}Kling 3.0
Kling 3.0. Highest quality with the full feature set: text-to-video, image-to-video, first & last frame, native audio and multi-shot.
Pricing — per second of generated video, in tokens (USD at $0.02/token):
| resolution | sound off | sound on |
|---|---|---|
| 720p | 4.2 ($0.084) | 6.3 ($0.126) |
| 1080p | 5.6 ($0.112) | 8.4 ($0.168) |
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.
Now served by Kling’s current API. Two changes came with that move: 4K is available (the previous integration could only reach std/pro, i.e. 720p/1080p), and negative_prompt has been removed — the current API has no such field, so put negative descriptions in prompt.
⚠️ At 4K, sound on and sound off cost the same (21 tokens/s = $0.42). That is the official rate.

Optional. A publicly accessible HTTPS URL. When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt.
