# Introduction

The Domain Exposure API summarizes credential exposure associated with a domain over the previous 12 months.

The report combines two types of compromised credential data:

- **Data breaches** — credentials exposed through breaches, database dumps, and combo lists.
- **Infostealer logs** — credentials collected from malware-infected devices.

It also distinguishes between two types of exposure:

- **Employee exposure** — compromised accounts associated with the organization's domain.
- **Client exposure** — compromised users found logging into services belonging to the domain.

For example, a compromised `@example.com` employee account would contribute to employee exposure. A compromised Gmail user whose infostealer log contains credentials for `example.com` would contribute to client exposure.

The API returns aggregated statistics rather than individual credentials or personally identifiable information.

## Terms of use

The Domain Exposure API is completely free to use. No account, API key, or access token is required, and there is no defined rate limit. As with any public page or service operated by [Webz.io](http://Webz.io), abusive traffic from a single IP address, such as excessive automated requests that resemble a denial-of-service attack, may be blocked or restricted. When using data from the API publicly, a link to [LunarCyber.com](http://LunarCyber.com) as the data source is appreciated, but attribution is not required.
