not have html response, just a text. search_metadata.prettify_html_file contains prettified version of result. It is displayed in playground.
