How to use the Kling Omni O3 API

Four steps from signup to a finished generation. Full Python, Node.js, and cURL examples are in the API section below.

1. 1

   Get an API key

   Sign up for a WaveSpeedAI account and copy your API key from the dashboard. New accounts come with free starter credits — enough to run the playground a few dozen times before billing kicks in.

2. 2

   Submit a prediction

   POST your input as JSON to https://api.wavespeed.ai/api/v3/kwaivgi/kling-video-o3-std/text-to-video. The endpoint returns a prediction id immediately — generations are async so you don't hold an open connection during inference.

3. 3

   Poll for completion

   GET https://api.wavespeed.ai/api/v3/predictions/{request_id}/result every 1-2 seconds. The response includes a status field; keep polling until it flips from"queued" or"processing" to"completed".

4. 4

   Read the output URL

   Once status is"completed", read the URL from data.outputs[0]. The URL points to your generated media on the WaveSpeedAI CDN — image, video, audio, or 3D file depending on the Kling Omni O3 variant you called.

Kling Omni O3 API pricing

Pricing is per-output. The final charge scales with the parameters you set in each variant's playground (resolution, duration, output count, references).

Call the Kling Omni O3 API

Sign up for an API key at wavespeed.ai/accesskey, then submit a prediction via REST. The playground generates ready-to-paste samples for any combination of inputs.

# 1. Submit a prediction
curl -X POST "https://api.wavespeed.ai/api/v3/kwaivgi/kling-video-o3-std/text-to-video" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{}'

# 2. Poll the result until status = "completed"
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# Read the output URL from data.outputs[0].

// npm install wavespeed
const WaveSpeed = require('wavespeed');
const client = new WaveSpeed(); // reads WAVESPEED_API_KEY

const result = await client.run("kwaivgi/kling-video-o3-std/text-to-video", {});
console.log(result.outputs[0]); // → URL of the generated output

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "kwaivgi/kling-video-o3-std/text-to-video",
    {}
)
print(output["outputs"][0])  # → URL of the generated output
