Parameters from the server's own tool schema.
Despite the financial context (USDC, wallet funding, payment capability), this tool is fundamentally diagnostic and read-only. It inspects wallet state, validates quote eligibility, and checks compliance readiness without creating payments, modifying wallets, or committing financial obligations. The tool explicitly states it 'never sends a payment header' and only analyzes readiness gaps.
From the tool's definition Tool performs diagnostic checks and inspection operations: 'diagnose', 'inspect a live quote without paying', 'never asks for private keys, and never sends a payment header'.

Diagnose the buyer-side gap between seeing an x402 quote and creating a valid X-PAYMENT header: wallet address shape, Base USDC availability, max spend cap, amount/payTo/network/asset match, official x402 client readiness, typed-data signing capability, and same-request retry support. This deterministic endpoint can inspect a live quote without paying the target endpoint, never asks for private keys, and never sends a payment header to the target service. Pay up to $0.006 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised. Exact fixed-price payment and Base upto token-metered payment are both accepted when clients support them; upto settlements use actual response usage, a 0.0001 minimum, and the selected tier price as the cap. Canonical live prices: https://gpt55.558686.xyz/x402/live-prices.json. It is categorised as a Read tool in the GPT 5 5 x402 Low Cost Agent Tools MCP Server, which means it retrieves data without modifying state.
gpt55_x402_wallet_funding_readiness_doctor accepts 12 parameters: url, body, method, endpoint, max_usdc, resource, timeout_ms, amount_usdc, usdc_balance, amount_atomic, expectedAsset, expectedPayTo. The full parameter table on this page comes from the server's own tool schema.
