Seller SDK

Drop-in middleware for Hono, Express and Next.js, with pricing, receipts and payouts handled.

Ship a paid endpoint in the framework you already use. The Seller SDK is the code behind Nous Gate: pricing, receipts and payouts in one middleware. Planned package name: @nouspay/gate.

Hono

import { gate } from "@nouspay/gate";

app.get("/forecast", gate({ price: "<price in ETH>", payTo: "<your wallet>" }), handler);

Express

import { gate } from "@nouspay/gate/express";

app.get("/forecast", gate({ price: "<price in ETH>", payTo: "<your wallet>" }), handler);

Next.js route handler

import { withGate } from "@nouspay/gate/next";

export const GET = withGate({ price: "<price in ETH>", payTo: "<your wallet>" }, async () => {
  return Response.json(await runForecast());
});
