Language API version 2023-01-01-preview is not available

Hello Stas Khirman,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

Regarding your issues, instead of, no definitive check that your endpoint/resource kind was the cause and to avoid any speculative region/sku/feature names. The below is the way out orderly:

1. Step A: Start by confirming the resource kind and endpoint via Azure Portal (Overview blade) or Azure CLI:

      az cognitiveservices account show \
        --name <your-resource-name> \
        --resource-group <your-rg> \
        --query "{kind: kind, endpoint: properties.endpoint, sku: sku.name}" \
        -o json
   

   If your resource isn’t of kind AIServices or specifically an Azure AI Language resource, the API won’t match. - https://free.blessedness.top/en-us/cli/azure/cognitiveservices/account?view=azure-cli-latest
2. B: Ensure you're using the latest version of the SDK: pip install --upgrade azure-ai-textanalytics Version 5.3.x+ defaults to the stable 2023-04-01 API, which avoids issues caused by older or preview versions. SDK Docs
3. C: Avoid specifying outdated preview versions like 2023-01-01-preview. Let the SDK auto-select or explicitly use 2023-04-01:

      from azure.ai.textanalytics import TextAnalyticsClient
      from azure.core.credentials import AzureKeyCredential
      client = TextAnalyticsClient(endpoint="<your-endpoint>", credential=AzureKeyCredential("<your-key>"))
      result = client.recognizepiientities(["שמי דוד ואני גר בתל אביב. הטלפון שלי הוא 055-1234567"], language="he")
   

   This ensures compatibility with your resource and avoids version mismatch errors.
4. D: Use curl to check if the preview version is supported:

      curl -X POST "https://<your-resource>.cognitiveservices.azure.com/language/analyze-text/jobs?api-version=2023-01-01-preview" \
        -H "Ocp-Apim-Subscription-Key: <your-key>" \
        -H "Content-Type: application/json" \
        -d '{"displayName":"PII Test","analysisInput":{"documents":[{"id":"1","language":"he","text":"שמי דוד… 055-1234567"}]},"tasks":[{"kind":"PiiEntityRecognition","taskName":"pii1"}]}'
   

   If you get a 400/404 error, the preview version isn’t supported in your region or by your resource. REST Docs
5. E: If your current resource doesn’t support the needed API, create a new one with kind AIServices in a supported region:

      az cognitiveservices account create \
        --name my-language-resource \
        --resource-group my-rg \
        --kind AIServices \
        --sku S0 \
        --location westus2 \
        --yes
   

   This ensures full compatibility with the latest Azure Language APIs. Create Resource Guide
6. F: Only register subscription-level previews if explicitly mentioned in Azure docs. Use:

      az feature register --namespace <namespace> --name <feature-name>
   

   Avoid guessing feature names and check the official documentation first. - https://free.blessedness.top/en-us/azure/azure-resource-manager/management/preview-features
