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

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
