Help Needed with Visionati API Request Formatting

steventrust223

Hello Visionati Community,

I'm currently trying to use the /api/fetch endpoint to upload an image for analysis. Despite following the API documentation and trying various configurations using both Postman and Python scripts, I keep receiving the "Invalid request format" error.

Here is what I've done so far:

Endpoint**: https://api.visionati.com/api/fetch
Request Method**: POST
Body**: Using form-data to send the file.
Parameters**:
- file: an image (e.g., IMG_1721.JPG)
  - backend[]: Tried values like "googlevision"
  - feature[]: Tried values like "descriptions"
Authorization**: Bearer token provided in the Authorization tab.

I would really appreciate if anyone could share a working example or provide guidance on what the correct request format should be.

Thanks so much for your help!

Best,
Steven

I would be happy to help. Full docs on the format are at https://docs.visionati.com/#analyze-an-image-video

There are a few things to note:

The file must be base64 encoded or a Data URI. You can't just pass a file object!
Authentication should send the header Authorization: Token <YOUR_API_KEY>
The backend and feature are the correct format, but google vision does not support descriptions! Only openai, gemini, jinaai, claude, llava and bakllava support them!

Here is a simple example in javascript. This is taken from our analyze app.

      prompt = "Whatever prompt you want to use"

      var data = {
        feature: ['descriptions'],
        backend: ['openai']
        prompt: prompt
      };

      file_input = document.getElementById("file");
      file = file_input.files[0];

      if (file.size > 10000000) {
        document.getElementById("apierror").innerHTML = "File too large. Max size is 10MB.";
        document.getElementById("spinner").innerHTML = "";
        return false;
      }

      data.file = await getBase64(file);
      data.file_name = file.name;

      xhttp.open("POST", "/api/fetch", true);
      xhttp.setRequestHeader('Content-type', 'application/json;charset=utf-8');
      xhttp.send(JSON.stringify(data));
