I'll create a logo generator application that uses Replicate's AI model to create SVG logos based on your description. Let's build this step by step.

First, we need to set up the API route that will handle the logo generation:

This application uses Replicate's AI model to generate SVG logos based on your description. Here's how it works:

1. The API route (/api/generate) uses the AI SDK with Replicate to generate an SVG logo based on the provided prompt.
2. The frontend provides a textarea for entering or editing your logo description.
3. When you click "Generate Logo", it sends the prompt to the API and displays the resulting SVG.
4. You can download the generated SVG file with the "Download SVG" button.

The application comes pre-filled with your detailed logo description, so you can click "Generate Logo" right away to see the results. You can also modify the description to refine the logo design.

To use this application, you'll need to:

1. Set up your Replicate API credentials as environment variables
2. Deploy the application to Vercel or run it locally

Would you like me to explain any specific part of the implementation in more detail?

I see the issue. The error AI_LoadAPIKeyError indicates that the Replicate API key is missing. Let's fix this by adding proper error handling and guiding the user to set up the required environment variable.

The error you're seeing is because the application is missing the Replicate API key. I've updated the code to:

1. Check for the presence of the REPLICATE_API_TOKEN environment variable
2. Provide a clear error message when the API key is missing
3. Add a helpful guide for setting up the Replicate API key

To make this work, you'll need to:

1. Sign up for a Replicate account
2. Get your API token from the Replicate dashboard
3. Add it as an environment variable to your project:

You can add this environment variable in your Vercel project settings or in a .env.local file if you're running locally.

The updated code will now show a helpful error message explaining what's missing, rather than just showing a cryptic error.

Please make sure to add the following environment variable to your project:
