# Queries Details About an Image

#### Scenario

Details about a private or public image can be queried.

The token obtained from IAM is valid for only 24 hours. If you want to use a token for authentication, you can cache it to avoid frequently calling the IAM API.

#### Involved APIs

If you use a token for authentication, you must obtain the token and add X-Auth-Token to the request header of the IMS API when making an API call.

- IAM API used to obtain the token

  URI format: POST https://IAM endpoint/v3/auth/tokens

- IMS API used to query image details (Native OpenStack API)

  URI format: GET https://IMS endpoint/v2/images/Image ID

#### Procedure

1. Obtain the token.
2. Send GET https://IMS endpoint/v2/images/Image ID.
3. Add X-Auth-Token to the request header.

   An example request is as follows: https://IMS endpoint/v2/images/33ad552d-1149-471c-8190-ff6776174a00.

4. Refer to "Querying Image Details (Native OpenStack API)" in Image Management Service API Reference for parameter descriptions and response details.

   For details about status codes for request exceptions, see Status Codes.
