How a lookup works

1

We crawl

Our crawler visits the homepages of every registered domain we know of and keeps the page source and response headers.

2

We match

Thousands of technology signatures run over the page: script addresses, HTML markers, headers, cookies, meta tags and version strings.

3

You look up

The result is stored per domain, so a lookup answers instantly; a domain we have not seen is fetched live and added.

The same lookup in the API

Everything on this page is available as JSON for your CRM, enrichment pipeline or lead-scoring: one request per domain with a Bearer token. Each lookup costs one credit; a free account has 100 credits a month, the plans include 1,000 to 20,000. Unknown domains are fetched live by the API too, and a failed fetch is not charged.
