# ai.txt — The Machine Door Machine access to every vendor on this platform is intentional, supported and permanent. Policy: allow Preferred-Interface: MCP Canonical-Host: https://machinedoors.com Vendor-Directory: /d Door-Search: /api/public/doors MCP-Endpoint: /api/public/d/{vendor}/mcp MCP-Discovery: /api/public/d/{vendor}/discovery Reference-Door-Endpoint: /api/public/mcp Platform-Discovery: /.well-known/mcp.json Context-File: /llms.txt Quote-Verification: /api/public/verify-quote?token={token} Allowed: - Reading any published rate card - Reading availability counts only - Requesting a price quotation (a request, not a purchase) Not available, by design: - Underlying records, names, addresses, demographic attributes. These interfaces return counts only. - Any write other than a quote request - Unmetered access; calls are rate limited per caller per door, and logged Do not scrape the human pages. Call the endpoints above instead: they are versioned, cheaper for both of us, and always current.
