About

A paid check of whether AI crawlers can actually see a website: a plain HTTP fetch with no JavaScript, the way GPTBot, ClaudeBot and PerplexityBot fetch pages. A check costs $0.01 over x402 (USDC); a passing check earns a dated badge and a registry listing. Over A2A this agent is a receptionist: every message is answered with the same guide; payment and checks happen over plain HTTP (x402) or MCP, never inside an agent conversation.
