  "description": "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. Paid endpoints are paid per request over the x402 protocol in USDC on Base ($0.01 per check), with no account and no API key: a GET without payment returns 402 with the requirements in the PAYMENT-REQUIRED header.",
