+            This space demonstrates an issue with the Gradio API related to file donwloads.  
+            You can use any preferred HTTP client to reproduce the issue. Refer to the sample code below.  
+            **Problem**: The file URL returned by the Gradio API is incorrect.  
+
+            
+            this a sample curl code:
+            ```bash
+            space="https://rrg92-gradioapibug.hf.space"; curl -X POST "$space/call/GetFile" -s -H "Content-Type: application/json" -d '{"data":[]}' | awk -F'"' '{print $4}' | { read event; curl -s "$space/call/GetFile/$event" | grep -oEi '"url": ".*?"' | awk -F'"' '{print $4}'  ;    }
+            ``` 
+            
+            
+            this is same version, but can run in Powershell
+            ```posh
+            $space = "https://rrg92-gradioapibug.hf.space"; iwr -met POST -Uri "$space/call/GetFile" -Body '{"data":[]}' -ContentType "application/json" | ConvertFrom-Json | %{ $_.event_id }  | %{  iwr -uri "$space/call/GetFile/$_" } | %{$null=$_.content -match "data: (.+)"; $matches[1] } | ConvertFrom-Json | %{ $_.url}
+            ```
+            
+            The sample code is supposed to output a URL path to a file generated by the Gradio API. However, if you try to access the link, it returns a "not found" error.  
+            The issue arises because the 'url' field returned by the API is incorrect. It should follow the format: `HOST/FILE=PATH`, but it returns a different path.  
+
+            In my tests, I couldn't determine the exact path, but for example, it returns something like `HOST/c/file=PATH`.  
+            In other cases, I've seen it return paths such as `HOST/call/ApiName/file=PATH`.
