💡Try in-browser, integrate via x402 SDK, or let AI agents call APIs autonomously using the OpenClaw skill.

Native SDKs

Integrate in minutes with our lightweight client libraries.

npm install NoFxAiOS/claw402-js
import { Claw402 } from "claw402"

const client = new Claw402({
  privateKey: process.env.WALLET_KEY,
})

const btc = await client.coinank.fund.realtime({
  productType: "SWAP",
})

🔒 Private keys are never transmitted. Authorizations are signed locally.
