Not Human Search

Verified Sep 2026

Not Human Search indexes websites and MCP servers by "agentic readiness" — how easily an AI agent can interact with a site via APIs, machine-readable docs, or MCP — exposing search, per-domain reports, and a live /check crawl that returns a 7-signal readiness score. It ships a public OpenAPI spec and an llms.txt file at its API root, with anonymous access to basic queries capped at a free 10-checks-per-hour rate limit, and Stripe-billed starter/pro/scale plans for higher-volume access or commerce endpoints like score monitoring and GEO score-fix services.

Not Human Search vs TensorFeed
TensorFeed is a free, no-auth JSON API for AI-industry data: real-time model pricing, provider status/outage monitoring (polled every 2 minutes), AI news, and agent-activity feeds, plus an in-browser API playground for every free endpoint. It also publishes an x402-based Premium Agent API (USDC on Base, no accounts or keys) for ranked model-routing recommendations, and self-certifies under its own "Agent Fair-Trade" standard with Ed25519-signed receipts and code-enforced no-charge on failed calls. Live-checked in July 2026: the site, its free endpoints, and CORS support are all confirmed working.
