# Asset Metadata

This API allows you to get full **metadata** of a blockchain asset, including both **on-chain** information (data stored on the blockchain) and **off-chain** information (documents stored in DocumentDB). Metadata provides all the details needed to verify the authenticity and integrity of the asset.

The user can request metadata by providing the **unique asset ID**.
