AI video API price per second, model by model
AI video API price per second for every model on one key: credits and dollars per second at the lowest and highest resolution, and what sound adds.
On Kinoseed, the AI video API price per second runs from 6.7 credits ($0.13) on MiniMax Hailuo 2.3 Fast to 290 credits ($5.80) on Seedance 2.0 at 4k, as of 15 Nov 2026. Every model is behind one key and one prepaid balance, the price of any request can be checked without charge with POST /api/v1/quote, and a failed run is refunded.
Generating begins with a plan from $10 a month (500 credits a month). Every tool page is open to browse without an account. The table below gives each model's rate at its lowest and its highest resolution; the sections after it explain what moves the number and how to get the exact price of a request before you send it.

Price per second by model
Credits and dollars per second of output, read from a 5 second clip (or the model's only length), without added sound. Dollars are at the headline credit price; plans with more credits pay less per credit.

Computed from the quote the API charges with, as of 15 Nov 2026. A model that only animates images is priced from a start frame.
What moves the price per second
Three things: the model, the resolution and sound. The provider bills per second of output, so a 10 second clip costs about twice a 5 second one on the same settings, and the rate per second stays put. Resolution is the bigger lever: the same model can cost several times more per second at its top resolution than at its lowest.
That is why one headline number for a video API misleads. A light model at its lowest resolution and a flagship model at 1080p are many times apart for the same few seconds, and the table shows by how much. Compare the rate at the resolution you will actually ship.
What sound adds
On Seedance 2.0, Grok Imagine (per fal's model page as of 13 Nov 2026), Seedance 2.5, Seedance 2.0 Mini, Seedance 2.0 Fast, sound is generated with the picture and is part of the rate in the table, so there is nothing to add.
On Kling 3.0, Kling 3.0 Standard, Kling 2.6 Pro, sound is a switch (audio: true) that raises the price: a 5 second Kling 3.0 clip is 110 credits silent and 160 with sound. It is off by default, so a request never pays for sound it did not ask for.
The exact price of one request
The table is a guide; the quote is the contract. Send the body you are about to run to POST /api/v1/quote and it returns the credits that request will cost, after the duration and resolution are snapped to what the model allows. It charges nothing and needs only a key. The Quote page shows the request and the response.
GET /api/v1/models also prices one example run per model, so an agent can compare models before it picks one, and the MCP server exposes the same quote tool. An agent should quote, tell you the number, and only then call generate_video.
From credits to dollars
Every price is in credits, and credits come from a plan. The dollar figures here use the headline credit price, which is what the smallest plan pays; larger plans pay less per credit, so the same clip costs less in dollars on them. Unused credits roll over from month to month.
The text to video API pricing guide prices every text model at its shortest and longest clip, and the video generation API comparison puts each model next to the provider's own list price, so you can see what Kinoseed adds and decide whether the quote, refunds and MCP server are worth it to you.
Picking a model by price
Draft on the cheapest rate that shows the idea, then run the keeper on the model you want at the resolution you will ship. MiniMax Hailuo 2.3 Fast is the cheapest per second here; for a clip that needs sound in the same pass, pick one of the models that include it.
Per-model guides go deeper on the models people ask about most: the Seedance 2.5 API, the Grok Imagine video API and the MiniMax H3 API, each with every length and resolution priced and the request to send.
Questions
What is the cheapest AI video API per second on Kinoseed?
MiniMax Hailuo 2.3 Fast: 6.7 credits ($0.13) per second, 40 credits ($0.80) for a 6 second clip.
Is the price per second the same for every length?
Close to it. The provider bills per second of output, so the rate per second holds across lengths on the same model and resolution; rounding to whole credits can move a short clip by a credit.
Do I pay for a run that fails?
No. A failed run is refunded automatically, and the job says so.
Is there a separate API plan?
No. Generating begins with a plan from $10 a month (500 credits a month). Every tool page is open to browse without an account. The same credits pay for the web app, the REST API and the MCP server.
