The Companies API offers a highly scalable interface for searching and enriching over 50 million company profiles worldwide. By combining traditional company data with modern AI queries, it solves the problem of outdated or incomplete B2B databases. The bottom line: One of the most efficient and cost-effective APIs for developers who need deep insights into company data without having to build complex scraping infrastructures themselves. The core problem: Data fragmentation in the B2B sector. Companies today face the challenge that company data becomes outdated extremely quickly. A startup founded today is already in a new funding round or has doubled its team tomorrow. Traditional databases often lag behind by months. Furthermore, manually researching over 300 data points per company—from tech stacks to employee numbers—is simply impossible for sales and marketing teams. The solution: One API for everything. The Companies API acts as a central source of information. With just one API call (domain, email, or social URL), the tool returns structured data. This eliminates the need for multiple data providers and drastically reduces integration time for developers.
With access to over 50 million companies, the API offers enormous coverage. Users can retrieve over 300 specific data points, including industry information, headquarters details (such as Paris for the company itself), and detailed company descriptions.
A standout feature in 2026 is the integration of Large Language Models (LLMs). Users can ask the API specific questions about a company, such as: 'What is this company's primary business model?' The API generates a precise response based on the most up-to-date web data. Natural Language Search Instead of building complex SQL-like filters, the search engine API allows queries in natural language. These are automatically converted into filter criteria, which massively simplifies the creation of lead lists.
The pricing model is transparent and credit-based (1 credit is approximately $0.00119 per company). Compared to competitors like Clearbit or ZoomInfo, The Companies API positions itself as significantly more affordable, especially for startups and scaleups.
Integration is facilitated by SDKs for JavaScript, Python, PHP, Go, and Ruby. This underlines the 'Developer-First' approach of the Paris-based team.
