Run it

Quote the input, start the generation with the quote, then poll the job. Set RAYWAKE_API_KEY first; see Authentication.

# 1. Price the exact input (quotes are valid for up to 10 minutes)
curl -s https://api.raywake.com/v1/quotes \
  -H "Authorization: Bearer $RAYWAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "minimax/h3/image-to-video",
  "input": {
    "prompt": "A red ceramic cup on a wooden table, soft morning light"
  }
}'

# 2. Start the generation with the quote_id from step 1
curl -s https://api.raywake.com/v1/generate \
  -H "Authorization: Bearer $RAYWAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"model": "minimax/h3/image-to-video", "quote_id": "QUOTE_ID", "input": {"prompt":"A red ceramic cup on a wooden table, soft morning light"}}'

# 3. Poll until the status is terminal
curl -s https://api.raywake.com/v1/jobs/JOB_ID \

Input

Input fields for minimax/h3/image-to-video
Name	Type	Description
`prompt`required	string	Text prompt for video generation
`duration`	number (enum)	The duration of the video in seconds. Default: `5` One of: `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15`
`resolution`	string (enum)	The resolution of the generated video. 480P and 768P are native generation modes; 2K and 4K upscale a 768P base result. Default: `2K` One of: `480P`, `768P`, `2K`, `4K`
`seed`	integer	Random seed. A random seed is selected when omitted.
`sync_mode`	boolean	Return the generated video as base64 instead of a CDN URL. Default: `false`
`prompt_expansion_mode`	string	How much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'fast' returns in about a second. 'balanced' picks per request. 'quality' spends up to ~30s on a richer prompt. Default: `balanced`
`target_audio_url`	string (URL)	Optional URL of an audio clip at least 2 seconds long (maximum 15 MB) to pin to the generated soundtrack. Longer clips are trimmed to the generated video's length, keeping the beginning. The original audio replaces the output soundtrack, padded with silence if shorter than the video, without changing playback speed. Exceptionally high sample rates may be resampled to 96 kHz. Accepts an HTTP(S) URL or a base64 data URI.
`image_url`	string (image URL)	Optional URL of the image to use as the first frame. When provided, the output canvas follows this image. If only end_image_url is provided, the canvas follows that last frame instead. If both images are omitted, the request is handled as text-to-video (16:9 by default).
`end_image_url`	string (image URL)	Optional URL of the image to use as the last frame. It may be provided alone for end-only keyframe generation; in that case the output canvas follows this image.
