AgentRank is the settlement-grounded trust check for AI agents. Before your agent pays, hires, or extends credit to another agent or x402 service, call check_agent_trust to see if it is real and settlement-backed: a 0-1000 reputation score computed from real on-chain USDC settlement (sybil-resistant, continuously stress-tested against collusion). Also: gate_caller (gate your own service by a caller's rank), classify_x402_address (real service vs rail vs treasury vs dust), and state_of_x402 (the de-noised census of the whole x402 economy). 78% of x402 counterparties are unverifiable ghosts; AgentRank tells you which are real.
