Keyword Research API
The freshest keyword data is on the result page: the questions Google clusters around a topic, the searches it suggests next, and which SERP features a query triggers. All of it comes back in the same response as the organic results.
Who it's for
SEO platforms building keyword databases, content teams expanding topic clusters, and tools scoring keywords by SERP features.
What you get
- People Also Ask questions per keyword — a ready-made cluster of subtopics
- Related searches for expansion at the tail
- Which SERP features fire per keyword, for prioritisation
- AI Overview presence as a signal for which queries are shifting to AI answers
