# AbilityInfo

The **AbilityInfo** module defines the ability information. A system application can obtain the ability information through [bundleManager.queryAbilityInfo](js-apis-bundleManager.md#bundlemanagerqueryabilityinfo). The input parameter [abilityFlags](js-apis-bundleManager.md#abilityflag) specifies the information to be contained in the returned [AbilityInfo](js-apis-bundleManager-abilityInfo.md) object.

> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
