Request parameters

All parameters are passed through the query string.

Parameter	Type	Required	Description
name	String	No	Fuzzy search by model name. Example: `qwen`
model	String	No	Exact match by model ID. Example: `qwen3-max`
page_no	Integer	No	Page number, starting from 1. Default: `1`.
page_size	Integer	No	Number of models returned per page. Default: `20`.

Response parameters

Parameter	Type	Description
request_id	String	The request ID, used for troubleshooting.
output.total	Number	The total number of models that match the query criteria.
output.page_no	Number	The current page number.
output.page_size	Number	The number of entries per page.
output.quotas[].model	String	The model ID.
output.quotas[].workspace_id	String	The workspace ID.
output.quotas[].model_limit	Object	Account-level rate limits. This represents the overall rate limit cap for the model under the current account. Contains the following fields: `request_limit` (Number): The request rate limit value. `request_limit_period` (Number): The time period for the request rate limit, in seconds. A value of `60` indicates per minute (RPM), and a value of `1` indicates per second (QPS). `usage_limit` (Number): The usage limit value. A value of `null` indicates no usage limit. `usage_limit_field` (String): The usage limit type, such as `total_tokens`. `usage_limit_period` (Number): The time period for the usage limit, in seconds. `async_user_queue_limit` (Number): The maximum number of queued asynchronous tasks. `async_user_concurrency_limit` (Number): The maximum number of concurrent asynchronous tasks.
output.quotas[].workspace_limit	Object	Workspace-level rate limits. You can set individual rate limits for each workspace, but the combined limits across all workspaces cannot exceed the `model_limit`. A value of `null` indicates that no workspace-level limit has been set. Contains the same fields as `model_limit`.

Rate limit details

Model Studio applies rate limits at two levels:

model_limit (account level): The overall rate limit cap for the model under the current account, shared across all workspaces.
workspace_limit (workspace level): You can configure individual rate limits for each workspace. The combined limits across all workspaces cannot exceed the model_limit cap.

Rate limit types

Field	Meaning	Example
request_limit + request_limit_period	Request rate limit	`request_limit=60, request_limit_period=60` means a maximum of 60 requests per minute (RPM). `request_limit=5, request_limit_period=1` means a maximum of 5 requests per second (QPS).
usage_limit + usage_limit_period	Usage limit	`usage_limit=100000, usage_limit_field=total_tokens, usage_limit_period=60` means a maximum of 100,000 tokens per minute (TPM). A value of `null` indicates no usage limit.
async_user_queue_limit	Async queue limit	The maximum number of tasks that can be queued when using asynchronous calls.
async_user_concurrency_limit	Async concurrency limit	The maximum number of tasks that can be executed simultaneously when using asynchronous calls.

Sample requests

Example 1: Query quotas for all models

curl "https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/api/v1/quotas?page_no=1&page_size=100" \
    --header "Authorization: Bearer $DASHSCOPE_API_KEY" \
    --header "Content-Type: application/json"

Example 2: Query quotas for a specific model

curl "https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/api/v1/quotas?model=qwen3-max" \
    --header "Authorization: Bearer $DASHSCOPE_API_KEY" \
    --header "Content-Type: application/json"
