Frequently Asked Questions

How many domains can I check at once?

We recommend batches of up to 100 domains for optimal performance. Larger batches may timeout. For very large checks, split into multiple requests.

What is the request format?

Send a POST request with a JSON body containing a "domains" array of fully-qualified domain names (e.g., "example.com" not just "example").

Are bulk requests faster than individual requests?

Yes! Bulk requests process domains in parallel and use a single HTTP connection, making them significantly faster than sequential individual requests.

Can I use bulk checking for brand monitoring?

Absolutely. Many users check their brand name across hundreds of TLDs to monitor for potential typosquatting or trademark issues.
