337 SEO & GEO endpoints · pay per request · no account, no API key

The SEO & GEO API your AI agents can pay for themselves.

Every DataForSEO endpoint - keywords, backlinks, site audits, SERPs, and AI-search visibility - behind one API. A human uses the dashboard; an agent hits the same endpoints and pays per call in USDC over x402. No subscription. No markup. No key to leak.
