Do you manage many domains? Do you work in an agency, develop platforms, or simply need to save time on repetitive tasks?
Then this is for you: with the cdmon domain API, you can connect your tools directly with our platform and work magic from your own company without needing to connect to external control panels✨.
Forget about going to the commercial website and then to the control panel every time you want to register, renew, or check a domain. Now you can do it all via API, simple and fast.
Our API is an interface that allows you to automate the management of your domains from your own system, tool, or development.
With it, you can (among other things, because it is a hyper-complete tool)
- Register new domains
- Renew existing domains
- Check availability in real-time
- Get detailed domain information
- Manage DNS and basic configurations
All without needing to click on the panel. Just code and requests. You know what’s best? It’s completely FREE and you can even benefit from our volume discounts.
Who is it for?
- 🙆♂️ Companies or agencies that manage multiple client domains
- 👩💻 Developers who want to integrate purchase and renewal processes into their systems
- 🧩 Integrators of custom panels, apps, or own tools
- 🏗️ Hosting platforms, site builders, marketplaces… that need to connect domain registration automatically
- 🙋For those who want to become a small cdmon but do not want to invest in having the necessary infrastructure.
What problems does the cdmon domain API solve?
Our domain API is not just a tool for technicians: it is a solution designed to automate, scale, and professionalize domain management.
Whether you are an agency, a freelancer, a platform, or someone who manages many domains, this is what it takes off your shoulders:
Tired of doing repetitive tasks from the panel?
If you work with many domains, you know what it’s like to have to enter, click, change a DNS, check an expiration date, renew… over and over again.
✅ The API allows you to automate all that from your own system. You can launch a registration, a renewal, or a DNS modification in seconds, without having to open the browser. All by code, all from your workflow.
Do you waste time checking domains one by one?
Having to check the expiration date, availability, or status of each domain from the panel can become a tedious task.
✅ With the API, you make a massive call and get the information of all your domains instantly. You can integrate it into your own dashboard or internal tool and always have it updated.
Do you need to renew domains without forgetting or making mistakes?
In manual management, it’s easy to miss one, and with that, you can lose a domain you care about or that is important to you.
✅ The API would allow you to schedule from your system or launch automatic renewals in a massive and planned way. You can even link it with your billing system or CRM so that only domains with confirmed payment are renewed, just to give you ideas 😊.
Would you like to offer registration services to your own clients without setting up complex infrastructure?
This is one of the biggest benefits: if you want to offer domain registration from your website, platform, intranet, or app, you can do it by integrating our API.
✅ This way, you can become a kind of «mini cdmon» white label, offering registration and renewal services to your clients without having to maintain infrastructure, DNS servers, accreditation processes with each TLD, or worry about the technical part.
You focus on your client. We do the background work.
Do you need a secure way to interact with your domains?
With so many integrations, security is key.
✅ Our API works with token authentication (API Key), so you have everything under control. In addition, you can revoke, regenerate, or monitor the use of your API key at any time.
Do you want to have all management integrated into your own system?
Using external tools is fine… until you need them to talk to each other.
✅ With the API, you can connect your client manager, your ERP, your CRM, or your own hosting panel directly with cdmon. This way, everything flows without jumping between windows. Your team works from one place, and everything stays synchronized.
Are you short on time or human resources?
Manual management does not scale: if each client or domain needs human intervention, your team quickly becomes overwhelmed.
✅ By automating basic tasks with the API, you can scale your operation without needing to increase staff. You no longer need an entire team for tasks like renewing 50 domains, checking expiration dates, or reconfiguring DNS entries.
Do you want to innovate without reinventing the wheel?
There are many business or service ideas that can benefit from domain registration: website builders, eCommerce platforms, CRMs for agencies, service marketplaces, etc.
✅ The API gives you professional access to the backend of a real registrar (cdmon), with all its power, without having to build anything from scratch.
Are you afraid of the price it might have?
If you think the price for having a tool like this is high, you can be completely at ease.
✅ The API is completely free for all our clients
Domain API: First steps
Log in to your cdmon control panel and go to the «Domain API» section, located at the top within the product menu.
The domain API is disabled by default for all users, so you will need to activate it manually.

You will receive a two-factor verification code in the email associated with your control panel account. This measure ensures that activation or deactivation is only done when you really need it.

After entering the two-factor code, you will be able to use the domain API. Note that, for security reasons, your API Key will be shown only once. Make sure to save it in a safe place.

Usage example:
Summarizing the above, to use the cdmon domain API you must:
- Be a cdmon client with an active domain.
- Access your panel and generate your API key in the «Domain API» section.
- Consult the official documentation (available only in Spanish) with all available endpoints.
- Start automating tasks like registering domains, renewing them, or checking expiration dates.
An example of how to make a request to check if a domain is available
Suppose you want to know if the domain myexampledomain.com is available.
Here is an example of how to make that request with curl:
| curl -X GET ‘https://api.cdmon.com/v1/domains/check?domain=myexampledomain.com’ -H ‘Authorization: Bearer YOUR_API_KEY’ |
Frequently asked questions about the domain API
What can I do exactly with the cdmon domain API?
The API allows you to perform virtually all the management you would do from the control panel, but automatically: search for available domains, register them, renew them, modify them, manage DNS, check expiration dates, and much more. All from your system, without needing to manually access the panel.
What do I need to start using the API?
You only need to be a cdmon client and have a contracted domain. Then you access your control panel, go to the «Domain API» section, generate an API key, and you can start. In addition, you will have access to all the technical documentation with examples and endpoints ready to use.
Can I integrate the API with my own software? (ERP, CRM, online store…)
Of course! That’s the idea. The API is designed so you can connect it with any system you use, as long as it can make requests. It is perfect for integrators, companies with their own platforms, agencies, resellers, or anyone who wants to have control from their own environment.
Is the API available in multiple languages or only in Spanish?
The API works with standard JSON requests, so it is not limited by language. The help documentation and the cdmon panel are in multiple languages (Spanish and English), but the important thing is that the language of the API is universal: it is made for developers, regardless of the language they speak.
Is there any cost or usage limitation?
The API is completely free for cdmon clients. There are usage limits to prevent abuse (as with any API), but they are designed to allow professional use. If you have more advanced needs or very high volume, you can contact us to consider extensions.
Can I use the API to create my own domain registration website?
Yes. Many clients use the API to resell domains on their own websites or projects without having to maintain their own infrastructure. It’s like having a «mini-cdmon» adapted to your brand, with the technical and systems support of cdmon behind it. Ideal for platforms, communities, associations, SaaS tools, or online academies. However, you will need to contact us to agree on the terms and conditions, as you will be subject to certain ICANN regulations.
Can I combine the use of the API with my volume discounts?
Yes. Using the API does not cancel any promotion. In fact, if you have active volume discounts on your account (in domains, for example), you will continue to benefit from those prices when registering or renewing through the API. You automate and also save. 🔥
Is it limited to a programming language?
Of course not, any language with HTTP support is compatible. It’s just a matter of how comfortable you feel programming your system.
The cdmon domain API is the fastest, most secure, and scalable way to manage multiple domains from your own system.
You no longer need panels, clicks, or wasting time on repetitive tasks. Automate and save.
