Similar Companies API FAQs

What is the Similar Companies API?
The Similar Companies API finds companies that closely resemble a given target company by understanding their business model, context, and what they actually do — not just surface-level attributes. Powered by AI.
How does the similarity matching work?
Our AI model analyzes the business model, context, and what a company actually does to compute a similarity score against every company in our database. Results are ranked by relevance and returned with a score between 0 and 1.
What inputs does the API accept?
You can provide a company domain, name, or CompanyEnrich ID as the input. The API will identify the target company and return a list of the most similar companies from our database.
How many similar companies are returned?
By default, the API returns the top 10 most similar companies. You can customize this using the limit parameter to retrieve more or fewer results per request.
Do similar company results include full enriched data?
Yes. Each similar company returned includes a full enriched company profile with 60+ data points — no additional API calls are needed to get detailed company information.
What are common use cases for this API?
Common use cases include building lookalike audiences for sales prospecting, competitive analysis, market research, account-based marketing (ABM), and finding expansion opportunities in adjacent markets.
How much does the Similar Companies API cost?
Pricing is based on our credit system, where each API call has its own credit usage. For the most current and detailed information on credit costs and monthly plans, please visit our pricing page.
Do I get charged if no similar companies are found?
No. You are only charged credits when the API successfully returns similar company results. If the target company is not found in our database, no credits are deducted.
