Start with your goal

Extruct API gives you three ways to discover companies, Deep Research for cited reports on companies and people, and AI Tables for enrichment and scoring on either Extruct results or your own company list. Use:
  • Semantic Search for fast, recall-first search over the Extruct index.
  • Lookalike Search when you already have a representative company domain or UUID.
  • Deep Search when you need a more deliberate shortlist scored against custom criteria.
  • Deep Research when you need a deep, cited report on one research target — a company, a person, or a team: account plans, lead and buyer research, diligence.
  • AI Tables when you want to enrich, score, and review a company list in a reusable workflow.

Lookalike Search

Start from a company domain or UUID and find similar companies ranked from the Extruct index.

Semantic Search

Start from a natural-language query and retrieve matching companies instantly from the Extruct index.

Deep Search

Run asynchronous, agent-based discovery that ranks companies against natural-language criteria using web, Extruct DB, Maps, and LinkedIn.

Deep Research

Submit a detailed research brief about a company, a person, or a team and get back a cited report — markdown or structured to your own schema.

AI Tables

Start with companies from Extruct or from your own company list, then run repeatable enrichment and scoring workflows.
