Frequently asked questions

What is Company data API?

Company Data API (application programming interface) is a software that is designed to retrieve data upon getting requests. Database APIs, more largely, require software libraries, which are collections of resources that help configure data, provide subroutines, and fulfill requests.

How does Company data API work?

Company data API works by fulfilling a company lookup requested by a user. First, users input specific URLs or a company name, then the software library provides detailed information on retrieving all of the available data requested from the API endpoints. Company data API will then retrieve said data back to the end-user.

Why is Company data API important?

Company data API is important because it allows businesses and investors to discover deeper insights about employee information and companies quickly and easily. Additionally, many Database APIs offer end-users the ability to filter through any retrieved data. For instance, Coresignal’s Company data API can filter specific parametric filters, such as location, industry, size, job title, or specific keywords.
