Function

This API is used to obtain the image list.

This API does not return the complete result at once, but uses pagination.

Pagination

Pagination refers to the function of returning a subset of a group of images, a link to obtain the next set of images, and a link of the set of images. By default, a set contains 25 images. You can also use the limit and marker parameters to paginate through images manually and specify the number of images that can be returned.

The parameter first in the response indicates the URL of the first page of images, and parameter next indicates the URL of the next page of images. When the last page of images is queried, there is no parameter next.

URI

GET /v2/images

You can type a question mark (?) and an ampersand (&) at the end of the URI to define multiple search criteria. For details, see the example request.
If you need the API of the OpenStack Queens release, the request header must contain X-Api-Version. If the value of X-Api-Version is any letter after M in the Alphabet, the API of the Queens release is returned. If the value is M or a letter before M, the API of the Mitaka release is returned.

Table 1 lists the parameters.
