What is Google Speech To Text Rest APi Address?

问题

I have got the speech API key as below image depicted but i am unable to find where to request? where is URL given?

1. "http://www.google.com/speech-api/v2/recognize?output=json&lang=en-us&key="+ apiKey;
2. "https://speech.googleapis.com/v1/speech:recognize?key=" + apiKey;
3. "https://speech.googleapis.com/v1beta1/speech:syncrecognize?key=${" + apiKey + "}";

All are i guess wrong as i am getting DNS name resolution error. what is the correct URL (remember i didn't purchase the service yet), where i can find it.

From the documentation you can see you can query https://speech.googleapis.com/$discovery/rest?version=v1 and it will return a result with a json document with all of the API endpoints.
