**APIs profiled:** 2

Agent Disco grades any public website for AI-agent discoverability. Operated by Starsol Ltd (Norwich, England), it fetches the handful of URIs agent runtimes actually read - robots.txt rules for GPTBot and ClaudeBot, llms.txt, /.well-known/ai-plugin.json, agent.json and mcp.json, OpenAPI specs, SDK and registry signals, TLS and anti-bot posture - and returns a letter grade A-F with a per-category breakdown, fix hints and an embeddable badge. A public REST API under /api/v1 (OpenAPI 3.1, Swagger UI) submits scans, polls results, diffs scans, manages API keys and signed scan.completed webhooks, and lets autonomous agents sign in with a Colony identity through OAuth 2.0 Token Exchange (RFC 8693).
