## API Endpoint

Base URL: https://api.core.today/v1

### Create Prediction
POST /predictions

### Get Status
GET /predictions/{job_id}

### Cancel
DELETE /predictions/{job_id}

## Authentication

Header: `X-API-Key: YOUR_API_KEY`

## Input Parameters

- `aspect_ratio` (string, optional): Aspect ratio of the generated image. (Default: `1:1`; Options: `1:1`, `4:3`, `3:2`, `16:9`, `2.35:1`, `4:5`, `2:3`, `9:16`)
- `style_reference_images` (array, optional): Up to 10 reference images whose style should be transferred to the output. Their style is extracted and applied with the strength controlled by `style_reference_strength`. (Default: `[]`)
- `moodboard_strength` (number, optional): How strongly the moodboard shapes the output. (Default: `0.35`; Range: min: 0, max: 1)
- `style_reference_strength` (number, optional): How strongly to apply the style of the reference images. 0 means no influence, 1 means the style dominates. Applied to all style reference images. (Default: `0.5`; Range: min: 0, max: 1)
- `seed` (integer, optional): Random seed. Set for reproducible generation.
- `moodboard_id` (string, optional): Optional Krea moodboard UUID. Moodboards must first be created in the Krea webapp (https://www.krea.ai/moodboards). Get the UUID from the moodboard share URL: `?share=<uuid>`.
- `creativity` (string, optional): How far the model expands on your prompt. 'raw' renders only what you describe; 'low' fills in obvious gaps; 'medium' adds reasonable interpretation; 'high' takes meaningful creative liberty. (Default: `medium`; Options: `raw`, `low`, `medium`, `high`)
- `prompt` (string, **required**): Text prompt describing the image.
