DALL-E 3 Image Generation

OpenAI DALL-E 3 API

Here are the official API parameters and response format:

Body

{
    "model": "dall-e-3",
    "prompt": "A cute baby sea otter",
    "n": 1,
    "size": "1024x1024"
}

Response

{
  "created": 1589478378,
  "data": [
    {
      "url": "https://..."
    },
    {
      "url": "https://..."
    }
  ]
}

Workflow Design

Use AI to optimize the image generation prompt (skipped here — use your own prompt).
Use the HTTP Request module to call the DALL-E 3 API and retrieve the image URL.
Use the Text Editor module to construct a Markdown image tag.
Use the Specified Reply module to output the image link directly.

1. Build the HTTP Module

Copy the DALL-E 3 API request parameters and replace prompt with a variable. You also need to add a Headers.Authorization header.

Body:

{
    "model": "dall-e-3",
    "prompt": "{{prompt}}",
    "n": 1,
    "size": "1024x1024"
}

Headers:

Authorization: Bearer sk-xxx

Response:

Extract the response value based on the DALL-E 3 API return format. Since we only generate one image, we just need the first image's URL. Add a custom output data[0].url to the HTTP module.

2. Text Editor — Build Image Link

In Markdown syntax, ![image description](image URL) inserts an image, where the image URL comes from the HTTP Request module output.

Add an input to receive the image URL from the HTTP Request module, then reference it as a variable in the Text Editor module to produce a complete Markdown image tag.

3. Specified Reply

The Specified Reply module outputs incoming content directly to the client, so it can render the processed Markdown image format as-is.
