How much does the Kling API cost?

Kling 3.0 costs $0.084 to $0.42 per second on the official API, depending on resolution and audio [1]. Kling API pricing is listed per second of generated video, so you multiply the rate by clip length.

Without audio, the official Kling 3.0 rates are $0.084 per second at 720p, $0.112 at 1080p and $0.42 at 4K [1]. With native audio (no voice control) they are $0.126 at 720p, $0.168 at 1080p and $0.42 at 4K [1].

Older and Turbo models cost less. Kling 3.0 Turbo with native audio is $0.112 per second at 720p and $0.14 at 1080p [1]. Kling 2.6 without audio is $0.042 at 720p and $0.07 at 1080p [1].

• A 10-second 720p clip without audio costs $0.84 at $0.084 per second [1].
• A 10-second 1080p clip with audio costs $1.68 at $0.168 per second [1].

What is the Kling API and how is it billed?

The Kling API is Kling AI's official programmatic access to its video models, billed per second of video in Units [1]. The official price list shows a dollar amount next to the Units for each model and resolution.

Resellers offer the same Kling models through their own APIs and set their own prices. Kie.ai bills in credits at $0.005 per credit [5]. fal.ai, Replicate, WaveSpeed and PiAPI list dollars per second, and Runway sells Kling 3.0 through the Runway API [2][6][7][10][11].

Because each seller prices on its own page, rates for the same model can differ. Resellers' prices can change, and the final charge is what the platform bills. For the app plans, see Kling AI pricing.

Kling 3.0 API price per second by seller

List prices from each seller's own pricing page, accessed 2026-10-18. Official first, then Kie.ai, Higgsfield, fal.ai, WaveSpeed, PiAPI, Replicate and Runway. Higgsfield rates are its labelled 50%-off prices. Every seller except Kling official is an independent third-party reseller, not Kling and not endorsed by Kling. fal.ai and WaveSpeed list Standard and Pro tiers rather than resolutions.

Prices as of the date shown; confirm on the provider's site.

How much does fal.ai charge for Kling?

fal.ai charges the same per-second rates as the official Kling API for Kling 3.0: $0.084 (Standard) and $0.112 (Pro) with audio off [2][3]. fal.ai lists Standard and Pro tiers and doesn't state their resolution; the rates match Kling's official 720p and 1080p prices [2][3][1]. It is a reseller, so it is not cheaper than Kling's own API on these models.

With audio on, Standard is $0.126 and Pro is $0.168 per second [2][3]. Voice control adds more: $0.154 per second on Standard and $0.196 on Pro [2][3]. Kling 2.6 Pro on fal.ai is $0.07 per second with audio off and $0.14 with audio on [4].

A 10-second Kling 3.0 Pro clip with audio costs $1.68 at $0.168 per second [3].

Choose this if you already use fal.ai and want official-level rates on one bill. Skip it if you want a lower per-second rate than the official API.

What is Kie.ai pricing for Kling?

Kie.ai bills in credits at $0.005 per credit, and its Kling 3.0 rates sit below the official API [5]. Without audio it is $0.07 per second at 720p (14 credits) and $0.09 at 1080p (18 credits) [5].

With audio, Kling 3.0 is $0.10 per second at 720p (20 credits) and $0.135 at 1080p (27 credits) [5]. 4K is $0.335 per second (67 credits) [5]. A 10-second 1080p clip with audio costs $1.35 at $0.135 per second [5].

Kie.ai also lists Kling 3.0 Turbo at $0.09 per second (720p) and $0.1125 (1080p), with audio not stated on the page [5]. Kling 2.5 Turbo Pro, which Kie.ai says generates 1080p, is $0.21 per 5-second clip and $0.42 per 10-second clip [5][12]. That works out to $0.042 per second, against Kling's official 1080p rate of $0.07 [5][1].

Choose this if you are fine with credit billing and a third-party reseller. Skip it if you need Kling's own support, or audio details for Kling 3.0 Turbo, which Kie.ai doesn't state [5].

What is Replicate's Kling pricing?

Replicate charges $0.168 per second for Kling 3.0 standard (720p) and $0.224 for pro (1080p), both without audio [6]. With audio the rates are $0.252 and $0.336 per second [6]. 4K is $0.42 per second [6].

Those rates are about double the official API at 720p and 1080p. A 10-second 1080p clip with audio costs $3.36 on kwaivgi/kling-v3-video, against $1.68 officially [6][1]. At 4K the price equals the official $0.42 per second [6][1].

Choose this if you build on Replicate already and the clips are short or few. Skip it if you generate at 720p or 1080p in volume.

What is WaveSpeed's Kling pricing?

WaveSpeed lists Kling 3.0 Standard at $0.084 per second and $0.126 with sound, matching the official 720p rates, though WaveSpeed doesn't state the resolution [7][1]. Kling 3.0 Pro is $0.112 per second and $0.168 with sound [8].

Its pricing page says eligible new accounts get $1 in free credits [9]. It also notes: "Starting prices are list prices at the lowest resolution or quality. Actual cost depends on resolution, duration and other parameters, and discounts may apply." [9]

Choose this if you want official-level rates. WaveSpeed says eligible new accounts get $1 in free credits [9]. Skip it if you want a rate below the official API.

What is PiAPI's Kling pricing?

PiAPI charges $0.10 per second for Kling 3.0 at 720p and $0.15 at 1080p without audio [10]. With audio the rates are $0.15 and $0.20 per second [10].

Kling 3.0 Turbo without audio is $0.13 per second at 720p and $0.19 at 1080p [10]. A 10-second 1080p clip with audio costs $2.00 on PiAPI, $0.32 more than the official $1.68 [10][1].

Choose this if PiAPI already fits your stack and the price gap is acceptable. Skip it if cost per clip is your main filter.

What is Higgsfield's Kling API pricing?

Higgsfield sells Kling through its own API and labels every Kling rate 50% off its list price as of 2026-10-18 [13]. Its list prices match Kling's official rates, so the discounted rates are half the official price [13][1].

Kling 3.0 Standard text-to-video is $0.042 per second (list $0.084), and Kling 3.0 Pro is $0.084 per second for 3 to 15 second clips (list $0.168) [14][15]. Its Pro page also shows $0.056 per second for 1-second clips, which this model doesn't offer [15]. Kling 3.0 Turbo is $0.07 per second at 1080p; the page's $0.056 rate at 720p is attributed to 1-second clips, though Turbo takes 3 to 15 seconds [16]. 4K is $0.21 per second [17]. Kling 2.5 Turbo Pro is $0.035 per second at 1080p [18].

Higgsfield doesn't say when the 50% discount ends, and its Kling 3.0 Pro page doesn't label resolution or sound [13][15]. A 10-second Kling 3.0 Pro clip costs $0.84 at $0.084 per second [15].

Choose this if you are fine with a third-party reseller and a promotional rate that can change. Skip it if you need a rate that won't change when a discount ends, or clear audio pricing per mode.

What is the cheapest Kling API?

Higgsfield lists the lowest Kling 3.0 rates as of 2026-10-18, but as a 50% discount on its list price [13]. Its Kling 3.0 Pro rate of $0.084 per second is below every other seller's 1080p with-audio rate, though Higgsfield doesn't label resolution or sound [15]. Without a discount label, Kie.ai is lowest at $0.135 per second for 1080p with audio, $0.033 below the official $0.168 [5][1].

Here is the ranking for Kling 3.0 at 1080p with audio, cheapest first: Higgsfield $0.084 on its discounted Pro tier (resolution and sound not labelled) [15]; Kie.ai $0.135 [5]; Kling official $0.168, and fal.ai and WaveSpeed $0.168 on their Pro tier (resolution not stated) [1][3][8]; Runway $0.17 on its Pro tier (resolution not stated) [11]; PiAPI $0.20 [10]; Replicate $0.336 [6].

At 720p without audio, a 10-second clip costs $0.70 on Kie.ai, $0.84 on the official API, $1.00 on PiAPI and $1.68 on Replicate [5][1][10][6]. For every model in one view, use the live cost-per-second table. The method behind our figures is on the methodology section.

Conclusion

Kling 3.0 starts at $0.084 per second at 720p on the official API and reaches $0.168 at 1080p with audio [1]. Higgsfield lists half the official rate while its discount applies (its Pro tier doesn't label resolution or sound), Kie.ai is lower at $0.135, fal.ai and WaveSpeed match the official rate, and PiAPI, Runway and Replicate cost more [13][5][3][8][10][11][6].

If price per second is your main filter, Higgsfield lists the lowest Kling 3.0 rates as of 2026-10-18 while its 50% discount applies, and Kie.ai lists the lowest rate without a discount label [13][5]. The official API, fal.ai and WaveSpeed charge the official rate, and Replicate or PiAPI fit best if your stack already depends on them. Rates can change, so confirm on each seller's page.

Next steps:

1. Multiply your clip length by the rate for your resolution and audio setting, for example 10 s × $0.168 = $1.68 [1].
2. Compare your model and resolution in the live cost-per-second table.
3. Read Kling AI pricing for app plans alongside API rates.
4. Confirm the final rate on the seller's own page before you buy, then send a price correction if a figure here is out of date.
