AgentLair

AI

AgentLair is identity, trust, and infrastructure for AI agents. Anonymous x402-payable endpoints: pay 0.001 USDC for an A2A AgentCard trust audit, 0.005 USDC to resolve an agent handle to its DID + JWKS, 0.01 USDC to query a trust score, or 0.0001 USDC to submit behavioral events. No API key required — payment is authentication.

Pay from $0.0001 to $0.01 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Attributed pro-quota: this payout address is shared, so volume and buyers are the operator-level figure divided by the services sharing it. A declared convention, not an individually observed measure, and still a conservative undercount.

Top buyer share is a concentration signal, not part of the ranking score.

All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/agentlair/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).
