# List image buckets

> Image Library S3 bucket connections (Registries → Image buckets tab).

**Authorisation:** `registry:List` on `krn:celum:registry:image-bucket:*`.

**Assistant tool:** `list_image_buckets`



## OpenAPI

````yaml /openapi.json get /api/image-buckets
openapi: 3.0.3
info:
  description: >-
    The HTTP surface of the Celum backend, generated from its own router and

    authorisation map — so this list cannot drift from the server that serves
    it.


    **Every operation states the IAM action and resource it is authorised

    against.** That pairing is the part worth reading: a policy naming the right

    action against the wrong resource matches nothing, and fails silently.


    Request and response bodies come from the Go types the handlers send and

    decode. Where those types do not determine the shape (an interface, a

    map[string]any, an unknown custom encoding), the operation says so in

    `x-celum-schema-gap` instead of carrying a guessed schema.
