Kling 3.0 4k API
Kling 3.0 4k is a video generation model from Kling, live in the video lane of the Corent catalog. It renders at 720p and 1080p and 4k in 16:9, 1:1, 9:16, served on POST /v1/videos/generate and billed only on success.
Pin it by name, or let the router earn it.
You pick
POST /v1/videos/generate{ "prompt": "a lighthouse at dusk", "model": "corent-kling-3.0-4k"}
Direct access runs Kling 3.0 4k and no other model. No substitution, flat cost-plus, billed only on success, and the receipt names the model you pinned.
The router picks
POST /v1/videos/generate{ "prompt": "a lighthouse at dusk", "tier": "premium"}
Name a tier and the router reads the prompt, scores every live video model on quality and price, and may pick Kling 3.0 4k whenever it wins. Failed attempts cost $0.
One key, one request.
curl -X POST https://api.corent.tech/v1/videos/generate \ -H "Authorization: Bearer $CORENT_API_KEY" \ -H "Content-Type: application/json" \ -d '{"prompt": "a fox reading a book", "model": "corent-kling-3.0-4k"}'
The response carries the result and a receipt: the model that served you and the exact cost in cents. Full request and response shapes are in the docs.

Common questions
Does Kling 3.0 4k have an API?
Yes. Kling 3.0 4k is served through the Corent API on POST /v1/videos/generate. Pin the exact name corent-kling-3.0-4k and you get that model or nothing: no substitution, and a failed generation is never billed. One Corent key covers it alongside every other model in the catalog.
How much does Kling 3.0 4k cost via Corent?
Corent does not publish a per-model rate card. Direct access is flat cost-plus, you are billed only on success, and every response carries the exact charge on its receipt. Tier prices are public on the pricing page at corent.tech/pricing.
Do I have to pick Kling 3.0 4k?
No. Send a tier instead of a model and the router reads each prompt, picks the best live model at that moment, and reroutes on failure. Pinning corent-kling-3.0-4k is for when you want exactly this model on every request.
