Description

Domainee is a custom domains API that lets SaaS products offer white-label domains to their users in minutes instead of months - and even sell domains directly inside their app. Connecting a domain takes a single CNAME record, with SSL certificates, renewals, and DNS verification handled automatically, while the Buy-a-Domain API turns domain registration into one API call. The first 50 domains and 100 GB of bandwidth are free forever, with no credit card required.

Key Features
- One-CNAME setup with automatic SSL: End users add a single CNAME at their registrar, and Domainee issues and renews their certificate via Let's Encrypt on the first request — no DNS validation back-and-forth.
- Buy-a-Domain API: Let users search for and purchase a domain without ever leaving your app. One API call registers the domain with your end user as the legal owner, configures DNS, and connects it to your product — at wholesale price plus a flat $1 fee, with your own markup on top.
- Stripe-shaped REST API: POST /v1/domains creates a domain, returns the CNAME, and fires a domain.verified event over HMAC-signed webhooks the moment DNS lands. Bearer keys and idempotency keys included.
- Full domain lifecycle endpoints: DNS, nameserver, and renewal management via API, so your users never have to log into a registrar.
- Hosted MCP server for AI agents: Drop one config block into Claude, Cursor, or any AI agent and get 11 ready-made tools to list, create, and verify domains in plain English — no code change.
- Real free tier: 50 custom domains and 100 GB of bandwidth every month, free forever. The free quota stays free even after you scale past it.

Benefits
- Ship custom domains the same day: What normally turns into a quarter-long infrastructure project — cert issuance, renewals, edge routing — becomes a copy-paste curl command.
- New revenue stream from domain sales: Resell domain registration inside your own product with your own markup. Your users get their domain in one click; you keep the margin and the relationship.
- No 2am cert emergencies: SSL issuance and renewal are fully managed, so your team never carries an on-call rotation for expired certificates or failed renewals.
- Your users never leave your app: From purchasing a domain to managing DNS, nameservers, and renewals, everything happens through your product instead of a registrar dashboard.
- Start free, pay only for usage: No trial expiry, no monthly minimum, no "contact sales." Every price and limit is published — from $0.20/domain/month, graduating down to $0.10 at scale.
- Future-proof for AI workflows: Every endpoint exists as both a REST surface and an MCP tool, so your product and your AI agents can manage domains the same way.
