Run402 lets developers monetize any API in minutes using the HTTP 402 payment flow. Instead of building billing, payment gateways, webhooks, and access control from scratch, simply protect an endpoint, set a price, and start charging. Built for AI APIs, developer tools, SaaS backends, and anyone who wants to ship paid APIs faster with a clean, developer-first experience.
Hey Product Hunt! 👋
I'm Manoj, the creator of Run402.
Run402 started from a problem I kept running into while building APIs. Building the API itself was never the difficult part monetizing it was.
Every project seemed to require the same stack: payment integration, billing logic, webhooks, access control, subscriptions, usage tracking... before you could even charge for a single endpoint.
I kept wondering:
Why can't monetizing an API be as simple as adding authentication middleware?
That question eventually became Run402.
The goal is simple: wrap an endpoint, assign a price, and let Run402 handle the payment flow so developers can focus on building products instead of billing infrastructure.
We're still in beta, and there's plenty to improve, but I'm excited to finally put it in front of the developer community.
I'd genuinely love your feedback:
What would make this useful for your APIs?
Which payment providers should we support first?
What's missing from existing API monetization tools?
Thanks for checking out Run402! Looking forward to hearing your thoughts and answering any questions. 🚀
Love how cleanly this handles the 402 flow, would be great to see built-in support for usage tiers or volume discounts per API key so devs can offer metered plans without bolting on extra logic.
Wired up one of my endpoints in like 5 minutes and the 402 flow just worked without me babysitting webhooks. Wish I'd had this a few projects ago.
A 402 flow for API monetization is such an obvious win, glad someone is finally making it dead simple. One thing that would help me adopt this: built-in usage analytics with per-endpoint breakdowns and revenue charts. Knowing which endpoints actually get hit and which ones I should reprice or sunset would be huge, especially for AI APIs where traffic patterns can be unpredictable.
Got it working on a small test endpoint in under five minutes, the HTTP 402 flow just clicks. Wish more billing tools felt this dev-first instead of dragging you through a dashboard maze.
