Kling 3.0 video API pricing: Standard, Pro, audio, and 4K compared
Kling 3.0 does not have one API price. Standard, Pro, 4K, native audio, voice control, resolution, and promotional rates can all change the bill. This comparison keeps those configurations visible and places Cheap.dev’s live rates beside like-for-like public routes.
Kling 3.0 video API price table
Prices are normalized to one generated second and a five-second clip. Promotional rates and configurations that do not state tier or audio mode are labeled rather than treated as direct equivalents.

| WaveSpeedAI | Kling 3.0 Standard headline rate; parameters may change price | $0.084 | $0.42 |
| Atlas Cloud | Kling V3 Turbo image/text-to-video; 15% promotional starting rate | from $0.095 | from $0.48 |
| Cheap.devOurs | Standard, no sound | $0.07 | $0.35 |

Every numeric price links to the provider-owned pricing page that publishes it. Prices exclude taxes and enterprise discounts. Standard, Turbo, Pro, and O3 4K are distinct variants and are labeled rather than treated as direct equivalents.

What Kling’s official billing table tells us
Kuaishou’s official Kling 3.0 guide uses an internal billing unit rather than public API dollars. Its relative rates increase with resolution, native audio, and voice control. That structure explains why provider pages must state both resolution and audio mode, even when their API marketplace uses different tier names.
Why Kling 3.0 prices look inconsistent
Audio adds roughly 56–57% on Cheap.dev Standard and Pro routes
Cheap.dev’s price rises from $0.07 to $0.11/sec for Standard and $0.09 to $0.14/sec for Pro when sound is enabled. External headline prices in this audit do not all state an equivalent audio setting.
Voice control is another billing mode
Cheap.dev’s current public catalog exposes sound rates but does not list a separate voice-control feature, so this article does not invent or infer a voice-control dollar price.
4K and O3 are separate cost tiers
Atlas Cloud’s verified 4K figure is for Kling O3, not Kling V3 Standard. It appears as a market reference with the O3 label, not as a like-for-like Standard comparison.
Which Kling 3.0 API should you choose?
- Lowest published Standard headline: Cheap.dev publishes $0.07/sec for Standard without sound, below WaveSpeedAI’s $0.084/sec headline.
- Turbo and O3 4K options: Atlas Cloud publishes promotional starting rates for both variants.
- Published Cheap.dev configurations: Direct USD rates range from $0.07/sec for Standard without sound to $0.35/sec for 4K.
- Agent-first multi-model workflow: Cheap.dev combines model discovery, browser testing, saved tokens, OpenAPI resources, and an installable agent skill behind one API surface.
