How to buy a .co domain with crypto (USDC, USDT) or card

1. Search your name above to see if the .co is free.
2. Add it to your basket and choose how many years to register it for (up to 10).
3. Pay in USDC or USDT on Base, Ethereum, Arbitrum, Polygon, HyperEVM, BNB Chain or Solana, or by card (a person completes card checkout). We register it and you manage DNS from your dashboard.

Register a .co domain with an AI agent

Agents can search, quote and buy .co names without a browser. Use one-shot x402 registration (USDC on Base, no account), our MCP server at https://stabledomains.net/api/mcp with the search_domains, quote_domain and create_order tools, or a prepaid balance you top up. Agents pay with a crypto wallet or balance you fund; card checkout is completed by a human.

// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPayment } from "@x402/fetch";
// ...create an x402 client with your wallet signer (USDC on Base)
const pay = wrapFetchWithPayment(fetch, client);
const r = await pay("https://stabledomains.net/api/v1/register", {
  method: "POST", headers: { "content-type": "application/json" },
  body: JSON.stringify({ domain: "myagent.co", years: 1 }),
}); // 402 -> signs the exact live price -> 201 { order_id, status }
