Zeny Documentation

Welcome to the Zeny documentation. Zeny is the native Agentic Payment Facilitator for x402 and Machine Payments Protocol (MPP) on MegaETH.

What is Zeny?

Zeny makes it dead-simple for AI agents to pay for APIs, data, compute, or any resource using USDM on MegaETH. One API call, instant settlement, no wallet management required.

Key Concepts

  • x402 Protocol — HTTP 402-based payment standard. Agents encounter a paywall, pay via signed authorization, and get instant access.
  • MPP (Machine Payments Protocol) — Supports both one-time charges and streaming micropayment sessions.
  • Facilitator — Zeny acts as the trust-minimized intermediary that verifies and settles payments on-chain.
  • USDM— MegaETH's native stablecoin used for all settlements.
