@austin Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
I understand that you are facing an issue with your code that uses the Bing Spell Check API also your Python code returns no output because of the endpoint.
As you rightly pointed it out, Since 10/31/23 Bing Spell APIs created under Azure Cognitive Services are no longer be supported, those APIs are decommissioned and not functioning anymore. Start using the Azure Marketplace to create new instances of Bing Search APIs. More info here.
Please note that the endpoint for Bing spell check is: https://api.bing.microsoft.com/v7.0/spellcheck
Fore more info, see the calling the API article mentioned here.
To check if the issue is with your app or the API itself, please run the below curl command:
curl -H "Ocp-Apim-Subscription-Key: XXXXXXXXXXX" https://api.bing.microsoft.com/v7.0/spellcheck?text=when+its+your+turn+turn,+john,+come+runing&mode=spell
If this works fine, the issue is related to your app which we need to troubleshoot.
I am also sharing the Bing API pricing article if that helps.
Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
