## What it does

402registry checks whether AI agents and AI crawlers can actually see a website: a plain HTTP fetch with no JavaScript, the way GPTBot, ClaudeBot, PerplexityBot and OAI-SearchBot fetch pages. Every finding quotes what the fetch returned, with a fix. MCP tools: lookup\_site \(free registry lookup\), get\_pricing, get\_docs, get\_service\_status. Paid checks cost 0.01 each over x402 in USDC on Base, with no account and no API key. Guide: https\://402registry.com/llms.txt
