Based SEO

Professional-grade SEO data at the cost it takes to fetch it. No $130/month subscriptions for data that costs fractions of a cent per request.

Open source. No markup. Powered by Base, DataForSEO and x402.

What It Does

• Keyword Overview — Volume, difficulty, CPC, competition, search intent, 12-month trends, and global breakdown for any keyword
• Keyword Finder — Discover thousands of related keywords, questions, and content ideas from a seed keyword. Filter, sort, and save what matters.
• SERP Analysis — See exactly who ranks and why for any search query

Why This Exists

SEO data is a commodity sold at SaaS margins. DataForSEO, one of the best players in this game, costs $0.002–$0.05 per request. The industry charges you $100+/month for a dashboard wrapper on top of it.

Based SEO passes through the exact data cost from DataForSEO. No accounts, no subscriptions, no minimum spend. Just the data you need, when you need it.
