gasless 402 payments · @quicknode/mpp + agent-proxy gateway

The Machine Payments Protocol — a multi-method 402 payment framework. Below is a debug playground that drives our agent-proxy: a Cloudflare Worker gateway that gates any upstream HTTP API behind on-chain USDC payments via permit2, EIP-3009, or direct broadcast.

Playground

Connect your wallet and send authenticated requests through the agent-proxy gateway. Choose between permit2, EIP-3009, or direct hash credentials — server pays gas in the gasless paths.
