What Is the Cheapest AI Video API for Seedance, Kling and Wan?

What is the cheapest AI video API for each model and resolution?

Makernice has the lowest listed per-second price on 2 of the 30 AI video model and resolution pairs below, and is above the lowest listed price on 28. Makernice is lowest on MiniMax H3 Max 768p, MiniMax H3 Max 1080p.

Lowest listed per-second price by AI video model and resolution, checked November 11, 2026. Platform columns use a platform's text-to-video price when it lists modes separately, the same rule as the model pages. Model pages show up to 10 platforms per model and always keep the platform with the lowest published price at each resolution.

How much does AI video cost per second and per video through an API?

An AI video API run costs the per-second price times the clip length, at the model and resolution you choose. A 10-second Seedance 2.5 clip at 720p on Makernice costs 10 × $0.2592/s = $2.59 (price list v15).

Makernice video prices on price list v15 run from $0.03/s (MiniMax H3 Max Turbo, 480p) to $1.955/s (Seedance 2.5, 4K). Every model and resolution is on the Makernice pricing page, and the AI video cost calculator multiplies the same prices for a batch of clips.

The same math works for the other platforms in the table above. A platform that lists a price per clip is shown per second, as the clip price divided by the clip length.

What is the cheapest way to use an AI video API across providers?

Comparing AI video API providers only works for the same model at the same resolution, because each resolution is a separate price on every platform. The gap can be large: for MiniMax H3 at 768p, listed prices run from $0.0155/s on yir.ai to $0.1/s on Flaq AI, MuAPI and WaveSpeedAI, more than 6 times the lowest (checked November 11, 2026).

1. Fix the model and resolution. A Seedance 2.5 price at 720p says nothing about its 1080p price.
2. Compare listed USD per-second prices. Use the price on each platform's own pricing page, with the date you checked it.
3. Add the billing terms. Check the minimum purchase, whether failed runs are charged, whether credits expire and how long output files are kept.
4. Multiply by the seconds you will generate. The total for your clip lengths is the number to compare.

Are unlimited AI video plans really unlimited?

Makernice has no unlimited plan and no subscription: every AI video run is billed per second of output from a prepaid USD balance, and the price is shown before the run starts.

Plans named Unlimited appear on 3 of the pricing pages Makernice tracks: CDance AI (Unlimited Monthly, Unlimited Yearly; checked November 11, 2026); China Video AI (Unlimited Monthly, Unlimited Yearly; checked November 11, 2026); RSW AI Studio (Plus Unlimited, Pro Unlimited, Pro Ultra Unlimited, Pro Max Unlimited; checked November 11, 2026). Plans like these are not per-second USD prices, so they are not in the table above.

• Higgsfield's pricing terms say: "Unlimited usage may be subject to dynamic speed adjustments during high-traffic periods." (checked November 11, 2026)
• OpenArt's pricing terms say: "we may temporarily place high-activity accounts in a slower queue, but you can still enjoy unlimited generation." (checked November 11, 2026)

To compare a monthly AI video plan with per-second billing, divide the plan's monthly price by the seconds of video you actually generate in a month at one model and resolution, then compare that figure with a per-second price for the same model and resolution.

Why does the same AI video model cost different amounts on different platforms?

Platforms that host the same AI video model each set their own per-second price and billing terms, so the listed price is only part of what a run costs.

• Credits. 16 tracked platforms price at least one of these AI video models in credits, and one credit is worth a different amount on each plan or pack. Makernice bills in US dollars.
• Promotions. 2 tracked platforms show a promotional per-second price for at least one of these models; promotions end, so they are left out of the table.
• Minimum purchase. Makernice top-ups start at $15 and go up to $1,000; other platforms set their own minimums.
• Failed runs. Makernice does not charge failed runs, timeouts or input-moderation rejections; the hold is released. If a finished output is blocked by output moderation, the run is still charged, and you can contact support for a manual review.
• Expiry and files. The Makernice prepaid balance never expires. Each output carries an expiry time (expiresAt); in the docs example it is 30 days after the run finishes.

Each tracked platform's billing unit, failed-run rule, credit expiry and minimum purchase are listed with check dates on its page under API alternatives.

What does Makernice offer for AI video besides the per-second price?

Makernice shows the exact price before every AI video run, bills it from a prepaid USD balance that never expires, and has no subscription.

• Quote first. POST /v1/generations/quote returns the price, and the quote is locked for 12 minutes; the generation is then created with that quote id. In MCP clients, estimate_cost returns a price without creating a job or charging your balance.
• Failed runs. Failed runs, timeouts and input-moderation rejections are not charged. If a finished output is blocked by output moderation, the run is still charged; you can contact support for a manual review.
• No subscription. Makernice is prepaid in US dollars, the balance never expires, and there are no free credits.
• One API key. One Makernice API key calls all 19 video and image models, over the REST API or the MCP server.
• Limits. Makernice has no batch endpoint, and an account runs 2 generations at once by default.
