 The response will include an `Operation-Location` header, whose value is a unique URL. You use this URL to query the results of the Read operation. The URL expires in 48 hours.
 
 ### Optionally, specify the model version
 As an optional step, see [How to specify the model version](../how-to/call-read-api.md#determine-how-to-process-the-data-optional). For example, to explicitly specify the latest GA model, use `model-version=2022-04-30` as the parameter. Skipping the parameter or using `model-version=latest` automatically uses the most recent GA model.
 ```bash
-curl -v -X POST "https://westcentralus.api.cognitive.microsoft.com/vision/v3.2/read/analyze?model-version=2022-04-30" -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: <subscription key>" --data-ascii "{\"url\":\"https://upload.wikimedia.org/wikipedia/commons/thumb/a/af/Atomist_quote_from_Democritus.png/338px-Atomist_quote_from_Democritus.png\"}"
