Agent Discovery Audit

Audit any domain for agent-discovery readiness. Checks robots.txt, sitemap.xml, llms.txt, agents.txt, OpenAPI, agent cards, marketplace cards, x402 cards, and path consistency. One call, one score.

$0.10 USDC per call on Base (L2)
Real payment. Each call costs $0.10 USDC on Base mainnet. You need a funded wallet. No refunds — the audit runs and returns immediately.
