# Kling 3

POST https://api.beatapi.io/v1/videos/tasks
Content-Type: application/json

Generate 3–15 second videos at the std or pro tier from text or one or two frames, with multi-shot storyboards and reusable elements; billed per second.- Asynchronous: the create call returns a task ID; the video arrives when the task succeeds.
- Three ways in: text only, a first frame, or a first and last frame. This model takes no reference images, videos or audio.
- `resolution` is a tier: `std` renders at 720p and `pro` (the default) at 1080p.
- Multi-shot: up to five shots, each with its own prompt and length, from one first-frame image. The shot lengths must add up to `duration`.
- Elements: up to three named subjects you define once with `elements`.
- Billed per second of video at the tier you choose. A failed task costs nothing.POST/v1/videos/tasksTry itOpens this model in the API Explorer. Enter your BeatAPI API key to create a task: the call is real and is billed to your own balance.## Endpoint and authentication`POST https://api.beatapi.io/v1/videos/tasks`Authorization
string
RequiredYour BeatAPI API key, sent as `Bearer <BEATAPI_API_KEY>`. Create keys in the [Dashboard](https://beatapi.io/dashboard). Keep keys on your server; never ship them in a browser or mobile app.Send the body as JSON with `Content-Type: application/json`. `Idempotency-Key` is optional: send a unique value (at most 255 characters) per logical request and reuse it only to retry that exact body. Within 24 hours a retry with the same key and body returns the first response again with `Idempotent-Replayed: true`; the same key with a different body returns `409 idempotency_conflict`. Responses other than 2xx are not stored, so a retry after a 400 or 402 runs again.## How a request works`POST` the parameters below to the endpoint. A `201` means the task was accepted and its price reserved from your balance; the work runs in the background. Save `data.id`.Call `GET /v1/tasks/{task_id}` and wait `data.poll_after_seconds` between calls (5 s for images, 8 s for videos) until `status` is `succeeded` or `failed`. Or register a [webhook](/webhooks) for `task.succeeded` and `task.failed`; keep polling as the fallback, because a task stopped by the processing timeout sends no event.On `succeeded`, download every `data.output.media[].url` and store the files you need; BeatAPI does not promise how long result URLs stay available. On `failed`, read `data.error_code` and `data.error_message`: the reserved amount was returned to your balance, and `data.retryable` says whether sending the same request again can succeed.## Input modes| Mode                 | Required inputs                                                                   | Notes                                                           |

string
RequiredThe model to run.**Value**: `kling-v3`**If the value is wrong**- Missing: `"model" is required`
- An image model sent to this endpoint: `"model" nano-banana-2 is served by POST /v1/images/tasks, not this endpoint`prompt
string
RequiredWhat happens in the video: subject, action, camera movement and style.**Length**: 1–5000 characters- Length is counted in characters (a CJK character counts as one).
- It is required in every mode, including multi-shot, where each shot also has its own prompt in `multi_prompt`.**If the value is wrong**- Missing: `"prompt" is required`
- Empty or longer than the limit: `"prompt" has an unsupported length`images
string[]
OptionalA first frame, or a first and a last frame.**Items**: 1–2  \
Each item is a public `https://` URL. For a local file, [upload it first](/quick-guide#upload-an-input-file) with `POST /v1/files` and pass the returned `data.url`.- One link: the video starts from this image. Two links: `images[0]` is the first frame and `images[1]` the last.
- Multi-shot (`multi_shots: true`) takes exactly one image.
- There are no reference-image fields on this model; pictures of a subject go in `elements`.**If the value is wrong**- More than two links: `"images" accepts at most 2 items`
- An empty array: `"images" requires at least 1 item`
- Not an https\:// link: `"images[0]" must be a public HTTPS URL`
- `multi_shots: true` with no image or two images: `Kling V3 multi-shot mode requires exactly one image`duration
integer
OptionalDefault: 5Length of the video in seconds, a whole number. It is what you are billed for.**Default**: `5`  \
**Range**: 3–15- If you leave it out, `5` is used and billed.
- With `multi_shots: true`, the `duration` of the shots in `multi_prompt` must add up to this number exactly. If you leave `duration` out, they must add up to 5.**If the value is wrong**- Outside the range, not a whole number, or sent as a string: `"duration" is outside its supported range`
- Multi-shot lengths that do not add up to `duration`: `Kling V3 shot durations must sum to duration`aspect_ratio
string
OptionalDefault: 16:9Shape of the video as width:height.**Allowed values**: `16:9`, `9:16`, `1:1`  \
**Default**: `16:9`- The default is `16:9`.**If the value is wrong**- A value not in the list: `"aspect_ratio" must be one of: [16:9 9:16 1:1]`resolution
string
OptionalDefault: proThe quality tier: `std` renders at 720p, `pro` renders at 1080p. `pro` costs more per second. The names are `std` and `pro`, not pixel sizes.**Allowed values**: `std`, `pro`  \
**Default**: `pro`- If you leave it out, `pro` is used and billed.
- `4K`, `720p` and `1080p` are not accepted: send `std` or `pro`.**If the value is wrong**- A value not in the list (for example `720p` or `4K`): `"resolution" must be one of: [std pro]`sound
boolean
OptionalWhether the video has a generated soundtrack.- If you leave it out, sound follows `multi_shots`: on for a multi-shot request, off otherwise. Send `true` or `false` to decide for yourself.**If the value is wrong**- Not true or false: `"sound" must be a boolean`multi_shots
boolean
OptionalDefault: falseTurns on storyboard mode: the video is made of the shots listed in `multi_prompt`. The default is `false`.**Default**: `false`- Needs exactly one image in `images` and a `multi_prompt` whose shot lengths add up to `duration`. Without `multi_shots: true`, `multi_prompt` is refused.
- Checks run in this order: one image, then `multi_prompt` present, then the lengths.**If the value is wrong**- Not true or false: `"multi_shots" must be a boolean`
- No image or more than one image: `Kling V3 multi-shot mode requires exactly one image`
- `multi_prompt` missing: `Kling V3 multi-shot mode requires multi_prompt`
- Shot lengths do not add up to `duration`: `Kling V3 shot durations must sum to duration`multi_prompt
object[]
OptionalThe shots of a multi-shot video, in order: one to five objects, each with its own prompt and length.**Items**: 1–5- Each shot is an object with two required fields, and no others are accepted:
- `multi_prompt[].prompt` (string, required): what happens in this shot, 1 to 500 characters.
- `multi_prompt[].duration` (integer, required): the length of this shot in whole seconds, 1 to 12.
- The shot lengths must add up to the request’s `duration` (5 when `duration` is left out), and that total is at most 15.
- Only valid with `multi_shots: true`.**If the value is wrong**- Sent without `multi_shots: true`: `"multi_prompt" requires multi_shots=true`
- More than five shots: `"multi_prompt" accepts at most 5 items`
- An empty array: `"multi_prompt" requires at least 1 item`
- A shot without `prompt`: `"prompt" is required in "multi_prompt[0]"`
- A shot without `duration`: `"duration" is required in "multi_prompt[0]"`
- A shot prompt that is empty or over 500 characters: `"multi_prompt[0].prompt" has an unsupported length`
- A shot length outside 1 to 12 or not a whole number: `"multi_prompt[0].duration" is outside its supported range`
- A key other than `prompt` and `duration`: `field "name" is not supported in "multi_prompt[0]"`
- Shot lengths do not add up to `duration`: `Kling V3 shot durations must sum to duration`elements
object[]
OptionalUp to three named subjects (a character, a product, a prop), each defined once with pictures.**Items**: ≤ 3- An array of at most three objects. Each object accepts these keys and no others:
- `elements[].name` (string, required): the element’s name, at least 1 character.
- `elements[].description` (string, optional): what the element is. If you leave it out, the `name` is used as the description.
- `elements[].element_input_urls` (array of strings, required): 1 to 4 public HTTPS links that show the element.
- `elements[].element_input_audio_urls` (array of strings, optional): exactly one public HTTPS audio link for the element.
- `elements[].start_time` and `elements[].end_time` (integers, optional): times in milliseconds, each a whole number from 0 to 30000. Send both or neither. `end_time` must be greater than `start_time`, and `end_time - start_time` must be from 3000 to 8000 (3 to 8 seconds).
- The limits on links apply to each element on its own: every entry may have its own four links and one audio link.**If the value is wrong**- More than three elements: `"elements" accepts at most 3 items`
- An element that is not an object: `"elements[0]" must be an object`
- An element without `name`: `"name" is required in "elements[0]"`
- An element without `element_input_urls`: `"element_input_urls" is required in "elements[0]"`
- An empty `name`: `"elements[0].name" has an unsupported length`
- More than four links: `"elements[0].element_input_urls" accepts at most 4 items`
- An empty `element_input_urls` array: `"elements[0].element_input_urls" requires at least 1 item`
- A link that is not https\://: `"elements[0].element_input_urls[1]" must be a public HTTPS URL`
- More than one audio link: `"elements[0].element_input_audio_urls" accepts at most 1 items`
- `start_time` or `end_time` outside 0 to 30000, or not whole: `"elements[0].start_time" is outside its supported range`
- A key that an element does not accept: `field "color" is not supported in "elements[0]"`
- Only one of `start_time` and `end_time`, `end_time` not after `start_time`, or a segment shorter than 3 s or longer than 8 s: `Kling V3 element segment must provide a 3-8 second start_time/end_time range`## Input media limitsThe gateway reads every input before the task is created and refuses one outside these limits with a `400 bad_request` that names the input. Nothing is charged.- The gateway checks only that every image, element link and audio link is a public HTTPS link. It does not measure size, format or dimensions before the task is created, so an input the model cannot use fails the task after submission; the message says what to change and the whole reservation is returned.
- Have a local file? Upload it with `POST /v1/files` and pass the returned `data.url`.## Multi-shot rulesThese are checked in this order when the task is created; a request that breaks one is refused with `400 bad_request` and costs nothing.| Rule                                                         | Message                                               |
| ------------------------------------------------------------ | ----------------------------------------------------- |
| `multi_prompt` is sent but `multi_shots` is not `true`       | `"multi_prompt" requires multi_shots=true`            |
| `multi_shots: true` without exactly one image in `images`    | `Kling V3 multi-shot mode requires exactly one image` |
| `multi_shots: true` without `multi_prompt`                   | `Kling V3 multi-shot mode requires multi_prompt`      |
| The shot lengths do not add up to `duration` (5 if left out) | `Kling V3 shot durations must sum to duration`        |- Text-only multi-shot is not available: a multi-shot video always starts from one image.
- A multi-shot request is billed for `duration` seconds, which is the sum of its shots.## Fields this model does not acceptSending one of these is refused before anything is charged, instead of being ignored:- `reference_images`, `reference_videos`, `reference_audios`, `generate_audio`, `seed`, `quality`, `watermark`, `task_type`, `output_format` → `field "reference_images" is not supported by model kling-v3` (with the field you sent).
- Any other unknown field → `unknown field: <name>`.## Request examples```bash title="cURL"

```## Billing- `sound` does not change the price: it depends on `duration` and `resolution` only, so the price rows apply with or without sound.
- The price is per second of video, at the tier you choose: the list below shows 8-second clips, so divide by 8 for the rate (about $0.11 per second at `std` and $0.13 at `pro`).
- The number of seconds is `duration`, or 5 when you leave it out; for a multi-shot request it is the sum of the shots, which equals `duration`. `usage.billable_duration_seconds` on the task shows it.
- The price is reserved when the task is created and settled when the video is ready. A failed task, including one refused by moderation after submission, is refunded in full.## Common errors| Error or symptom                                                                   | Cause                                                                                                                                                                              | Fix                                                                                       |

Reference: https://docs.beatapi.io/api-reference/video-api/kling-3

## Authentication

- `Authorization` header (bearer token, required) — Send your API key as `Authorization: Bearer <BEATAPI_API_KEY>`.

## Servers

- `https://api.beatapi.io` (Direct, default)
- `https://api.beatapi.io` (API)

## Request

### Headers

- `Idempotency-Key` (string, optional) — Send the body as JSON with `Content-Type: application/json`. `Idempotency-Key` is optional: send a unique value (at most 255 characters) per logical request and reuse it only to retry that exact body. Within 24 hours a retry with the same key and body returns the first response again with `Idempotent-Replayed: true`; the same key with a different body returns `409 idempotency_conflict`. Responses other than 2xx are not stored, so a retry after a 400 or 402 runs again.

### Body (application/json)

This endpoint expects a Kling3VideoRequest.

- `model` (enum, required) — The model to run. **Value**: `kling-v3` **If the value is wrong** - Missing: `"model" is required` - An image model sent to this endpoint: `"model" nano-banana-2 is served by POST /v1/images/tasks, not this endpoint`
  - Allowed values: `kling-v3`
- `prompt` (string, required) — What happens in the video: subject, action, camera movement and style. **Length**: 1–5000 characters - Length is counted in characters (a CJK character counts as one). - It is required in every mode, including multi-shot, where each shot also has its own prompt in `multi_prompt`. **If the value is wrong** - Missing: `"prompt" is required` - Empty or longer than the limit: `"prompt" has an unsupported length`
- `aspect_ratio` (enum, optional, default: 16:9) — Shape of the video as width:height. **Allowed values**: `16:9`, `9:16`, `1:1` **Default**: `16:9` - The default is `16:9`. **If the value is wrong** - A value not in the list: `"aspect_ratio" must be one of: [16:9 9:16 1:1]`
  - Allowed values: `16:9`, `9:16`, `1:1`
- `duration` (integer, optional, default: 5) — Length of the video in seconds, a whole number. It is what you are billed for. **Default**: `5` **Range**: 3–15 - If you leave it out, `5` is used and billed. - With `multi_shots: true`, the `duration` of the shots in `multi_prompt` must add up to this number exactly. If you leave `duration` out, they must add up to 5. **If the value is wrong** - Outside the range, not a whole number, or sent as a string: `"duration" is outside its supported range` - Multi-shot lengths that do not add up to `duration`: `Kling V3 shot durations must sum to duration`
- `elements` (list of Kling3VideoRequestElementsItems, optional) — Up to three named subjects (a character, a product, a prop), each defined once with pictures. **Items**: ≤ 3 - An array of at most three objects. Each object accepts these keys and no others: - `elements[].name` (string, required): the element’s name, at least 1 character. - `elements[].description` (string, optional): what the element is. If you leave it out, the `name` is used as the description. - `elements[].element_input_urls` (array of strings, required): 1 to 4 public HTTPS links that show the element. - `elements[].element_input_audio_urls` (array of strings, optional): exactly one public HTTPS audio link for the element. - `elements[].start_time` and `elements[].end_time` (integers, optional): times in milliseconds, each a whole number from 0 to 30000. Send both or neither. `end_time` must be greater than `start_time`, and `end_time - start_time` must be from 3000 to 8000 (3 to 8 seconds). - The limits on links apply to each element on its own: every entry may have its own four links and one audio link. **If the value is wrong** - More than three elements: `"elements" accepts at most 3 items` - An element that is not an object: `"elements[0]" must be an object` - An element without `name`: `"name" is required in "elements[0]"` - An element without `element_input_urls`: `"element_input_urls" is required in "elements[0]"` - An empty `name`: `"elements[0].name" has an unsupported length` - More than four links: `"elements[0].element_input_urls" accepts at most 4 items` - An empty `element_input_urls` array: `"elements[0].element_input_urls" requires at least 1 item` - A link that is not https://: `"elements[0].element_input_urls[1]" must be a public HTTPS URL` - More than one audio link: `"elements[0].element_input_audio_urls" accepts at most 1 items` - `start_time` or `end_time` outside 0 to 30000, or not whole: `"elements[0].start_time" is outside its supported range` - A key that an element does not accept: `field "color" is not supported in "elements[0]"` - Only one of `start_time` and `end_time`, `end_time` not after `start_time`, or a segment shorter than 3 s or longer than 8 s: `Kling V3 element segment must provide a 3-8 second start_time/end_time range`
- `images` (list of string, optional) — A first frame, or a first and a last frame. **Items**: 1–2 Each item is a public `https://` URL. For a local file, [upload it first](/quick-guide#upload-an-input-file) with `POST /v1/files` and pass the returned `data.url`. - One link: the video starts from this image. Two links: `images[0]` is the first frame and `images[1]` the last. - Multi-shot (`multi_shots: true`) takes exactly one image. - There are no reference-image fields on this model; pictures of a subject go in `elements`. **If the value is wrong** - More than two links: `"images" accepts at most 2 items` - An empty array: `"images" requires at least 1 item` - Not an https:// link: `"images[0]" must be a public HTTPS URL` - `multi_shots: true` with no image or two images: `Kling V3 multi-shot mode requires exactly one image`
- `multi_prompt` (list of Kling3VideoRequestMultiPromptItems, optional) — The shots of a multi-shot video, in order: one to five objects, each with its own prompt and length. **Items**: 1–5 - Each shot is an object with two required fields, and no others are accepted: - `multi_prompt[].prompt` (string, required): what happens in this shot, 1 to 500 characters. - `multi_prompt[].duration` (integer, required): the length of this shot in whole seconds, 1 to 12. - The shot lengths must add up to the request’s `duration` (5 when `duration` is left out), and that total is at most 15. - Only valid with `multi_shots: true`. **If the value is wrong** - Sent without `multi_shots: true`: `"multi_prompt" requires multi_shots=true` - More than five shots: `"multi_prompt" accepts at most 5 items` - An empty array: `"multi_prompt" requires at least 1 item` - A shot without `prompt`: `"prompt" is required in "multi_prompt[0]"` - A shot without `duration`: `"duration" is required in "multi_prompt[0]"` - A shot prompt that is empty or over 500 characters: `"multi_prompt[0].prompt" has an unsupported length` - A shot length outside 1 to 12 or not a whole number: `"multi_prompt[0].duration" is outside its supported range` - A key other than `prompt` and `duration`: `field "name" is not supported in "multi_prompt[0]"` - Shot lengths do not add up to `duration`: `Kling V3 shot durations must sum to duration`
- `multi_shots` (boolean, optional, default: false) — Turns on storyboard mode: the video is made of the shots listed in `multi_prompt`. The default is `false`. **Default**: `false` - Needs exactly one image in `images` and a `multi_prompt` whose shot lengths add up to `duration`. Without `multi_shots: true`, `multi_prompt` is refused. - Checks run in this order: one image, then `multi_prompt` present, then the lengths. **If the value is wrong** - Not true or false: `"multi_shots" must be a boolean` - No image or more than one image: `Kling V3 multi-shot mode requires exactly one image` - `multi_prompt` missing: `Kling V3 multi-shot mode requires multi_prompt` - Shot lengths do not add up to `duration`: `Kling V3 shot durations must sum to duration`
- `resolution` (enum, optional, default: pro) — The quality tier: `std` renders at 720p, `pro` renders at 1080p. `pro` costs more per second. The names are `std` and `pro`, not pixel sizes. **Allowed values**: `std`, `pro` **Default**: `pro` - If you leave it out, `pro` is used and billed. - `4K`, `720p` and `1080p` are not accepted: send `std` or `pro`. **If the value is wrong** - A value not in the list (for example `720p` or `4K`): `"resolution" must be one of: [std pro]`
  - Allowed values: `std`, `pro`
- `sound` (boolean, optional) — Whether the video has a generated soundtrack. - If you leave it out, sound follows `multi_shots`: on for a multi-shot request, off otherwise. Send `true` or `false` to decide for yourself. **If the value is wrong** - Not true or false: `"sound" must be a boolean`
