# Kling 3

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

Generate 3–15 second videos from text or frames, with optional multi-shot and reusable-element controls up to 4K.

### Supported modes

| Mode             | Required input                                   | Rules                                                          |
| ---------------- | ------------------------------------------------ | -------------------------------------------------------------- |
| Text to video    | `model`, `prompt`                                | Omit `images`, `multi_prompt`, and `elements`.                 |
| First frame      | `model`, `prompt`, `images`                      | Provide one image URL; provide two for first and last frames.  |
| Multi-shot       | `model`, `prompt`, `multi_shots`, `multi_prompt` | Set `multi_shots=true`; shot durations must sum to `duration`. |
| Reusable element | `model`, `prompt`, `elements`                    | Provide up to three named image or video reference elements.   |

**Async flow:** Create the task, save `data.id`, then [poll the Task](/quick-guide#get-task-status) with `GET /v1/tasks/{task_id}`. On `succeeded`, read `data.output.media`. On `failed`, read `data.error_code` and `data.error_message`, then follow the [error and retry policy](/quick-guide#errors-and-retry-policy).

**Using a local file?** [upload a local input](/quick-guide#upload-an-input-file) first and pass the returned `data.url`.

## Authentication

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

## Request

### Headers

- `Idempotency-Key` (string, optional)

### Body (application/json)

This endpoint expects a Kling3VideoRequest.

- `model` ("kling-3", required) — Must be `kling-3`.
- `prompt` (string, required) — Video generation instructions.
- `images` (list of string, optional) — One first-frame image or first- and last-frame images as public HTTPS URLs. Multi-shot mode accepts exactly one.
- `duration` (integer, optional, default: 5) — Requested output duration in seconds.
- `aspect_ratio` (enum, optional) — Defaults to 16:9 for text generation. Omit it with frame images to adapt to the input aspect ratio.
  - Allowed values: `16:9`, `9:16`, `1:1`
- `resolution` (enum, optional, default: pro) — Output quality tier.
  - Allowed values: `std`, `pro`, `4K`
- `sound` (boolean, optional) — Generate synchronized sound. Defaults to true in multi-shot mode.
- `multi_shots` (boolean, optional, default: false) — Enable storyboard-style multi-shot generation.
- `multi_prompt` (list of KlingShot, optional) — Shot definitions required when `multi_shots=true`.
- `elements` (list of KlingElement, optional) — Up to three reusable subject or object references.

## Response

### 201

Video generation task accepted

## Errors

### 400 Bad Request Error

Malformed JSON or a field, value or combination this endpoint does not accept (`bad_request`; the message names the field), or input refused by moderation (`content_policy_violation`). Not retryable unchanged.

- `error` (ErrorError, required) — Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

### 401 Unauthorized Error

No API key (`missing_api_key`), or a key that is wrong, expired, disabled or exhausted (`invalid_api_key`; the message says which). Send it as `Authorization: Bearer <key>`; the key works with or without the `sk-` prefix. Not retryable.

- `error` (ErrorError, required) — Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

### 402 Payment Required Error

Insufficient balance (`insufficient_credits`). The account balance is zero or below the price of this request. Top up, then send it again; not retryable before that.

- `error` (ErrorError, required) — Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

### 403 Forbidden Error

The key or account is not permitted to make this call (`forbidden`), for example a model that is not available on free credit (a top-up unlocks it), a request from outside the key's IP allowlist, or a model outside the key's group. Not retryable.

- `error` (ErrorError, required) — Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

### 409 Conflict Error

The `Idempotency-Key` was already used with a different request body, or the first request with it is still being processed (`idempotency_conflict`). Not retryable unchanged.

- `error` (ErrorError, required) — Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

### 429 Too Many Requests Error

Too many requests (`rate_limit_exceeded`, including the free-model limits) or too many tasks processing at once (`user_concurrency_exceeded`). Retryable after `Retry-After` seconds (also `error.retry_after_seconds`).

- `error` (ErrorError, required) — Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

### 500 Internal Server Error

Unexpected internal error (`internal_error`). Retryable; keep `request_id` for support if it persists.

- `error` (ErrorError, required) — Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

### 503 Service Unavailable Error

The request could not be completed (`processing_unavailable`, `processing_timeout`, `processing_failed` or `result_transfer_failed`). Nothing was charged. Retryable with backoff; `Retry-After` is sent when the wait is known. BeatAPI does not answer 502 or 504.

- `error` (ErrorError, required) — Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

## Types

### KlingShot

- `prompt` (string, required) — Instructions for this shot.
- `duration` (integer, required) — Shot duration in seconds. All shot durations must sum to the task duration.

### KlingElement

Use 2-4 image URLs or one video URL. A video element may include one audio URL and a 3-8 second segment in milliseconds.

- `name` (string, required) — Stable name used to reference this element in the prompt.
- `element_input_urls` (list of string, required) — Two to four image URLs, or one video URL.
- `description` (string, optional) — Optional description of the subject or object.
- `element_input_audio_urls` (list of string, optional) — Optional audio URL used with a video element.
- `start_time` (integer, optional) — Video element segment start time in milliseconds.
- `end_time` (integer, optional) — Video element segment end time in milliseconds. The segment must be 3-8 seconds.

### ErrorError

Structured BeatAPI error. Use `code` (or `retryable`) for program logic and retain `request_id` for support.

- `code` (enum, required) — Stable machine-readable error code. `unauthorized` is the deprecated name for a 401; since 2026-09-29 a 401 is `missing_api_key` or `invalid_api_key`. Treat a legacy `unauthorized` like `invalid_api_key`.
  - Allowed values: `bad_request`, `missing_api_key`, `invalid_api_key`, `unauthorized`, `forbidden`, `not_found`, `insufficient_credits`, `idempotency_conflict`, `user_concurrency_exceeded`, `rate_limit_exceeded`, `content_policy_violation`, `processing_unavailable`, `processing_failed`, `processing_timeout`, `result_transfer_failed`, `invalid_signature`, `realtime_disabled`, `realtime_capacity_unavailable`, `realtime_session_expired`, `origin_not_allowed`, `invalid_client_secret`, `transport_not_allowed`, `internal_error`
- `message` (string, required) — English sentence that states the cause; for `bad_request` it names the field. Written for people and logs, not for parsing.
- `retryable` (boolean, required) — Whether making the same call again could succeed. Present on every error; branch on it instead of the status code. True for 429, 500 and 503 (rate_limit_exceeded, user_concurrency_exceeded, internal_error, processing_unavailable, processing_timeout, processing_failed, result_transfer_failed, realtime_capacity_unavailable). False for a request, key or balance that must change first (bad_request, content_policy_violation, missing_api_key, invalid_api_key, insufficient_credits, forbidden, not_found, idempotency_conflict, realtime_disabled and the other realtime credential codes).
- `request_id` (string, required) — Correlation ID to retain for BeatAPI support.
- `retry_after_seconds` (integer, optional) — Seconds to wait before retrying. Present on every 429, and on a 503 when the wait is known; the same value is sent in the `Retry-After` header.
- `docs` (string, optional) — The public Skill page that says what to do about an error. Present on errors answered by the capability endpoints (`/v1/capabilities/search`, `/v1/capabilities/inspect`, `/v1/capabilities/run`); absent on every other endpoint.
