An API key is a credential or identifier used when software accesses a service.

## Why it matters

Keep access credentials out of public website code and repositories.

## Illustrative example

A backend reads a secret key from an environment variable.

## What to check

Some keys are publishable; treat a key according to its provider's documented purpose.

## How Data SDK fits

Data SDK connects website visits with available company details worldwide, from startups to larger businesses. Coverage and fields vary. Start free trial opens an email request; terms are confirmed with the team. The full API is coming soon.

These are suggested workflows, not a list of built-in integrations. Use your own approved analytics, CRM, and research process where needed. Matches and fields vary. A company match does not identify a person or prove buying intent.
