{"type":"https://eips.ethereum.org/EIPS/eip-8004#registration-v1","name":"TollWarden","description":"Payment security firewall for x402 micropayments. Call TollWarden before settling any x402 payment to catch prompt-injection-triggered payments (attacker addresses planted in content the agent just read), replayed authorizations, overpayment, secrets leaking through payment metadata, fake/lookalike USDC contracts, and address poisoning. Returns allow/flag/block with machine-readable reasons and an Ed25519-signed, payment-bound verdict a wallet can enforce. Advisory and non-custodial — never touches keys or funds. Includes a shared counterparty reputation registry and a commitment-bound delivery-outcome ledger.","image":"https://tollwarden.com/logo.svg","services":[{"name":"web","endpoint":"https://tollwarden.com"},{"name":"x402","endpoint":"https://tollwarden.com/.well-known/x402","version":"2"},{"name":"A2A","endpoint":"https://tollwarden.com/.well-known/agent-card.json","version":"0.3.0"},{"name":"OpenAPI","endpoint":"https://tollwarden.com/openapi.json","version":"3.1.0"},{"name":"MCP","endpoint":"https://registry.modelcontextprotocol.io/v0/servers?search=com.tollwarden/tollwarden","version":"1.6.0"}],"x402Support":true,"active":true,"supportedTrust":["reputation"],"registrations":[{"agentId":59586,"agentRegistry":"eip155:8453:0x8004A169FB4a3325136EB29fA0ceB6D2e539a432"}],"agentWallet":"0x81bE42dD3fA09208DdB368749715712eC26D44d7"}
