Questions people ask
How does it know?
From signatures in the site's public pages (scripts, tags and headers) and from DNS records such as MX (email), SPF (who sends email) and domain verification records that SaaS tools ask companies to add.
Can it miss things?
Yes. It sees only what is public on the website and in DNS. Internal tools that leave no trace there won't show up.
How fresh is it?
Tech stacks change slowly, so answers are cached for a day. The company profile is checked live.
How much does it cost?
$0.01 per lookup, charged only when it succeeds. In Claude or Cursor the first 20 calls a day are free, with no sign-up.
