Thirteen production playbooks from running an x402 paid API on Base: shipping the endpoint, the payment-verifier rules, the real-money buyer test, the Base RPC capability audit, CDP authentication, directory registration, consolidating Cloudflare/Solana data, an rclone Google Drive bridge, AdSense, multi-size ad slots, nginx route recovery and secure Telegram alerts. Each item carries the mechanism, the commands, the pitfalls that cost us real money and how to verify the result.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X GET 'https://xhagents.xyz/api/compute/xh-bundle' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch 'https://xhagents.xyz/api/compute/xh-bundle'
Endpoint: https://xhagents.xyz/api/compute/xh-bundle. Operated by xhagents.xyz, not by Animica. Price and availability were correct at the last probe on 2026-10-01 and are set by the operator, who may change them.
