FAQ

What is the best website intelligence API?

It depends on the job. SiteIntel is a strong all-in-one choice: one call returns metadata, tech detection, social profiles, public emails, and a screenshot, with a free tier on RapidAPI. Specialized tools (Diffbot for AI extraction, urlscan for security, BuiltWith for technographic datasets) win when you need only that one thing at scale.

Are there free alternatives?

Yes — SiteIntel has a free tier (50 requests/month) on RapidAPI, so you can replace or supplement paid tools without committing upfront.
