Kling API FAQ
- How much does the Kling API cost?
- On Unifically, Kling video starts at $0.03 per second of output (Kling 2.6 and 2.5 Turbo Standard) and tops out at $0.30 per second for 4K on the 3.0 line. Kling image generation is $0.01–$0.04 per image. Billing is per generation with no subscription or monthly minimum; live rates are on the pricing page.
- Is there an official Kling API?
- Kuaishou offers an official Kling developer platform. Unifically provides the same Kling models through one REST API alongside 60+ other video, image, and audio models — one balance, one API key, per-second billing, and a browser playground on every model page.
- Which Kling model should I use?
- Kling 3.0 is the current flagship for quality and native audio. Kling 2.6 or 2.5 Turbo are the cheapest at $0.03/sec for drafts and volume work. The O1 and Omni Edit routes edit existing footage instead of generating from scratch, and Motion Control transfers movement from a driving video onto a still subject.
- Do I need a Kling subscription to use the API?
- No. Unifically is pay-per-use: you top up a balance and each generation deducts its exact cost. There is no monthly fee, seat license, or credit expiry.
