Keywords

Classic keyword data for a seed term, search volume, CPC, competition, and related ideas. Flat per call.

Overview

Monthly search volume, CPC, competition, and (with ideas: true) LLM-curated related keyword ideas for a seed term. This is a classic-SEO data endpoint, not a multi-model AI-search fan-out, so it is billed a flat per-call rate rather than per model.
