200 company lookups/mo

The name on the invoice, not the one in the logo.

The legal entity behind a domain, read from its structured data, footer and legal pages.

  1. The legal entity, not the wordmark

    Returns "Stripe, Inc." for contracts, with "Stripe" alongside it for people.

  2. Published contacts, ready to route

    Public emails and addresses as the business lists them, returned as arrays.

  3. Founded, headcount and parent company

    Founding year, size and owner, so a subsidiary is never mistaken for the group.

Look up companies with Claude

Ask who is behind any domain, or send the same request with your API key.

# claude.ai/directory/prefetch → Connect
# Sign in to Prefetch, Allow access. No key to paste.
# Claude Code on the same Claude account has it too.

# Then just ask:

  Run prefetch_company on stripe.com and tell me the
  legal entity and how to contact it.

What teams build with the Company API

  • Enrich at signup

    Take the email domain a user signs up with and fill in the company name before they ever see a form field asking for it.

  • CRM hygiene

    Backfill and de-duplicate account records at scale with the legal name, trading name, size and headquarters behind every domain.

  • Vendor & KYB onboarding

    Confirm the entity behind a supplier domain and capture the published address and contact inbox as part of the intake trail.

  • Agent tooling

    Give an LLM agent a factual company record to work from instead of letting it browse and guess one.
