Base URL Overview - Alibaba Cloud Model Studio - Alibaba Cloud Documentation Center

The Base URL is the endpoint for calling model APIs. A Base URL must be used together with an API Key from the same billing plan; otherwise, a 401 error occurs. API Keys are independent across regions and cannot be used across regions.

Pay-as-you-go

Choose a domain that fits your use case:

DashScope domain (such as dashscope.aliyuncs.com): the existing centralized shared domain. It remains available, but migrating to a workspace-dedicated domain is recommended.
Workspace-dedicated domain ([workspace-id].[region].maas.aliyuncs.com): recommended for production. It provides higher throughput, lower latency, and workspace-level traffic isolation.
Trial domain (trial.[region].maas.aliyuncs.com): for temporary testing and quick validation, with lower rate limits.

DashScope Domain

An API Key from any workspace in the same region can call this domain.
