For Resellers & Platforms
Domain Reseller / Programmatic API
Provision and manage domains for your own customers at volume — bulk search, DNS, and portfolio data, across thousands of TLDs, all through one API and one managed registrar. Built for resellers, developers, and other technical or AI-powered users. Programmatic registration and renewal are coming soon.
If domains are part of what you sell or build — a hosting platform, a website builder, a brand-services agency — the registrar behind you matters. You need an API that handles volume cleanly, reaches the extensions your customers ask for, and backs you with a team of domain experts when a registry requirement gets complicated.
What you can build on it
- Customer-facing domain search — embed single and bulk availability checks (up to 50 names per request) directly in your product.
- DNS management — read and write DNS records and manage nameservers on behalf of your customers.
- Portfolio & account data — pull domain lists, renewal dates, and pricing to power your own dashboards.
- Automated provisioning · COMING SOON — register and renew domains for customers programmatically, with contact handling built in.
Breadth and pricing your customers will ask for
The catalog reaches thousands of TLDs, including ccTLDs and specialty extensions most registrars don't carry — so you're not turning customers away for lack of coverage. Pricing and renewal data come back with results, and the TLD endpoints surface registration requirements per extension before you commit a customer's order.

Building agent-driven domain features for your customers? The MCP Server lets you wire 101domain into the same AI tools your team already uses. See Configuration by AI Client and Custom AI Agent Development for connection details.
Community SDKs
Build faster with a language SDK
Two open-source SDKs wrap the 101domain API in clean, idiomatic interfaces — handy when you're integrating domain features into your own product. They cover domains, DNS, TLDs, products, and account data, and are updated regularly.
These are community-maintained libraries that 101domain is happy to promote, but they are not official 101domain SDKs and are not officially supported. For issues with an SDK, please use its GitHub repository.
