Which Kling version should I use?
Integrate the Kling API
Create a server-side API key, submit the supported inputs for your chosen model, and keep the returned task ID to retrieve the result. Model pages link to the exact request contract.
- 1
Create an API key
Sign in and create a key in the dashboard. Set WIZZX_API_KEY in your server environment; never expose it in browser code.
- 2
Submit a task
Send a POST request to the model endpoint. A successful submission returns data.task_id; keep that ID before polling. Submission is not generation completion.
- 3
Retrieve the result
Replace YOUR_TASK_ID with the returned ID and query /api/v1/task/status. Wait for SUCCEEDED and read the output URLs. Stop on FAILED or REVIEW_REQUIRED; do not automatically resubmit an uncertain task.

- Is this the official Kling API?
- No. Kling models are developed by Kuaishou. Wizzx is an independent API platform that gives you access to them with one API key, an asynchronous task API and pay-as-you-go credits.
- What are the Kling API model IDs?
- Submit tasks to POST /api/v1/task/submit/{model_id} with one of: kling-ai, kling-v3, kling-v3-omni.
- Am I charged if a task fails?
- No. Credits are reserved when you submit a task and refunded if it fails. You are only charged for successful tasks.
- Can I try the Kling API for free?
- Yes. New accounts start with $0.20 in free credits, about 5 seconds of video with Kling AI, the lowest-priced version.
