Namesilo Bulk Domain Availability Checker | n8n Workflow Template

Namesilo Bulk Domain Availability Checker n8n Template

This workflow automates the process of checking domain availability for multiple domains using the Namesilo API. It handles large lists by splitting domains into batches of 200, respecting Namesilo's rate limits with automated waiting periods, and outputs the results in a convenient Excel format for easy analysis.

How It Works

1. The workflow begins with a manual trigger and uses the "Set Data" node to define your Namesilo API key and list of domains to check.
2. The "Convert & Split Domains" node processes your domain list, splitting it into batches of 200 domains to respect API limits.
3. The "Loop Over Domains" node processes each batch sequentially.
4. For each batch, the "Namesilo Requests" node sends an API request to check domain availability.
5. The "Parse Data" node processes the API response, extracting availability information for each domain.
6. A 5-minute wait is enforced between batches to comply with Namesilo's rate limits.
7. All results are merged and formatted into a clean structure with domain names and availability status.
8. Finally, the data is converted to an Excel file for easy viewing and analysis.

Benefits

• Check hundreds or thousands of domains in a single automated workflow
• Automatically handles API rate limits to prevent request failures
• Processes domains in optimal batch sizes of 200
• Provides results in Excel format for easy sorting and filtering
• Saves time compared to checking domains manually
• Reusable template that can be easily modified for different domain lists

Requirements

• Namesilo API key (available for free from Namesilo)
• List of domains to check (one domain per line)
• n8n instance to run the workflow

Setup Instructions

1. Download or import the workflow JSON into your n8n instance.
2. Get your free Namesilo API key from https://www.namesilo.com/account/api-manager.
3. Open the "Set Data" node and enter your Namesilo API key in the "Namesilo API Key" field.
4. In the same node, enter your list of domains (one per line) in the "Domains" field.
5. Save the workflow and run it by clicking the "Execute Workflow" button.
6. The workflow will process all domains in batches, waiting 5 minutes between batches.
7. When complete, download the Excel file containing the domain availability results.
