## 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

- `lora_scale_transformer_2` (number, optional): Determines how strongly the transformer_2 LoRA should be applied. (Default: `1`)
- `frames_per_second` (integer, optional): Frames per second. Note that the pricing of this model is based on the video duration at 16 fps (Default: `16`; Range: min: 5, max: 30)
- `lora_weights_transformer` (string, optional): Load LoRA weights for the HIGH transformer. Supports arbitrary .safetensors URLs from the Internet (for example, 'https://huggingface.co/TheRaf7/instagirl-v2/resolve/main/Instagirlv2.0_hinoise.safetensors')
- `seed` (integer, optional): Random seed. Leave blank for random
- `interpolate_output` (boolean, optional): Interpolate the generated video to 30 FPS using ffmpeg (Default: `False`)
- `num_frames` (integer, optional): Number of video frames. 81 frames give the best results (Default: `81`; Range: min: 81, max: 121)
- `resolution` (string, optional): Resolution of video. 16:9 corresponds to 832x480px, and 9:16 is 480x832px (Default: `480p`; Options: `480p`, `720p`)
- `disable_safety_checker` (boolean, optional): Disable safety checker for generated video. (Default: `False`)
- `lora_scale_transformer` (number, optional): Determines how strongly the transformer LoRA should be applied. (Default: `1`)
- `image` (string, **required**): Input image to generate video from.
- `sample_shift` (number, optional): Sample shift factor (Default: `12`; Range: min: 1, max: 20)
- `go_fast` (boolean, optional): Go fast (Default: `True`)
- `lora_weights_transformer_2` (string, optional): Load LoRA weights for the LOW transformer_2. Supports arbitrary .safetensors URLs from the Internet. Can be different from transformer LoRA. (for example, 'https://huggingface.co/TheRaf7/instagirl-v2/resolve/main/Instagirlv2.0_lownoise.safetensors')
- `prompt` (string, **required**): Prompt for video generation
- `last_image` (string, optional): Optional last image to condition the video generation. If provided, creates smoother transitions between frames.
