What kind of data can I get from a company information API?

You can get a lot of different info from company information APIs.

Usually, they’ll work to enrich your company name data with more qualitative information, such as financial statements or full company profiles, if you’re missing contact data for prospecting, etc.

Is using an API suitable for compliance needs?

As long as your data provider is GDPR/CCPA compliant, then using their API will meet compliance needs.

What’s the difference between DaaS providers and standalone APIs?

A standalone company data API is a direct tool for querying or enriching datasets, giving developers access to company information in a structured format like JSON. It’s focused, lightweight and best suited to specific integration needs.

A DaaS provider goes further by offering a managed ecosystem: multiple delivery options (API, flat files, cloud), continuous validation and compliance features, and advisory support.

While APIs give you raw access to data, DaaS provides a broader, ongoing service designed to ensure data quality, regulatory alignment and long-term value.
