InstaDomain


Domain registration for AI agents. Check availability, buy domains, and configure DNS without leaving your terminal.

InstaDomain is an MCP server that lets AI coding assistants (Claude Code, Cursor, Windsurf) register domains on your behalf. Pay with Stripe Checkout, Stripe MPP (Machine Payments Protocol via Shared Payment Tokens), or x402 (USDC on Base). Domains are registered in your name with Cloudflare DNS auto-configured.

Why?

You're building a project in Claude Code. You need a domain. Today you alt-tab to Namecheap, search, add to cart, fill out forms, configure DNS. That's 10 minutes of context-switching.

With InstaDomain, your AI agent checks availability, shows you the price, and buys it in one conversation. DNS is ready before you finish your next prompt.

Features

• Check domains - single domain with pricing, bulk check up to 50, or AI-generated suggestions
• Buy domains - Stripe checkout (card), Stripe MPP (autonomous fiat via Shared Payment Tokens), or x402 (USDC on Base, no signup required)
• Automatic DNS - Cloudflare zone created with scoped API token returned to you
• Your domain, your name - registered as your property, not ours
• Transfer out anytime - EPP auth codes and domain unlock built in
• Auto-renew - enabled by default, renew via Stripe
• WHOIS privacy - enabled by default

        brewbox.io - $52.49 (available)
        dailygrind.co - $35.99 (available)

You: Buy coffeecrate.com

Claude: I'll need your registration details...
        [collects name, email, address]

        Stripe checkout created. Complete payment here:
        https://checkout.stripe.com/...

        Domain registered! DNS zone created on Cloudflare.
        Your scoped API token: cf_...

| TLD | Price | |-----|-------| | .com | ~$18 | | .io | ~$52 | | .dev | ~$21 | | .co | ~$36 | | .ai | ~$99 |

Prices include 1-year registration and WHOIS privacy.

x402 Crypto Payments

InstaDomain accepts x402 payments in USDC on Base. No signup, no API keys. Your AI agent pays directly from a wallet.

This enables fully autonomous agents to register domains without human payment intervention.

MPP (Machine Payments Protocol)

InstaDomain implements Stripe's Machine Payments Protocol so agents can pay with fiat (cards, Link) or stablecoins via Shared Payment Tokens — no browser checkout, no human in the loop.

The flow:

1. POST /buy/mpp to create an order — returns a pay_url.
2. GET /pay/mpp/{order_id} with an MPP-enabled HTTP client. The first response is HTTP 402 with a WWW-Authenticate challenge. The client mints a Shared Payment Token via the advertised Stripe Business Network profile and retries with an Authorization header. The server charges the SPT through Stripe and returns the receipt in Authentication-Info.

REST API

InstaDomain also exposes a REST API for non-MCP integrations:

• GET /check/{domain} - check availability + price
• POST /check - bulk check (up to 50 domains)
• GET /suggest?keyword=coffee - AI-generated domain suggestions
• POST /buy - initiate Stripe purchase
• POST /buy/mpp - initiate MPP (Shared Payment Token) purchase
• GET /pay/mpp/{order_id} - 402-paywalled endpoint (MPP)
• GET /status/{order_id} - check order status
• POST /renew/{order_id} - renew a domain

FAQ

Do I actually own the domain? Yes. You are the legal registrant on record with OpenSRS (Tucows). InstaDomain is listed as admin/tech contact for service management, but you hold all ICANN rights. WHOIS privacy is on by default so your details stay private.

How does DNS get set up? After payment clears, InstaDomain automatically creates a Cloudflare DNS zone for your domain and returns a scoped API token. Your domain points at Cloudflare's nameservers and is ready to use. No manual configuration required on your end.

Can I transfer my domain to another registrar? Yes, anytime. Use get_transfer_code to get your EPP auth code and unlock_domain to remove the registrar lock, then initiate the transfer at your destination registrar. Note: ICANN requires a 60-day lock after initial registration before transfers are allowed.

What if I want to manage DNS somewhere other than Cloudflare? Update the nameservers at InstaDomain's registrar panel or contact support. The Cloudflare zone is set up for convenience, not as a lock-in.

Legal

Domains are registered through OpenSRS (Tucows). You are the legal registrant. InstaDomain is listed as admin/tech contact for service management only. Full ICANN rights apply, including the right to transfer your domain at any time.
