  "description": "Read a public EVM wallet balance on Base or Ethereum and determine whether its Base USDC balance can cover a suggested $0.001 x402 payment. Returns a coherent provider snapshot, USDC runway, shortfall, native-gas presence, and a handoff to the full funding-readiness doctor without signing, broadcasting, or handling private keys. Balance-only readiness does not prove client, signing, spend-cap, or retry capability. GET variant for agents, crawlers, and wallets that prefer query parameters over...",
