generates video content from spoken audio, with different versions available to suit various computer specifications.
1. calling the api
install the client
the client provides a convenient way to interact with the api.
1pip install inferenceshsetup your api key
set INFERENCE_API_KEY as an environment variable. get your key from settings → api keys.
1export INFERENCE_API_KEY="inf_your_key"run and get result
submit a request and wait for the final result. best for batch processing or when you don't need progress updates.
1from inferencesh import inference23client = inference()456result = client.run({7 "app": "infsh/wan-2-2-s2v",8 "input": {}9 })1011print(result["output"])stream live updates
get real-time progress updates as the task runs. ideal for showing progress bars, partial results, or long-running tasks.
1from inferencesh import inference23client = inference()456# stream=True yields updates as they arrive7for update in client.run({8 "app": "infsh/wan-2-2-s2v",9 "input": {}10 }, stream=True):11 if update.get("progress"):12 print(f"progress: {update['progress']}%")13 if update.get("output"):14 print(f"output: {update['output']}")2. authentication
the api uses api keys for authentication. see the authentication docs for detailed setup instructions.
3. files
file inputs are automatically handled by the sdk. you can pass local paths, urls, or base64 data.
automatic upload
the python sdk automatically detects local file paths and uploads them. urls are passed through as-is.
1# local file paths are automatically uploaded2result = client.run({3 "app": "infsh/wan-2-2-s2v",4 "input": {5 "image": "/path/to/local/image.png", # detected & uploaded6 "audio": "https://example.com/audio.mp3", # url passed through7 }8})4. webhooks
get notified when a task completes by providing a webhook url. when the task reaches a terminal state (completed, failed, or cancelled), a POST request is sent to your url with the task result.
1result = client.run({2 "app": "infsh/wan-2-2-s2v",3 "input": {},4 "webhook": "https://your-server.com/webhook"5}, wait=False)webhook payload
your endpoint receives a JSON POST with the task result:
1{2 "id": "task_abc123",3 "status": 9,4 "output": { ... },5 "error": "",6 "session_id": null,7 "created_at": "2024-01-15T10:30:00Z",8 "updated_at": "2024-01-15T10:30:05Z"9}5. schema
input
first frame image for video generation
audio file for speech-to-video generation
text prompt describing the desired video content
resolution preset
number of frames to generate per chunk
frames per second for the output video
random seed for reproducibility
enable first block cache for faster inference
threshold for first block cache (lower = more acceleration, higher = better quality)
