Request parameters

Query World list

curl --location 'https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/api/v2/apps/happyoyster-1.0-acting/openapi/v1/worlds?page=1&pageSize=20&status=ready' \
    -H "Authorization: Bearer $DASHSCOPE_API_KEY"

Authorization string (Required)

API Key authentication. Only the primary API Key is supported; it starts with sk-, e.g. sk-xxx. It is typically configured as the environment variable $DASHSCOPE_API_KEY. A temporary API Key (starting with st-) returns 403003.

Query parameters

page integer (Optional)

Page number, defaults to 1. When page <= 0 it is treated as 1.

pageSize integer (Optional)

Items per page, defaults to 20. When pageSize <= 0 it is treated as 20; when greater than 100 it is capped at 100.

status string (Optional)

Filter by build status. Unknown values are not applied as a filter. Allowed values:

generating: building
ready: ready
failed: build failed

mode integer (Optional)

No need to pass this. The list is already filtered to the Acting model, and items[].mode is always 3. If you still pass it and the value is not 3, 400000 is returned.

code integer

Return code. 0 means success; non-zero is an error code.

message string

Error message. null on success.

data object

Response data. null on failure.

Properties

items array

The Worlds on the current page; an empty array when there is no result. Each item contains encryptedWorldId, name, status (generating / ready / failed), mode (always 3), previewUrl (usually null), createdAt, perspective (usually null), creationModel (always simple), and uploadMode (fixed to first_frame).

pagination object

Pagination info. Contains page (current page number), pageSize (actual items per page), total (total number of records), and hasMore (true when page × pageSize < total).

Prerequisite states and call notes

Model filtering takes effect automatically; the list never mixes in Worlds from other models, and items[].mode is always 3.
List items are lightweight snapshots; they do not return images, prompts, resolution, aspectRatio, or refWorldId. When you need the full configuration, call Query World Detail.
When paging, use pagination.pageSize and hasMore from the response; do not assume the requested values are adopted verbatim.
An empty result is not an error; it returns items=[] and the corresponding pagination info.

Error codes

If the model call fails and returns an error, see HappyOyster Error Codes to resolve it.
