Rug Munch Intelligence — x402 Gateway (Base + EVM)

What This Is

This Cloudflare Worker is the x402 payment gateway for Rug Munch Intelligence on Base, Ethereum, BSC, Arbitrum, Optimism, and Polygon. It enforces per-call USDC micropayments before forwarding requests to the backend.

This is infrastructure — not a standalone product. All 97 tools live in the RMI backend. This worker just handles the money.

Architecture

Client (MCP / OpenAI / LangChain / HTTP / App)
  │
  ▼
x402 Gateway (this worker)  ◄── checks USDC payment or trial balance
  │
  ▼
RMI Backend (97 tools)      ◄── actual intelligence processing

• MCP clients (Claude Desktop, Cursor) connect via the rug-munch-intelligence-mcp package

• OpenAI / Anthropic / Gemini / LangChain — fetch tool schemas directly, call via HTTP

• HTTP clients (curl, bots, apps) call this gateway directly

• Web app at rugmunch.io calls through this gateway

Same backend, same tools, same payment — regardless of how you access it.

Payment Verification

Base — verified via PayAI facilitator (fast, federated)

Ethereum, BSC, Arbitrum, Optimism, Polygon — self-verified via local EIP-712 cryptographic verification. The worker checks the on-chain USDC receipt via Etherscan API. No external facilitator needed — pure cryptographic proof.
