Finding high‑quality expired domains is one of the smartest ways to boost SEO, build authority sites, and create valuable backlink assets. DomCop is already popular for its massive expired‑domain database—but its API takes things to the next level. With the DomCop API, you can automate searches, filter domains in real time, and integrate domain metrics directly into your SEO workflows or custom tools.
In this complete guide, you’ll learn what the DomCop API is, how to use it, and how to automate your expired‑domain research like a pro.
What Is the DomCop API?
The DomCop API allows developers and SEO users to programmatically access DomCop’s expired and expiring domain database. Instead of manually browsing the dashboard, the API delivers domain metrics—such as Moz DA, Majestic TF, backlinks, CPC, and age—straight to your own scripts or applications.
It’s ideal for:
-
Automated domain filtering
-
Building internal SEO dashboards
-
Real‑time expired domain alerts
-
Bulk domain analysis
-
Integrating metrics into scraping tools or PBN builders
How to Access the DomCop API
To use the API, you need a DomCop Pro, Guru, or Business plan, as API access isn’t available on lower‑tier subscriptions.
Steps to get API access:
-
Log in to your DomCop account
-
Go to Settings → API Access
-
Copy your API key and the base endpoint URL
-
Review the API documentation for request formats and parameters
Your API key is required for authentication in every request, so keep it secure.
DomCop API Endpoint Structure
DomCop API requests usually follow this format:
You can filter domains by:
-

-
Minimum Majestic TF or CF
-
Backlink count
-
TLD (.com, .net, .org, country domains)
-

-

This flexibility allows you to fetch exactly what you need without sifting through thousands of irrelevant domains.

This returns a JSON file containing domain names and all related metrics.
Using the API for Automation
Here’s how SEO users typically automate workflows:
1. Automatically Search for High‑Authority Domains
Run scheduled scripts (Cron jobs) to check for domains daily.
2. Export Domain Lists to Google Sheets or Excel
Use JSON parsing to automatically update your domain spreadsheet.
3. Integrate Data With SEO Tools
Developers often combine DomCop API with:
-
Ahrefs API
-
Majestic API
-
Domain registrar APIs (Namecheap, Dynadot, GoDaddy)
This allows full automation—from discovery to purchasing.
4. Build a Custom Domain Alert System
Trigger an email or Telegram alert when a domain matches your filters, such as:
-
TF > 20
-
DA > 30
-
Price < $100
Final Thoughts
The DomCop API is perfect for SEOs who want consistent, scalable, and accurate expired‑domain research. Whether you’re building private blogs, flipping domains, or powering SEO tools, the API saves massive time and ensures you never miss valuable opportunities.
