GPU402

01 —— How it works / Step 1 · Quote

Ask for a GPU. Get a price.

The agent calls the gateway. It answers HTTP 402 with the price of a 15-minute block, taken from Lium’s live market.

Every GPU here is a real machine, on a Subnet 51 miner.

Drag your pointer across it. The fans spin up while a pod is live.

02 —— Playground

Don’t take our word. Send it.

Every button here hits the live gateway. Price a GPU, read its 402, then rent one with your own wallet.

Ask the gateway what this GPU costs right now. Nothing is paid.

The real response appears here.

rent.ts

import { Gpu402Gateway } from "@gpu402/tools";

const gw = new Gpu402Gateway({
  url: "https://calibration-dee-various-cooking.trycloudflare.com",
  wallet: process.env.AGENT_PRIVATE_KEY, // USDC, no gas
  payWith: "usdc", // or "tao"
});

const quote = await gw.quote({ gpu: "RTX 4090", blocks: 1 });
const { data: pod, payment } = await gw.rent({
  gpu: "RTX 4090", blocks: 1,
  sshPublicKey, // your OpenSSH public key
});
const ready = await gw.waitReady(pod.podId);
console.log(ready.ssh.command, payment.txHash);

Updates as you pick a GPU and time on the left.

04 —— Packages

Two packages. One line to a GPU.

Live from the npm registry. Use the SDK with your Lium key, or give the tools to an agent and let it pay.

The SDK

npm

Rent the cheapest Lium GPU, run a job over SSH, stop it. Inside a budget.
