Monetize any
API in one line.
Wrap a route, set a price, and start charging. Run402 handles Stripe Checkout, the 402 handshake, billing, and analytics — no payment code required.
Join the first developers shaping the future of API monetization.
Works with the tools you already ship
Built alongside early developers
Updated weekly as we build in public.
Installation
Add Run402 to any Node.js project with your package manager of choice.
$ npm install run402How it works
No billing logic. No infrastructure. No payment code. Just protect a route and charge.
Install package
Add run402 to your project. Zero config, works with any Node framework.
Protect endpoint
Wrap any route with protect() and set a price. That’s the entire integration.
Customer pays
Unpaid requests get a 402 and a hosted Stripe Checkout. No UI to build.
API unlocks
On success the request replays automatically and your endpoint responds.
Live demo
This is exactly what your users experience — drive it manually and replay as many times as you like.
- 1Send a request to a protected route
- 2Receive a 402 with a Stripe Checkout link
- 3Pay, and the original request replays
- 4Get your 200 OK — access granted
GET /premium
→ send a request to see the paywall
Developer experience
No billing logic. No webhooks to wire. No payment UI to design. Wrap a route and you’re charging.
- One import, one wrapper — no SDK glue
- Per-route pricing, subscriptions, or metered usage
- Works with Express, Fastify, Next.js & more
import { protect } from "run402" // Charge $1 for every request to /premiumapp.use( "/premium", protect({ price: "$1", metadata: { plan: "pro" } })) // Everything else stays freeapp.get("/health", (req, res) => res.send("ok"))Features
Run402 replaces weeks of payments plumbing with a single dependency.
Automatic Billing
Invoices, receipts, and revenue tracking generated for every paid request.
Stripe Checkout
Hosted, PCI-compliant payment pages spun up automatically per route.
Analytics
Real-time revenue, conversion, and endpoint performance in one dashboard.
Usage Tracking
Meter calls per key, per user, or per plan with zero extra code.
Webhooks
Subscribe to payment, refund, and usage events with signed deliveries.
Rate Limiting
Protect endpoints with per-key limits and automatic 429 handling.
Developer SDK
Fully typed client for Node, edge runtimes, and serverless functions.
One-Line Integration
Wrap a route with protect() and you’re live. Nothing else to configure.
The difference
Everything payments used to demand, collapsed into a single wrapper.
The old way
- Integrate the Stripe SDK by hand
- Write and test billing logic
- Design a payment UI

- Manage API keys and secrets
- Weeks of engineering work
With Run402
- Install one package
- Wrap your route with protect()
- Set a price
- Ship it
- Watch revenue in the dashboard
- Under 2 minutes

Meet the Founder
Manoj Paliwal
Founder & Software Engineer
Manoj is building Run402 with a simple vision: making API monetization as easy as adding a single middleware.
After working as a software engineer and building developer tools, he realized monetizing APIs is still far more complicated than it should be. Run402 exists to change that.
