## Short answer

Kling's official API bills units per second of video, sold in prepaid packs from $9.80 (100 units, 30 days) to $7,560 (60,000 units, 180 days). Kling 3.0 at 1080p with audio uses 1.2 units a second, so a 10-second clip costs $1.18 to $1.68 (Kling, 12 Nov 2026). Resellers charge about the same.

Kling sells its API in prepaid units, resellers sell it per second, and the Kling app sells credits. This page puts all three on one scale: the price of one 10-second clip. Every rate was read from the seller's own page on 12 November 2026.

## How much does the Kling API cost?

Kling's official API costs $0.098 to $0.154 per unit, bought in prepaid packs, and each model uses a set number of units per second of video. [Kling's API pricing page](https://kling.ai/dev/pricing) sells two families of packs.

**General packs** cover every model except Kling 4.0 and Kling 4.0 Flash.

| General pack | Price | Units | Price per unit | Validity | Concurrency |
| --- | --- | --- | --- | --- | --- |
| Trial | $9.80 (list $14) | 100 | $0.098 | 30 days | 5 |
| Trial | $98 (list $140) | 1,000 | $0.098 | 30 days | 5 |
| Standard 1 | $700 | 5,000 | $0.14 | 180 days | 20 |
| Standard 2 | $2,100 | 15,000 | $0.14 | 180 days | 20 |
| Standard 3 | $3,780 | 30,000 | $0.126 | 180 days | 20 |
| Standard 4 | $5,670 | 45,000 | $0.126 | 180 days | 20 |
| Standard 5 | $7,560 | 60,000 | $0.126 | 180 days | 20 |

**Flagship packs** are the only way to call Kling 4.0 and Kling 4.0 Flash.

| Flagship pack | Price | Units | Price per unit | Validity | Concurrency |
| --- | --- | --- | --- | --- | --- |
| Trial | $9 (list $10) | 64 | $0.1413 | 30 days | 5 |
| Trial | $90 (list $100) | 637 | $0.1413 | 30 days | 5 |
| Standard 1 | $500 | 3,250 | $0.15386 | 180 days | 20 |
| Standard 2 | $2,000 | 13,135 | $0.15229 | 180 days | 20 |
| Standard 3 | $8,000 | 53,640 | $0.14915 | 180 days | 20 |

Trial discounts apply to the first buy, and each trial pack can be bought at most five times. Units don't roll over and packs can't be extended, so a 180-day pack you don't finish is money lost.

## How many units does each Kling model use?

Kling 3.0 uses 0.6 units a second at 720p without audio and 1.2 units at 1080p with native audio. Kling's page lists every model per second of output:

| Model and setting | 720p | 1080p | 4K |
| --- | --- | --- | --- |
| Kling 3.0, silent | 0.6 | 0.8 | 3.0 |
| Kling 3.0, native audio | 0.9 | 1.2 | 3.0 |
| Kling 3.0 Motion Control | 0.9 | 1.2 | n/a |
| Kling 3.0 Turbo, native audio | 0.8 | 1.0 | n/a |
| Kling 3.0 Omni, no reference video, silent | 0.6 | 0.8 | 3.0 |
| Kling 3.0 Omni, no reference video, audio | 0.8 | 1.0 | 3.0 |
| Kling 3.0 Omni, with reference video, silent | 0.9 | 1.2 | 3.0 |
| Kling 4.0, no input video | 1.0 | 1.5 | n/a |
| Kling 4.0, with input video | 0.6 | 0.9 | n/a |
| Kling 4.0 Flash, no input video | 0.6 | n/a | n/a |
| Kling 4.0 Flash, with input video | 0.4 | n/a | n/a |
| Avatar | 0.4 | 0.8 | n/a |

Kling 4.0 with an input video bills more seconds than it outputs. If the input is no longer than the output, Kling bills twice the output duration. If the input is longer, it bills input plus output seconds. A 10-second Kling 4.0 edit at 1080p from a 10-second input is 20 billed seconds at 0.9 units, or 18 units.

## What does a 10-second Kling clip cost on the API?

A 10-second Kling 3.0 clip at 1080p with native audio costs $1.18 to $1.68 on the official API, depending on the pack. The table multiplies units per second by 10 and by each pack's unit price.

| 10-second clip | Units | Trial ($0.098) | Standard 1-2 ($0.14) | Standard 3-5 ($0.126) |
| --- | --- | --- | --- | --- |
| Kling 3.0, 720p, silent | 6 | $0.59 | $0.84 | $0.76 |
| Kling 3.0, 1080p, silent | 8 | $0.78 | $1.12 | $1.01 |
| Kling 3.0, 720p, audio | 9 | $0.88 | $1.26 | $1.13 |
| Kling 3.0, 1080p, audio | 12 | $1.18 | $1.68 | $1.51 |
| Kling 3.0, 4K | 30 | $2.94 | $4.20 | $3.78 |

| 10-second clip, Flagship | Units | Trial ($0.1413) | Standard 1 ($0.15386) | Standard 3 ($0.14915) |
| --- | --- | --- | --- | --- |
| Kling 4.0, 720p | 10 | $1.41 | $1.54 | $1.49 |
| Kling 4.0, 1080p | 15 | $2.12 | $2.31 | $2.24 |
| Kling 4.0 Flash, 720p | 6 | $0.85 | $0.92 | $0.89 |

A $9.80 General trial pack covers about sixteen 10-second 720p silent Kling 3.0 clips, or eight at 1080p with audio. That is enough to wire up and test an integration before you commit to $700.

## Is Kling's official API cheaper than resellers?

Kling's official API and fal charge the same per second on Kling 3.0, and Runway charges a little more. On Kling 4.0, Runway is cheaper while its launch discount runs.

| 10-second clip | Kling API ($0.14 pack) | fal | Runway API |
| --- | --- | --- | --- |
| Kling 3.0 Standard (720p), silent | $0.84 | $0.84 | $0.90 |
| Kling 3.0 Standard (720p), audio | $1.26 | $1.26 | $1.30 |
| Kling 3.0 Pro (1080p), silent | $1.12 | $1.12 | $1.20 |
| Kling 3.0 Pro (1080p), audio | $1.68 | $1.68 | $1.70 |
| Kling 3.0 4K | $4.20 | not listed | $4.30 |
| Kling 4.0, 1080p, no input video | $2.31 (Flagship $0.15386) | not listed | $1.88 until 30 Nov, then $2.35 |

Sources: [fal Kling 3.0 Standard](https://fal.ai/models/fal-ai/kling-video/v3/standard/text-to-video) and [Pro](https://fal.ai/models/fal-ai/kling-video/v3/pro/text-to-video), [Runway API pricing](https://docs.dev.runwayml.com/guides/pricing/). Kling sorts its API by resolution and fal and Runway sort by Standard and Pro; the table matches Standard to 720p and Pro to 1080p, where the per-second prices match. fal adds voice control at $0.154 (Standard) and $0.196 (Pro) a second.

Choose by what you need beyond price. The official API gives 20 concurrent jobs on 180-day packs and sells Kling 4.0 Flash. fal and Runway bill per second with no prepaid pack, so nothing expires. Runway also sells MiniMax H3 and other video models under the same key.

## Is the Kling API cheaper than a Kling app plan?

No. The Kling app's Ultra plan costs less than half the price per second of the API's 180-day packs, but app credits only pay for clips made in Kling's own app. Kling's two tables line up at 10 app credits per API unit: Kling 3.0 at 1080p with audio is [12 app credits a second](https://kling.ai/quickstart/klingai-video-3-model-user-guide) and 1.2 API units.

| Route | Price of 10 app credits or 1 API unit | 10 s, 1080p, audio |
| --- | --- | --- |
| App Ultra ($159.99 for 26,000 credits) | $0.062 | $0.74 |
| App Pro ($32.56 for 3,000 credits) | $0.109 | $1.30 |
| App Standard ($8.80 for 660 credits) | $0.133 | $1.60 |
| App top-up ($1 for 66 credits) | $0.152 | $1.82 |
| API General trial pack | $0.098 | $1.18 |
| API General 180-day, $0.126 | $0.126 | $1.51 |
| API General 180-day, $0.14 | $0.14 | $1.68 |

App plan prices are renewal prices from [Kling's credit guide](https://kling.ai/blog/kling-video-3-0-credit-cost-guide); the top-up rate is from [Kling's credits policy](https://kling.ai/docs/point-policy). Use the app when a person makes the clips. Use the API when code makes them: in a product, a batch job or an automation. The full plan breakdown is on the [Kling AI pricing page](https://honeyvid.ai/learn/kling-ai-pricing/), and the [credits converter](https://honeyvid.ai/learn/ai-video-credits-converter/) compares credits across apps.

## Which Kling API option should you buy?

Buy the smallest pack that covers 30 days of real use, because units expire.

1. **Testing an integration:** the $9.80 General trial pack, 100 units.
2. **Kling 4.0 tests:** the $9 Flagship trial pack, 64 units, or Runway while its discount lasts.
3. **Steady production on Kling 3.0:** a $3,780 General pack at $0.126 a unit, if you will use 30,000 units in 180 days.
4. **Spiky or low volume:** fal or Runway, billed per second with nothing prepaid.
5. **Motion transfer:** Kling 3.0 Motion Control at 0.9 to 1.2 units a second; see [Kling motion control](https://honeyvid.ai/learn/kling-motion-control/).

## Questions

### How much does the Kling API cost?

Kling's official API sells prepaid units. Trial packs cost $9.80 for 100 units or $98 for 1,000 and last 30 days. 180-day packs run from $700 for 5,000 units to $7,560 for 60,000. Kling 3.0 uses 0.6 to 1.2 units per second at 720p and 1080p.

### How much is the Kling 3.0 API per second?

At 720p silent, Kling 3.0 is 0.6 units a second, or $0.059 to $0.084 depending on the pack. At 1080p with native audio it is 1.2 units, or $0.118 to $0.168. 4K costs 3.0 units a second, $0.29 to $0.42.

### Is there a free Kling API?

No. Kling's developer page lists only paid packs. The cheapest is the $9.80 trial pack with 100 units, enough for about sixteen 10-second 720p silent Kling 3.0 clips, and it expires after 30 days.

### Do Kling app credits work in the API?

Kling sells them separately: the app runs on credits from plans and top-ups, and the API runs on resource units from prepaid packs. Kling's credits policy covers app credits and does not mention the API. The two price tables line up at 10 app credits per API unit for every Kling 3.0 setting.

### Can I use Kling 4.0 with a General pack?

No. Kling's pricing page says General packs are not compatible with Kling 4.0 or Kling 4.0 Flash. Those models need a Flagship pack, which costs $0.1413 to $0.15386 a unit.
