Automate Screenshots with URLBox & Analyze with AI

This n8n workflow provides a framework for automating the process of capturing website screenshots using URLBox and then analyzing those screenshots with OpenAI's capabilities. It's designed to be a starting point for more complex automation, allowing you to easily integrate visual content analysis into your workflows.

What it does

This workflow currently defines the core components for:

1. Manual Trigger: Initiates the workflow execution manually, allowing for testing and on-demand runs.
2. Edit Fields (Set): A placeholder node to define or modify data that will be used in subsequent steps, such as the URL to be screenshotted or parameters for AI analysis.
3. HTTP Request: This node is intended to interact with a service like URLBox to generate a screenshot of a specified URL. It would typically send a request to the URLBox API and receive the screenshot data or a link to it.
4. OpenAI: This node is set up to interact with the OpenAI API. After a screenshot is obtained, this node would be used to send the image (or its URL) to OpenAI for various AI analysis tasks, such as image description, content extraction, or sentiment analysis.
5. Merge: This node is available to combine data from different branches of the workflow, though it is not currently connected in the provided JSON. It could be used to merge the original input data with the results from the screenshot and AI analysis steps.
6. Sticky Note: A descriptive note within the workflow, likely used for documentation or instructions.

Note: The provided JSON defines the nodes but does not include the actual connections between them or specific configurations (like API keys, URLs, or AI prompts). It serves as a blueprint for a workflow that would perform these actions.

Prerequisites/Requirements

To fully utilize this workflow, you will need:

• n8n Instance: A running instance of n8n.
• URLBox Account: An account with URLBox (or a similar screenshot API service) and its corresponding API key for the "HTTP Request" node.
• OpenAI Account: An OpenAI account and an API key for the "OpenAI" node.

Setup/Usage

1. Import the workflow:
   • Copy the provided JSON content.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the "Import from JSON" button and paste the workflow JSON.
2. Configure Credentials:
   • For the "HTTP Request" node, you will need to configure it to connect to your URLBox (or chosen screenshot API) account. This typically involves setting up an HTTP Request credential with your API key.
   • For the "OpenAI" node, you will need to set up an OpenAI credential with your API key.
3. Connect the Nodes:
   • The provided workflow has disconnected nodes. You will need to connect them in the desired sequence. A typical flow would be: Manual Trigger -> Edit Fields (Set) -> HTTP Request (to URLBox) -> OpenAI (for analysis).
   • The "Merge" node can be used if you have multiple data streams to combine.
4. Configure Nodes:
   • Edit Fields (Set): Define the URL you want to screenshot and any other relevant data.
   • HTTP Request: Configure the URLBox API endpoint, method (e.g., POST), headers (including your API key), and body (specifying the target URL and screenshot options).
   • OpenAI: Configure the OpenAI model to use (e.g., gpt-4-vision-preview), the prompt for analysis, and provide the screenshot image (either as a binary file from the previous node or a URL if URLBox returns one).
5. Test and Activate:
   • Run the workflow once using the "Execute Workflow" button on the "Manual Trigger" node to test its functionality.
   • Once confirmed working, activate the workflow to enable it for production use.
