## API Endpoint

Base URL: https://api.core.today/v1
Create Prediction: POST /predictions
Get Status: GET /predictions/{job_id}

## Authentication
Header: X-API-Key: YOUR_API_KEY

## Input Parameters

### Required
- **prompt**: string - Text description of the image to generate

### Optional
- **aspect_ratio**: string (default: 1:1) - Aspect ratio for the generated image
  Options: 1:1, 16:9, 21:9, 3:2, 2:3, 4:5, 5:4, 3:4, 4:3, 9:16, 9:21
- **image**: string - Input image URL for image-to-image mode

- **megapixels**: string (default: 1) - Approximate megapixels for output
  Options: 1, 0.25

## Examples

### Natural Portrait
Generate a photorealistic portrait without AI look
```json
{
  "model": "black-forest-labs/flux-krea-dev",
  "input": {
    "prompt": "Candid photograph of a barista making latte art in a cozy coffee shop, natural window lighting, shot on Canon EOS R5, shallow depth of field",
    "image_size": "portrait_4_3",
    "num_inference_steps": 28,
    "guidance_scale": 3.5
  }
}
```

## Response Format
```json
{
  "job_id": "abc123",
  "status": "pending | processing | completed | failed",
  "result": "URL or data (when completed)"
}
```

## Usage Flow
1. POST /predictions with model and input -> receive job_id
2. GET /predictions/{job_id} -> poll until status is completed or failed
3. Result contains output URL(s)

## Tips
- Describe the scene as if it were a real photograph for best results
- Mention camera models and lens types for extra realism
- Use natural lighting descriptions to avoid the AI look
- Perfect for content that needs to look authentically photographed
