Anyone with a Lightning wallet can access your API. No bank accounts, no credit cards, no KYC required.
Simple Integration
Add payment protection to any endpoint with middleware. Works with Express, Fastify, Hono, and more.
Micropayments
Charge fractions of a cent per request. Enable pricing models that weren't possible before.
Real-time Analytics
Track revenue, usage patterns, and performance metrics. Export data for your own analysis.

How L402 works

The HTTP 402 status code was reserved for "Payment Required" since 1997. L402 finally puts it to work.

01

Client makes HTTP request

User or AI agent sends a request to your protected endpoint without any API key or pre-registration.

fetch('/api/weather?city=miami')
02

Server returns 402 Payment Required

Your server responds with a Lightning invoice and payment details according to the L402 protocol.

HTTP/1.1 402 Payment Required
WWW-Authenticate: L402
  macaroon="...",
  invoice="lnbc..."
03

Client pays the invoice

The client pays the Lightning invoice instantly, typically in under 1 second. Payment is settled immediately.

const preimage = await wallet.pay(invoice)
04

Access granted

Client retries with payment proof. Server validates and returns the requested data. The whole flow takes seconds.

Authorization: L402 <macaroon>:<preimage>
// Response: { "weather": "sunny", "temp": 75 }
