Endpoint URL
POST http://127.0.0.1:5000/itt
Request Format
- Method: POST
- Content-Type: multipart/form-data
- Body Parameters:
- image (required): The image file to be processed. The image is encoded and used by the Moondream model.
- prompt (required): A text string included as form data. This text is used as a prompt for the model to generate a response based on the provided image.
Success Response
- Condition: If the image and prompt are processed successfully.
- Code: HTTP 200 OK
- Content: A JSON object containing the text response generated by the model. The object includes a key ’text’ with the response as its value.
Error Response
- Condition: If the request is missing either the image file or the prompt, or if an error occurs during processing.
- Code: HTTP 400 Bad Request
- Content: A JSON object containing an error message.
