# Kling 3.0 Turbo video

Animate a still image into a video using Kling 3.0 Turbo, at 720p. You supply one image and a prompt describing how it should move. The image can be a file you upload out of band and reference by handle, a public link, or the file's own bytes sent inline, so a local or private image never has to be published anywhere. Returns the URL of the generated MP4. That URL is temporary: kie.ai deletes generated media after 14 days and Goro holds a run's results for 24 hours, so collect what you need within 24 hours.
Use when you already have the frame you want and need it to move: a product shot that pans, a generated image brought to life, a character that speaks. Pairs directly with the image endpoints. The most expensive per second of the image-to-video models here, so reach for video.grok or video.seedance first unless you specifically want Kling's motion. To send a local or private image, upload it first (POST /v1/uploads, or create\_upload over MCP, or goro run --image) and pass the handle as image\_handle, so the file never travels through the request. Billed per second of video you ask for.
## Price
**\$0.27 per second of video.** An exact rate, not an estimate. The total is that rate times the seconds of video in your request, so you can work out what a call costs before you make it.
No call costs less than $0.0020 or more than $4.05, the price of the largest request this endpoint takes, 15 seconds of video. `discover` and `inspect` quote your exact request before it runs.
## Input
| Field | Type | Required | Notes |
| -------------- | --------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `prompt` | `string` | yes | How the image should move. Describe the action, the camera move and any dialogue; Kling generates matching audio. |
| `duration` | `integer` | | Length of the generated video in seconds. This is what you are billed on, and it is the only field that changes the price. Defaults to `5`. |
| `image_urls` | `array` | | One public http or https link to the starting image (JPEG or PNG, up to 10 MB). Use this when the image is ALREADY published somewhere; the output URL of an image endpoint works directly. For a file that is not already public, send image\_handle instead and it never has to be published anywhere. Exactly one of image\_handle, image\_urls and image\_base64 is required. |
| `resolution` | `720p` | | Fixed at 720p. Resolution changes the price per second, and this endpoint quotes one exact rate, so 1080p would get its own endpoint. Defaults to `"720p"`. |
| `image_base64` | `string` | | Only for a SMALL image (under 3 MB) or a caller that cannot run a shell command. The image inline, as base64 of the file's own bytes; a data:image/png;base64, prefix is accepted and its declared type ignored. Understand the cost before choosing it: this string is part of the request, and on an MCP call the request IS the tool arguments, which pass through the model's context window. A 3 MB photograph is 4 MB of base64, on the order of a million tokens, and in practice it is truncated and the run fails looking like file corruption. Do not downscale an image to fit here: use image\_handle, which takes up to 10 MB and keeps the file out of the conversation entirely. Kling accepts JPEG and PNG. Exactly one of image\_handle, image\_urls and image\_base64 is required. |
| `image_handle` | `string` | | The RIGHT WAY to send a local or private image. Upload the file first with POST /v1/uploads (or the create\_upload MCP tool, or the CLI's --image flag, which does the whole thing for you) and put the short handle it returns here. The file goes straight from you to a private bucket: it never passes through a tool call, so it never passes through a model's context window, and up to 10 MB is fine. Nothing is published. The handle is usable for 10 minutes after the upload lands and the file is deleted 30 minutes after that. Kling accepts JPEG and PNG. Exactly one of image\_handle, image\_urls and image\_base64 is required. |
These are all the fields this endpoint accepts. Anything else is rejected as
a `validation_error` rather than forwarded to the provider.
