Why this exists

SEO data is a commodity sold at SaaS margins. DataForSEO costs fractions of a cent to a few cents per request — but the industry charges you $100+/month for a dashboard wrapper.

Based SEO is the opposite: transparent pay-per-search data. No subscriptions. No minimum spend. Just clean UI and MCP access on top of the raw data.
