  "account": "Recall Kitchen's MCP server allows AI agents to look up product, food, vehicle, and drug recalls published by the government. Most lookups are free, but after a free usage quota, agents can pay per call using x402 in USDC on Base. To pay with x402, agents must first read the payment details from the server's /.well-known/x402 endpoint. The server returns a JSON-RPC response with an x402 Payment Required challenge when the free quota is exceeded. The payment challenge includes the network (Base mainnet - eip155:8453), asset (USDC on Base - 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), price ($0.025 per call), and pay-to address (0x8E2d8e2850Baf623A8A886DE7c80CDfB83a5cfa3). Agents using an x402-capable wallet can sign and send the payment to the specified address. After sending the payment, agents should retry the original tool call to complete the transaction.",
