What is Quid?

💳

If you've ever built an API, you know the pain of monetization. You have two choices: give it away for free, or force users into monthly subscriptions with complex tier systems. What if you just want to charge $0.01 per request?

Traditional payment systems make this impossible. Credit card fees alone cost more than a penny, turning micropayments into a losing proposition. So we end up with awkward subscription tiers, free quotas, and frustrated users who just want to pay for what they use.

This is the problem Quid solves.

Stripe for Pay-Per-Use APIs

Quid makes it effortless to monetize your API with true pay-per-use pricing. Think of it as Stripe for micropayments—simple integration, powerful features, and payments that actually work at any price point.

Built on top of the x402 payment protocol, Quid handles everything:

  • One-line integration that adds payments to any API endpoint
  • Automatic payment handling so clients never see a 402 error
  • Real-time analytics showing exactly how much you're earning
  • Enterprise features including managed wallets and invoicing

How It Works

For API providers, it's as simple as adding middleware:

app.use('/api/weather', Quid({
  productId: 'weather-api',
  priceId: 'basic-tier'
}));

That's it. Your API now charges per request.

Why This Matters Now

We're entering an era where AI agents will consume billions of API calls daily. These agents need to autonomously purchase access to resources without human intervention. They need payments that work for $0.001 transactions as easily as $100 transactions.

Traditional payment infrastructure wasn't built for this world. Quid is.

What We're Building

We're not just building a payment processor. We're building the infrastructure for the programmable economy:

  • Dynamic pricing that responds to demand
  • Analytics that help you optimize revenue
  • Enterprise tools for compliance and billing
  • A marketplace where APIs can be discovered and monetized instantly

Our vision is a world where every API can be monetized effortlessly, where agents can transact freely, and where developers are paid fairly for the value they create.

Get Started

We're launching our pilot program soon. If you have an API you'd like to monetize—or if you're building agents that need to consume paid APIs—we'd love to hear from you.
