x402 payment rails

for the agent| economy

One line of code

Two lines to monetize any endpoint.

Drop the middleware in front of any route. Set a price in USDG. Your endpoint now speaks x402.

✓Instant USDG settlement
✓Nonce-signed, replay-safe
✓Express / Hono SDKs
✓Self-host with BYO Robinhood RPC
See Docs →
server.ts
import express from "express";
import { paywall } from "@vergex402/express";

const app = express();

app.use("/api/premium", paywall({
  amount: 0.001,            // USDG
  recipient: process.env.WALLET,
  network: "robinhood-mainnet",
}));

Agent Commerce

Agents and applications can charge for API access through a complete HTTP 402 loop: challenge, stablecoin settlement, proof retry, nonce validation, and replay protection. Wallet authorization is only needed for private portal tools.

✓

Issued nonce challenge

Every 402 response carries a one-time nonce, amount, recipient, token, network, and memo for the caller to satisfy.

✓

Proof retry

The caller retries with X-Pay-Tx and X-Pay-Nonce. Verge validates settlement before your handler runs.

✓

Replay protection

Successful transaction hashes are rejected on reuse. Bring Redis/Postgres stores when you run multiple workers.

✓

Agent or app ready

Agents can automate the whole loop, while apps and scripts can use the same paid endpoint contract.

MULTICHAIN PAYMENT RAILS

One gateway.
Seven ways to settle.

Choose the network that fits your users. Robinhood Chain settles in USDG; Ethereum, Base, Arbitrum, Polygon, Solana and Sui settle in USDC.

Built-in, per-transaction cashback

Every Transaction Earns

Automatic rewards

Every settled x402 payment earns cashback. No staking, no claims — it's built into the protocol.

Decaying rate

Early adopters earn more. Cashback rate decreases as total volume grows — get in early.

USDG payouts

Rewards are paid in USDG directly to your wallet. No token swaps, no lockups.

Secure & Monetize Data

APIs, websites, datasets, MCP servers. If it returns a response, it can charge for it.

Monetize any API endpoint

Add paywall() middleware to any Express/Hono/Fastify route. Agents pay USDG per call. You earn instantly.

✓Zero vendor lock-in
✓Works with any HTTP client
✓Open source SDK
✓Self-hostable
server.ts
app.use("/api/data", paywall({
  amount: 0.005,         // $0.005 USDG per call
  recipient: WALLET,
  network: "Robinhood-mainnet",
}));

Modular by design. Composable by nature.

Six building blocks. Use what you need. Replace what you don’t.

Framework Interoperability

Express, Hono, Fastify, Koa — drop in the middleware. Same API, any framework.

Labor Exchange

Agents list compute tasks. Other agents bid and execute. Settlement is automatic via x402.

Non-Custodial

Your keys, your funds. Verge never touches your wallet. Payments go direct on-chain.

Nano-services

Price endpoints at $0.001. Robinhood fees are low. The math finally works for micropayments.

verge-router

Smart routing layer. Finds the cheapest facilitator, retries on failure, load-balances across RPCs.

Payment Rails as a Service

White-label Verge for your platform. Your brand, your fee structure, our infrastructure.

Upgrades Like API Versions

Contract upgrades are as simple as changing an API endpoint. Update your payment address, keep everything else the same.

Current Version (v1.0)
// Your existing integration
paymentMiddleware
(
  "0xverge"
, {
  path: "/api/data"
  price: "$0.01"
});
New Version (v2.0)
// Just change the address
paymentMiddleware
(
  "0xNewAddress"
, {
  path: "/api/data"
  price: "$0.01"
});

No migration scripts. No downtime. No redeployment. Just update the recipient address and your agents start earning to the new wallet.

Built for $0.001 transactions.

Stripe takes 2.9% + $0.30. That breaks at <$1 per call. We don’t.
