Why teams call Kling Motion Control (kling-v2-6-motion-control) through APIMart

• One key, entire catalog. The same https://api.apimart.ai/v1 base URL and Authorization header reach Kling Motion Control (kling-v2-6-motion-control) and 300+ other image, video and language models — switch the model field, not your client.
• Per-second billing. A job is charged for the seconds it actually generates at the resolution you picked.
• The charge comes back in the response. Every completed task reports the amount billed (cost / credits_cost); a task marked failed is refunded.
• Async by design. Submit, take the task_id, poll GET /v1/tasks/{id} — batching and retries are ordinary queue work, not a bespoke integration.

Kling Motion Control transfers motion from a reference video to your image with Kling V2.6 or V3.

Endpoint: POST https://api.apimart.ai/v1/videos/generations (OpenAI-compatible), then poll GET /v1/tasks/{task_id}.

Prices are a snapshot; the pricing page and data/model.json are refreshed by CI, and a completed task reports the exact amount in its cost field.

The table lists the fields accepted by the APIMart OpenAI-compatible video endpoint. Check the model page for anything this model adds on top.
