Check Bulk Domain Availability and Premium Domain Availability

We need to check the availability of over 500,000 domains, including identifying premium domains available for purchase. There are a couple of services (NameCheap, GoDaddy) that offer bulk domain checks. Based on initial observations, NameCheap seems to handle this task better but has limitations—it allows checking only 8,000–10,000 domains per IP.

Key Requirements:

1) IP Rotation: You’ll need a tool to switch IP addresses to bypass the service’s limitations.
2) Automation: Develop a script in Python, C#, C++, or a language of your choice, or use existing solutions like Xparser, Browser Automation Studio, or Zenoposter.
3) Deadline: The task should be completed within 3–5 days.
4) Output Format: Results should be provided in CSV files.

When submitting your proposal, include the following:

1) Parsing Methodology: Specify the programming language or parser tool you’ll use.
2) IP Resources: State the number of IPs you have at your disposal.
3) Timeline: Indicate how long it will take you to complete the task.
4) Service Confirmation: Confirm which platform (GoDaddy or NameCheap) you will use for the checks.

Once selected, you will need to:

1) Provide a sample script or screenshot showing the parsing process.
2) Share test results in a CSV file to demonstrate the accuracy of your approach.

We look forward to your proposals!
