@Kathy I am having the same issue on my end. I can see another user reporting this as well: https://community.cloudflare.com/t/browser-rendering-json-with-custom-ai/854912

Have tried using the Browser Rendering REST API, but it isn't working. The Workers API binding works fine, and I have created a new API token with Browser Rendering Edit perms. I can confirm that using a different token gives an auth error. Doesn't work with either a URL or HTML body param

1984 Ford Laser•11/18/25, 6:17 AM

Also, in the Workers binding, is it normal for it to take 7-10 seconds to get a screenshot response for a very simple HTML page hosted on CF?

Were you able to find a solution? The custom AI provider feature doesn't work

I can't get it to work with openai's models. Haven't tried gemini yet. I always get the following error:

  "success": false,
  "errors": [
    {
      "message": "Unable to form JSON based on user prompt and/or webpage text. Please try with a different prompt try passing a response_format."

}

Hi, could anybody give a sample usage about the snapshot API (https://developers.cloudflare.com/api/python/resources/browser_rendering/subresources/snapshot/methods/create/) ?
I wanna add the "full_page" and "type" to request, but I always get a error:

I have tried these 2 request body ,but not work either:

{
    "url": "https://www.bbc.com/",
    "screenshot_options":  {"full_page" : true , "type":"webp" }
  }

{
    "url": "https://www.bbc.com/",
    "screenshot_options":  {"full_page" : true , "type":"webp" }
  }

{
    "url": "https://www.bbc.com/",
    "screenshot_options":  {"full_page" : true , "type":"webp" }
  }

{
    "url": "https://www.bbc.com/",
    "screenshot_options":  {"full_page" : true , "type":"webp" }
  }

{
    "url": "https://www.bbc.com/",
    "full_page" : true , 
    "type":"webp" }
  }

{
    "url": "https://www.bbc.com/",
    "full_page" : true , 
    "type":"webp" }
  }

{
    "url": "https://www.bbc.com/",
    "full_page" : true , 
    "type":"webp" }
  }

{
    "url": "https://www.bbc.com/",
    "full_page" : true , 
    "type":"webp" }
  }

I got this error:

{
    "errors": [
        {
            "code": "unrecognized_keys",
            "keys": [

            ],
            "message": "Unrecognized key(s) in object: 'screenshot_options'"
        }
    ],
    "success": false,
    "result": {}
}

    "errors": [
        {
            "code": "unrecognized_keys",

            ],
            "message": "Unrecognized key(s) in object: 'screenshot_options'"
        }
    ],
    "success": false,
    "result": {}
}

            ],
            "path": [

            ],
            "message": "Unrecognized key(s) in object: 'screenshot_options'"
        }
    ],
    "success": false,
    "result": {}
}

{
    "errors": [
        {
            "code": "unrecognized_keys",

                "screenshot_options"
            ],
            "path": [
                "body"
            ],
            "message": "Unrecognized key(s) in object: 'screenshot_options'"
        }
    ],
    "success": false,
    "result": {}
}

How should I fix it ? Thanks

you're running POST @ /accounts/{account_id}/browser-rendering/snapshot right?

KathyOP•12/1/25, 6:03 PM

think issue might have been you were in python docs so you got

screenshot_options

screenshot_options

instead of

screenshotOptions

screenshotOptions

It's definitely coming from Browser Rendering - the uuid also matches up with my BR logs. I'm invoking using

await puppeteer.launch(env.BROWSER)

await puppeteer.launch(env.BROWSER)

so it shouldn't even be trying to connect to an existing session.

The
