How to buy a domain with stablecoins
1. Search
Type a name or an idea. We check live availability and price across .com, .net, .org, .io, .ai, .xyz, .co, .dev and .app.
2. Get a locked quote
Pick years, chain and token. Creating the order locks the price for 60 minutes and gives you an exact amount and a pay address.
3. Pay in USDC or USDT
Pay from any wallet, by QR code, by card via Coinbase Onramp, or gasless with x402. Payment is detected on-chain automatically.
4. Get your domain
Registration starts as soon as the payment confirms. Manage DNS, URL forwarding, renewals and auto-renew from the dashboard or API.

WHOIS privacy included free. Live quotes are re-checked per domain; premium names are priced individually.
For AI agents: buy a domain in two calls
REST with idempotent, price-locked orders. Agents should check availability right before buying, show the quote to the human, confirm, then pay or hand over the checkout link. See llms.txt and the OpenAPI spec.
# 1. check availability and price
curl "https://stabledomains.net/api/v1/availability?domain=example.com"
# 2. create a price-locked order (safe to retry with the same key)
curl -X POST https://stabledomains.net/api/v1/orders \
-H "Content-Type: application/json" -H "Idempotency-Key: my-uuid-1" \
-d '{"domain":"example.com","years":1,"chain":"base","token":"USDC"}'

}A domain registrar built for stablecoins and AI agents
StableDomains.net lets people and software buy domain names with crypto stablecoins. Pay in USDC or USDT on Base, Ethereum, Arbitrum, Polygon, HyperEVM, BNB Chain or Solana, and the domain is registered as soon as the payment confirms. There are no card forms and no account to create: buy as a guest, or sign in with your wallet.
It is built agent-first. Every action on this page is also available to AI agents through a documented REST API, the x402 payment protocol for pay-per-request access in USDC, and a Model Context Protocol (MCP) server that agents can connect to in one step. An agent can search for a name, get a quote, pay and receive the domain without a human in the loop.
Alongside registration you get free tools: a name generator, a domain value estimator, WHOIS lookup, a DNS and email checker, and a list of expiring domains with backlinks. See the agent and API docs to get started.
Frequently asked questions
Can I buy a domain with USDC or USDT?
Yes. StableDomains.net sells and renews domains for USDC and USDT stablecoins. Search a name, pick a chain and token, and pay from any wallet app, by QR code, or by card through Coinbase Onramp. Registration starts automatically once the payment confirms on-chain.
Which blockchains are supported?
Seven: Base, Ethereum, Arbitrum, Polygon, HyperEVM, BNB Chain (BSC) and Solana. USDC works on all of them and USDT where the token exists. Gasless x402 payments use USDC on Base.
Do I need an account?
No. You can buy as a guest and add an email for your receipt. You can also sign in with an Ethereum wallet (SIWE), and recover past orders by email at any time.
How do AI agents buy domains here?
Agents can use the REST API (OpenAPI spec at /api/openapi.json), pay per request with the x402 protocol (HTTP 402 Payment Required), or connect to our MCP server at /api/mcp to search, quote and register domains as tool calls.
What is the MCP server?
The Model Context Protocol server exposes tools such as domain search, quotes, order creation, name suggestions and expiring-domain lookups, so assistants like Claude or Cursor can buy a domain without custom code.
Is WHOIS privacy included?
Yes, WHOIS privacy is free on every domain where the registry allows it.
