Payment infrastructure for AI agents

x402 & MPP payment facilitator on MegaETH. Agents pay for APIs, data, and compute with USDM — one call, instant settlement.

typescript

import { ZenyClient } from "@zeny/sdk";

const zeny = new ZenyClient({ apiKey: ZENY_KEY });

const tx = await zeny.settle({
  payTo: "0xSeller...",
  amount: "0.01",
  network: "megaeth",
});

Why Zeny

The payment layer that agents actually need.

No wallets, no keys

Agents don't manage private keys. Zeny handles verification and on-chain settlement through cryptographic authorization.

Sub-100ms finality

MegaETH settles in 10ms blocks. Payments confirm before your agent's next API call.

x402 + MPP unified

One integration covers both payment protocols. No need to choose — your agents work across the entire machine payment ecosystem.

How it works

Three steps. One API call. On-chain settlement.

Agent requests a resource

The server responds with HTTP 402 and USDM payment requirements.

Payment-Required header

Zeny verifies & settles

Signature verification, balance check, and on-chain USDM transfer — all in one call.

<100ms on MegaETH

Access granted instantly

The agent receives the resource. Every settlement is verifiable on-chain.

Tx hash returned

Built for production

Everything agents need to transact autonomously.

x402 Native

Full HTTP 402 implementation — verify, settle, and discover endpoints.

MPP Support

Charge and session intents for streaming micropayments.

USDM Settlement

All payments settle in MegaETH's native stablecoin. No volatile assets.

10ms Blocks

MegaETH's real-time finality means payments confirm instantly.

Non-custodial

Zeny never holds funds. Cryptographic authorization only.

On-chain Proof

Every settlement produces a verifiable transaction on MegaETH.

Use cases

From one-off API payments to continuous micropayment streams.

Agent → API

x402

AI agents pay for premium API access on demand. No subscriptions — pay per call in USDM.

Agent → Agent

x402

Agents pay each other for specialized services — research, computation, analysis. Fully autonomous.

Streaming micropayments

MPP

Pay-as-you-go for LLM tokens, data feeds, or continuous compute via MPP session channels.

Trust model

Non-custodial by design. Zeny verifies cryptographic signatures and settles directly on MegaETH. Funds flow from payer to payee — the facilitator cannot redirect payments.
