AgentAudit

What are agents buying? x402 commerce analytics built from on-chain settlement data, verified transaction by transaction.

Coverage: every wallet that a CDP Bazaar (agentic.market) listing names as its Base USDC payTo, refreshed daily, indexed from 2026-05-12. A settlement is a USDC transferWithAuthorization (EIP-3009) into such a wallet, matched to the payer's AuthorizationUsed log in the same transaction. Plain USDC transfers are excluded. Solana is not indexed. Totals are aggregates: AgentAudit does not store individual settlements beyond the latest 50 (/v1/flow).
