Keyword Research API

br0ski777/keyword-research-x402

This server taps Google Suggest to pull keyword ideas and scores them for search intent, helping you find long-tail variations without leaving your Claude conversation. The x402 designation suggests it's part of a larger toolkit, though the repository itself is light on implementation details. You'd reach for this when doing SEO research or content planning and want to skip opening a dozen keyword tools. It runs as a remote service over SSE at keyword-research.api.klymax402.com, so there's no local setup. The intent scoring is the interesting bit here, since raw Google Suggest data doesn't tell you whether people are looking to buy, learn, or just browse.
