Output is always silent; `audio` and `audio_url` are rejected. `resolution` is `720p` (default) or `1080p`, and `duration` is 2–15 seconds (default 5). ```bash theme={null} curl --fail-with-body --silent --show-error \ -X POST https://api.wizzx.ai/api/v1/task/submit/wan-2.6-flash \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ --data '{ "prompt": "The person smiles and waves while the camera slowly zooms in", "image_urls": ["https://example.com/portrait.jpg"], "resolution": "720p", "duration": 5 }' ``` The gateway charges per second: 720p = 33, 1080p = 54 credits. Read `/pricing` for the current amount. ## OpenAPI ````yaml POST /api/v1/task/submit/wan-2.6-flash openapi: 3.0.3 info: title: Wizzx AI API version: 1.2.0 description: >- Wizzx asynchronous image, video, and audio generation API.
