Quickly check if many domains are available and export the results to Excel. Great for marketers, brand teams, and founders who need to test name ideas fast and share clean results.

The flow starts on a manual run. You enter your NameSilo API key and a list of domains in the Set Data node. A code step splits the list into groups of 200. The Split in Batches node loops through each group. Each group is sent to the NameSilo API with an HTTP Request. The response is parsed to capture domain and availability. A Wait step pauses 5 minutes between loops to respect rate limits. All results are merged, then turned into an Excel file named domain_results.xlsx.

You only need a NameSilo account and API key. Paste domains one per line and run a small test first. Teams can research hundreds or thousands of names without manual lookups. Expect hours saved and fewer errors from copy and paste. Use it for brand audits, product launches, and domain portfolio checks. Setup is simple and the output is ready to share.

• Manual start to control when bulk checks run.
• Set Data node to store the NameSilo API key and a multi line domain list.
• Code step splits domains into groups of 200 for safe batching.
• Split in Batches iterates through each group and keeps state.
• HTTP Request calls the NameSilo availability endpoint for each batch.
• Parse Data step reads the API JSON and extracts domain and availability.
• Wait node pauses 5 minutes between loops to avoid hitting rate limits.
• Results are merged and converted to an Excel file named domain_results.xlsx.

• Reduce manual checks from hours to minutes by batching up to 200 domains per loop.
• Automate over 90 percent of repetitive lookups and formatting work.
• Improve accuracy by removing copy and paste errors in domain status.
• Handle thousands of domains with a built in wait to respect rate limits.
• Produce a clean Excel file that is easy to share with your team.

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You'll need accounts with NameSilo. See the Tools Required section above for links to create accounts with these services.
3. In your NameSilo account, open the API manager page and create an API key. Copy the key to your clipboard.
4. Open the Set Data node in n8n. Paste your NameSilo API key into the provided field. Paste your domains into the Domains field, one per line.
5. Open the Convert and Split Domains code node and confirm the batch size is 200. Adjust only if you understand the rate limits.
6. Open the HTTP Request node and confirm the URL includes your API key expression and the batched domains placeholder. If you prefer credentials, double click the node, choose Credential to connect with, click Create new credential, then follow the on screen steps to store your API key as a query parameter.
7. Click Execute workflow to run from the Start node. Watch the execution list to see each batch process.
8. Expect a 5 minute pause between loops due to the Wait node. This keeps requests within NameSilo limits.
9. After all batches finish, open the Convert to Excel node output. Download the domain_results.xlsx file from the binary data panel.
10. Validate with a small test list of 5 to 10 domains. Confirm the Availability column matches manual checks on a few items.
11. Troubleshoot common issues: If you see an error in Parse Data, verify the API response is valid JSON and your key is correct. If requests fail, wait and try again to avoid rate limits. If the Excel file is empty, check the Merge Results and ensure fields Domain and Availability are present.
