Log on to the AI Search Open Platform console.
Select the destination region, switch to AI Search Open Platform, and then select the destination workspace.
In the navigation pane on the left, click API keys. On the API keys page, you can find the service endpoint.
NoteCurrently, AI Search Open Platform is available only in the China (Shanghai) and Germany (Frankfurt) regions.

For example, the URL to call the document segmentation service is: {host}/v3/openapi/workspaces/{workspace_name}/document-analyze/{service_id}/async
If you invoke the service over the Internet, the complete URL is as follows:
http://xxxxxxx.platform-xxx-shanghai.opensearch.aliyuncs.com/v3/openapi/workspaces/xxxxxxx/document-analyze/ops-document-split-001/async
