# List your catalogue Looks

GET https://api.morphiaone.ai/v1/catalogue/looks

Your looks, newest first: `(created_at, id)` descending. Pages are chained with
`next_cursor`, opaque and bound to you: send it back unchanged, or the answer is
`400 INVALID_CURSOR`. An unknown or repeated parameter is `400 INVALID_REQUEST`
naming it.
Requires the `catalogue.read` scope, which your account operator provisions; no other
catalogue scope implies it. Served only where the catalogue is enabled for your
environment.

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