0xBs turns any MQTT device into a pay-per-call API. Agents discover it, invoke it, and settle USDC — in under 3 minutes, with no firmware rewrite.
Take rate on paid calls only. Free internally. Open x402 standard.



THE THESIS
Software APIs just got an agent-native payment standard (x402). Hardware — tens of billions of sensors, motors, robots, drones — is still locked behind custom firmware with no meter. That gap is the company.
Autonomous agents now browse, code, and transact without a human in the loop. They need real-world capabilities, not another chatbot.
x402 lets software charge per call in USDC. Agents already know how to pay. Hardware was left out of the standard.
MQTT devices are already deployed at planetary scale. They produce value with no way to expose it or get paid. 0xBs is the missing rail.
THE WEDGE
The insight is distribution, not a new chip. Point the MQTT broker you already run at 0xBs. Mint a key. Price a service. That's the on-ramp — minutes, not a hardware cycle.
Device → callable endpoint
Smallest settlement we can take
Servers the owner has to run
USDC chains, starting on Base
THE PRODUCT
Agents already speak x402. We didn't invent a new client. If they can pay a software API, they can pay a greenhouse sensor.
import { wrapFetchWithPayment, createSigner } from "x402-fetch";
const evm = await createSigner("base", process.env.KEY);
const pay = wrapFetchWithPayment(fetch, { evm });
const res = await pay(
"https://0x-bs-device-controller-azure.vercel.app/quote/device/DEV/service/read-temp",
{
method: "POST",
body: JSON.stringify({ params: { room: "4" } }),
},
);
console.log(await res.json());HOW IT WORKS
Point existing MQTT at 0xBs. Mint a per-device key. Nothing to flash, nothing to host.
Each action is a named service: free for your own agents, or priced per call in USDC.
An agent pays via x402. We verify onchain, the device does the work, USDC lands in the owner's wallet.
THE BUSINESS
Device owners are supply. Agents are demand. 0xBs is the rail. Connecting a device is free. We take a small cut only when a paid call settles — owners keep the rest. Internal fleets can run at $0 until they're ready to meter the outside world.
Any MQTT device in minutes. Greenhouses, cobots, drone fleets, printers. The more endpoints, the more useful 0xBs is to every agent.
Agents that already pay software APIs. Same SDKs, same x402 header, new capability: the physical world.
We only earn when value moves. No seat licenses, no hardware SKU, no lock-in. Volume on the rail is the company.
WHY IT SCALES
x402 is open. ChatGPT, Claude, MCP, and any x402 client work on day one. We win the index, not a proprietary SDK war.
Start with MQTT that already exists. Expand to robots-as-a-service, drone missions, industrial telemetry — same rail, higher ACV.
Owners only pay us when they get paid. Agents only pay for work done. The network grows because both sides make money on it.
SUPPLY
Become a paid endpoint. Keep almost everything you charge.
DEMAND
Same x402 you already use. Now it actuates the real world.
