FAQs

Q: Does it support URL paths? A: No. Only root domains are supported (e.g., example.com). Paths will return invalid results.

Q: What’s the difference between Default and Compact output? A: Default returns an array of objects, while Compact nests the array under "data" to reduce payload size.

Q: How does caching work? A: Successful results are pulled from cache for 90 days unless the store is manually cleared.

Q: Can I run this tool for bulk domain lists? A: Yes, but for very large datasets, use a bulk-optimized workflow to reduce costs.
