# Generate Front Book Cover
Self-publishing authors and digital bookstores use this recipe to generate a professional front book cover. Define a canvas with a gradient background, add title and author text — ready for ebook stores, print-on-demand, or preview thumbnails.
## APIs Used
Image Generation (1 credits/request)
## Prerequisites
You need an Iteration Layer API key. Get one at [platform.iterationlayer.com](https://platform.iterationlayer.com) during the 7-day trial.
For full integration guidance (SDKs, auth, MCP, error handling), see the [Iteration Layer Integration Guide](https://iterationlayer.com/SKILL.md).
## Implementation
```bash
curl -X POST https://api.iterationlayer.com/image-generation/v1/render \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
