Video generation

Video generation is asynchronous: you submit a job, then poll for the result.

Submit a job

curl https://api.heyaskr.ai/v1/videos \
  -H "Authorization: Bearer ASKR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kling-2.0",
    "prompt": "a paper boat sailing down a rain gutter, slow motion",
    "aspect_ratio": "16:9",
    "duration": "5"
  }'

The response returns a job id, an estimated_cost, and status: "pending".

Poll for the result

curl https://api.heyaskr.ai/v1/videos/JOB_ID \
  -H "Authorization: Bearer ASKR_API_KEY"

Poll every 5–10 seconds until status is completed (the response includes the video URL) or failed.

You are only charged when a job completes successfully. Failed jobs are not billed.
