Who is this agent wallet — the identity half of agent trust — x402 proves payment; this answers whether the wallet should be recognised. Resolves a wallet's onchain identity — Coinbase verification (a KYC'd attestation), Basename, and an ERC-8004 registry entry when configured — and corroborates with its payment track record. One verdict: recognised / named / anonymous / unknown. The identity leg alongside x402-seller-check (endpoint) and agent-reputation (behaviour). Identity is not intent; a degraded read is 'unknown'. Not financial advice. Required input: agent. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool.
