Add Lightning revenue
to your API.

Drop three lines of code. Let AI agents pay you per request in Bitcoin over the Lightning Network. No new contracts, no per-transaction fees, no replacing what you already charge.

Real Lightning · 1 sat per call · ~1 second settlement

Watch an agent buy from this API.

The button below triggers an autonomous agent on our server. It calls the paid endpoint you choose, pays the resulting Lightning invoice from a pre-funded wallet, and retries with the L402 credential — exactly what your customers' agents will do against your API once you integrate.

City:

An additional revenue stream — not a replacement.

Keep your existing pricing. Subscriptions, tiered rate limits, API keys — all unchanged. Lightning per-request runs alongside on the same endpoints.
Earn from buyers that don't have credit cards. AI agents, MCP clients, autonomous workflows — they can't use Stripe, but they can pay sats. Capture revenue from a market that didn't exist three years ago.
Settles in seconds. Final. No chargebacks, no 30-day Stripe hold, no card-network 2.9% cut. Money's in your provider account on the same call.
You keep every sat your customers pay. Lightning Enable charges a flat monthly subscription, not a percentage. One million 1-sat calls earn you 1,000,000 sats. The whole thing.

Three lines, your language.

The middleware is a tiny wrapper around our hosted producer API. Pick your stack, install one package, gate a route with an attribute or a config line.

// .NET 8 / ASP.NET Core minimal API
using L402Server.AspNetCore;

builder.Services.AddL402AspNetCore(opts =>
    opts.ApiKey = builder.Configuration["LightningEnable:ApiKey"]);
app.UseL402();

app.MapGet("/api/data", () => data)
    .WithMetadata(new L402Attribute { PriceSats = 100 });

// Node + Express
import { l402 } from "l402-express";

app.use("/api/premium", l402({
  apiKey: process.env.LIGHTNING_ENABLE_API_KEY,
  priceSats: 100,
}));

app.get("/api/premium/data", (req, res) => res.json(data));

Install: dotnet add package L402Server.AspNetCore
