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, Polygon, Avalanche, Fantom, and Gnosis. It enforces per-call USDC micropayments before forwarding requests to the RMI backend.
This is infrastructure — not a standalone product. All 210 tools live in the RMI backend. This worker handles payment verification on EVM chains.
Architecture
Client (MCP / OpenAI / LangChain / HTTP / App)
│
▼
x402 Gateway (this worker) ◄── checks USDC payment or trial balance
│
▼
RMI Backend (210 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 Coinbase CDP and PayAI facilitator (fast, federated)
Ethereum, BSC, Arbitrum, Optimism, Polygon, Avalanche, Fantom, Gnosis — self-verified via local EIP-712 cryptographic verification. The worker checks the on-chain USDC receipt via Etherscan API or equivalent. No external facilitator needed — pure cryptographic proof.
