Integrate this model with one task-based API flow

Kling Video 3.0 is Kuaishou's flagship video model from the Kling 3.0 family, launched globally February 5, 2026 - the model Kuaishou says turns anyone into a director. The examples below are rendered from Kling V3 0, the current gateway base URL, and the selected public model contract using the active example "$41".

Input mode
X-API-Key on every request
POST /api/v1/openapi/task
GET /api/v1/openapi/task/status/{task_id}
Async task workflow

Single code window

Switch language once. Each example already includes both the task creation request and the task status polling request.

Unified Example
API_KEY="<API_KEY>"
BASE_URL="https://api.musespark.ai"
REQUEST_BODY='{
  "model_id": "kling-v3.0",
  "parameters": {
    "prompt": "$41",
    "resolution": "720P",
    "duration": 5,
    "aspect_ratio": "16:9",
    "multi_shot": false,
    "batch_size": 1
  }
}'

CREATE_RESPONSE=$(curl --request POST "$BASE_URL/api/v1/openapi/task" \
  --header "X-API-Key: $API_KEY" \
  --header "Content-Type: application/json" \
  --data-raw "$REQUEST_BODY")

curl "$BASE_URL/api/v1/openapi/task/status/$TASK_ID" \
  --header "X-API-Key: $API_KEY"

Request and response JSON become the documentation

Keep the payload and task status envelope as the primary contract. Field descriptions, optionality, and enum hints now live inline as JSON comments.
