Company Search API

The Company Search API allows you to search our database of over 33 million companies using a combination of firmographic attributes. You can filter by industry, location, company size, revenue, technologies used, and many other criteria to find exactly the companies you're looking for.

A Company Search API is typically used for lead generation, CRM enrichment, market analysis, and building search features within your own product. It enables developers, sales teams, and data platforms to programmatically discover and retrieve detailed company profiles based on specific criteria.

A Company Search API finds companies that match criteria such as industry, location, employee count, or technologies used. A Company Enrichment API retrieves information about a company you already know, using its domain, name, or social profile. Use Search to discover target accounts and Enrichment to fill in existing company records. CompanyEnrich's search results already include enriched company profiles. Our guide to the best company data APIs covers when each type fits.

Yes. CompanyEnrich's MCP server lets compatible AI tools, including Claude and Cursor, search for companies and enrich company profiles. You can also integrate the REST APIs into your own agent's tools to support account discovery, company research, and automated qualification.

Standard company search relies on exact keyword matching against structured filters like industry codes, location, or company name. Semantic search, on the other hand, understands the intent and context behind a natural language query. For example, searching for "eco-friendly packaging startups in Europe" using semantic search will return relevant results even if those exact words don't appear in a company's profile. Our API supports both approaches and they can be combined for maximum precision.

Yes. Our platform uses a vector database to power both semantic company search and our Similar Companies API. Each company profile is represented as a high-dimensional vector, enabling us to match based on meaning and similarity rather than just keywords. This is what allows features like natural language search and AI-powered lookalike company discovery.

Absolutely. The Company Search API includes a technographics filter, allowing you to search for companies based on the technologies they use. For example, you can find all companies using Stripe for payments, HubSpot for marketing, or Snowflake for data warehousing.

The API supports a comprehensive set of filters including: semantic query, industry, location (country, state, city), employee count, revenue range, founding year, company type, categories, technologies, NAICS/SIC codes, and more. You can also use exclusion filters to refine results. For a full list, visit our API documentation.
