Hello,

Welcome to Microsoft Q&A,

To retrieve a list of custom models from Azure Translator – Custom Translator, you’ll need to use the Custom Translator REST API, which is a separate service from the standard Translator Text API.

Endpoint to List Custom Models

GET https://customtranslator.azurewebsites.net/api/models

https://learn.microsoft.com/en-us/azure/ai-services/translator/text-translation/reference/v3/reference

I tried this endpoint, but I'm getting a 'Not Found' error. I'm passing the Ocp-Apim-Subscription-Key in the headers. Is there anything else I need to include, and does this endpoint vary by region?

Hi Manish Pal

You can list Custom Translator models using the Azure Cognitive Services REST API by making a request.

The request typically follows this format:

GET https://api.cognitive.microsofttranslator.com/custom/models?api-version=3.0

Ocp-Apim-Subscription-Key: Your Azure Translator subscription key.

Content-Type: application/json

The API will return a list of models with details such as model ID, status, and language pair.:

Thank You.
