The AI Overview endpoint
Google's own answer, the sources it credits, and the organic results — in one response.
Why it is a separate endpoint
Google renders the AI Overview through a different surface than the organic list, and fetching it costs a second trip upstream. Charging for that only when you ask for it is the honest arrangement, so it lives on its own path rather than inflating the price of every ordinary search.
It is also where the four rich blocks come from: sitelinks, knowledge panel, People Also Ask and related searches arrive with this endpoint, not with the plain organic page.
Request
curl --request GET \
--url 'https://serpens.p.rapidapi.com/api/v1/search_ai_overview?q=what%20is%20retrieval%20augmented%20generation&gl=us&hl=en&format=json' \
--header 'x-rapidapi-host: serpens.p.rapidapi.com' \
--header 'x-rapidapi-key: YOUR_KEY'What you get back
| Field | What it is |
|---|---|
aiOverview.text | The answer Google wrote |
aiOverview.citations[] | The sources it credits, with links |
organic[] | The ordinary ten results, in the same response |
peopleAlsoAsk, relatedSearches, knowledgeGraph, sitelinks | The blocks Google rendered alongside |
When Google renders no overview, the aiOverview key is absent, the organic results still come back, and the call is still billed — it did the work either way.
What we found running it
That third figure is the one worth sitting with: most of what Google credits in its own answer is not on the page below it. The full report.
