How it works

What happens on every call.

The same tool answers over the REST API, the MCP server and the CLI.

  1. / 01

    Public registry data

    We query the regional internet registries for who holds the address block.

  2. / 02

    Company networks only

    Home broadband and mobile carriers return not_found, so you never mistake an ISP for a lead.

  3. / 03

    Chain it

    Pass the domain to scrape_website or domain_to_company for the full profile.

  4. / 04

    Free when it misses

    A miss gives the lookup back.

Call it

One request. One answer shape.
