Turn a target paid x402 route, buyer runtime, spend cap, expected payTo/network, request method, and receipt policy into a copy-paste buyer client adapter pack: official-style Node fetch client, Python/httpx outline, MCP tool wrapper, same-request retry checklist, environment contract, receipt capture policy, and failure-stop conditions. Built for the real quote-only drop-off where buyers can see a 402 quote but never produce X-PAYMENT. This deterministic endpoint does not call an upstream model, never asks for private keys, and never sends a payment itself. Pay $0.012 per request with x402 exact USDC on Base or Solana when advertised. Canonical live prices: https://gpt55.558686.xyz/x402/live-prices.json.
