# List the caller's Assets

GET https://api.morphiaone.ai/v1/assets

The caller's readable assets (not expired, not deleted), newest first:
`(created_at, id)` descending, a total order. Each item is exactly the `Asset`
`GET /v1/assets/{asset_id}` answers; a list never carries an `href`. Pages are
chained with `next_cursor`, which is opaque and bound to this query's filters
and to the caller: send it back with the same filters (any `limit`), or the
answer is `400 INVALID_CURSOR`. An unknown or repeated parameter, or a value
out of range, is `400 INVALID_REQUEST` naming the parameter. Served only where
list endpoints are enabled for your environment. Requires no product scope.

Reference: https://docs.morphiaone.ai/api-reference/endpoints/assets/list
