# Grok Imagine Video 1.5

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

根据文本、一张首帧图或最多七张参考图，生成 480p、720p 或 1080p、时长 1–15 秒的视频；按视频秒数计费。- 异步：创建请求返回任务 ID，任务成功后才能拿到视频。
- 三种输入方式：纯文本、一张首帧图，或最多七张参考图（1080p 最多一张）。
- 时长可取 1 到 15 之间的任意整数秒。不传 `duration` 则默认 8 秒，分辨率默认 480p。
- 按所选分辨率下的视频秒数计费，4 秒的片段价格是 8 秒的一半。失败的任务不收费。POST/v1/videos/tasks试一试在调试窗口里打开本模型，填入你的 BeatAPI API 密钥即可创建任务。调用是真实的，费用从你自己的余额中扣除。## 接口与鉴权`POST https://api.beatapi.io/v1/videos/tasks`Authorization
string
必需你的 BeatAPI API 密钥，以 `Bearer <BEATAPI_API_KEY>` 形式发送。在[控制台](https://beatapi.io/dashboard)创建密钥。密钥只能保存在你的服务端，不要放进浏览器或移动端应用。请求体使用 JSON，并设置 `Content-Type: application/json`。`Idempotency-Key` 为可选：每个逻辑请求发送一个唯一值（最长 255 个字符），仅在重试完全相同的请求体时复用。24 小时内，用相同的键和请求体重试会再次返回第一次的响应，并带上 `Idempotent-Replayed: true`；相同的键搭配不同的请求体则返回 `409 idempotency_conflict`。非 2xx 的响应不会被保存，因此 400 或 402 之后的重试会重新执行。## 请求流程向接口 `POST` 下方的参数。返回 `201` 表示任务已被接受，其价格已从你的余额中预留；任务在后台运行。保存 `data.id`。调用 `GET /v1/tasks/{task_id}`，两次调用之间等待 `data.poll_after_seconds` 秒（图片 5 秒，视频 8 秒），直到 `status` 为 `succeeded` 或 `failed`。也可以为 `task.succeeded` 和 `task.failed` 注册 [Webhook](/webhooks)；仍需保留轮询作为兜底，因为因处理超时而终止的任务不会发送事件。状态为 `succeeded` 时，下载每个 `data.output.media[].url` 并保存你需要的文件；BeatAPI 不承诺结果链接的保留时长。状态为 `failed` 时，读取 `data.error_code` 和 `data.error_message`：预扣的金额已退回你的余额，`data.retryable` 表示再次发送相同请求是否可能成功。## 输入模式| 模式   | 必填输入                                         | 说明                                 |
| ---- | -------------------------------------------- | ---------------------------------- |
| 文生视频 | `model`、`prompt`                             | 不要传 `images` 和 `reference_images`。 |
| 首帧   | `model`、`prompt`、`images`（1 个链接）             | 视频从这张图开始。不要传 `aspect_ratio`。       |
| 参考图  | `model`、`prompt`、`reference_images`（1–7 个链接） | 不能与 `images` 同时使用。1080p 下最多传一张参考图。 |## 请求参数model
string
必需要运行的模型。**取值**：`grok-imagine-video-1.5`**取值有误时**- 未传：`"model" is required`
- 把图片模型发到了这个端点：`"model" nano-banana-2 is served by POST /v1/images/tasks, not this endpoint`prompt
string
必需视频里发生什么：主体、动作、运镜和风格。使用参考图时，说明每张图的用途。**长度**：1–4096 个字符- 在提示词中按位置引用参考图，例如“第一张参考图”。
- 很长的提示词，或使用多字节字符的语言写成的提示词，可能通过这一长度检查，却在任务创建后仍被拒绝；失败的任务会说明需要缩短什么，并会退款。**取值有误时**- 未传：`"prompt" is required`
- 为空或超过长度上限：`"prompt" has an unsupported length`images
string[]
可选一张图片，作为视频的首帧。**数量**：1–1  \
每一项都必须是公网 `https://` 链接。本地文件请先[上传](/quick-guide#upload-an-input-file)（`POST /v1/files`），再传入返回的 `data.url`。- 只能传一个链接。若要传入多张用于引导视频、但不作为首帧的图片，请使用 `reference_images`。
- 不要同时传 `aspect_ratio` 和 `images`。**取值有误时**- 空数组：`"images" requires at least 1 item`
- 多于一个链接：`"images" accepts at most 1 items`
- 与 `reference_images` 同时传：`Cannot combine "images" with reference inputs in one task`
- 不是 https\:// 链接：`"images[0]" must be a public HTTPS URL`
- 与 `aspect_ratio` 同时传：`Grok Imagine Video 1.5 does not accept aspect_ratio with a single image`reference_images
string[]
可选一到七张图片，用来引导视频中的角色、产品或风格。**数量**：1–7  \
每一项都必须是公网 `https://` 链接。本地文件请先[上传](/quick-guide#upload-an-input-file)（`POST /v1/files`），再传入返回的 `data.url`。- 图片按列表顺序使用；在提示词中按位置引用。
- 在 `1080p` 下最多传一张参考图。需要更多图片时，请使用 `480p` 或 `720p`。**取值有误时**- 多于七个链接：`"reference_images" accepts at most 7 items`
- 空数组：`"reference_images" requires at least 1 item`
- 与 `images` 同时传：`Cannot combine "images" with reference inputs in one task`
- `1080p` 下传了多于一张图：`Grok Imagine Video 1.5 1080p accepts at most one image`duration
integer
可选默认值: 8视频时长，单位为秒，须为整数。计费以它为准。**默认值**：`8`  \
**范围**：1–15- 不传时使用并按 `8` 计费。任务上的 `usage.billable_duration_seconds` 显示价格所依据的秒数。**取值有误时**- 超出范围、不是整数，或以字符串传入：`"duration" is outside its supported range`aspect_ratio
string
可选默认值: 16:9视频的宽高比（宽:高）。`auto` 表示由模型决定。**可选值**：`1:1`, `16:9`, `9:16`, `3:2`, `2:3`, `auto`  \
**默认值**：`16:9`- 文生视频或参考图模式下不传则使用 `16:9`。在 `images` 中只传一张首帧时不要传此字段：画面形状由首帧决定。**取值有误时**- 取值不在列表中：`"aspect_ratio" must be one of: [1:1 16:9 9:16 3:2 2:3 auto]`
- 与 `images` 同时传：`Grok Imagine Video 1.5 does not accept aspect_ratio with a single image`resolution
string
可选默认值: 480p输出分辨率。分辨率越高，每秒价格越高。**可选值**：`480p`, `720p`, `1080p`  \
**默认值**：`480p`- 只接受小写。默认值为 `480p`，是最便宜的档位。
- 使用 `reference_images` 时，`1080p` 最多只能传一张图。**取值有误时**- 取值不在列表中（例如 `1080P`）：`"resolution" must be one of: [480p 720p 1080p]`
- `1080p` 下传了多于一张参考图：`Grok Imagine Video 1.5 1080p accepts at most one image`网关还会在创建任务之前检查以下组合：- `images` 不能与参考素材字段同时使用。## 输入素材限制网关会在创建任务之前读取每一项输入，超出这些限制的输入会被拒绝，并返回点名该输入的 `400 bad_request`。不扣费。- 网关在创建任务前只检查每张图片是否为公开 HTTPS 链接，不会检查大小、格式或尺寸。因此模型无法使用的图片会在提交后导致任务失败；失败信息会说明需要修改什么，并全额退还预扣费用。
- 只有本地文件？先用 `POST /v1/files` 上传，再传入返回的 `data.url`。## 该模型不接受的字段传入下列字段会在扣费前被拒绝，而不是被忽略：- `reference_videos`、`reference_audios`、`generate_audio`、`seed`、`quality`、`sound`、`watermark`、`task_type`、`output_format` → `field "reference_videos" is not supported by model grok-imagine-video-1.5`（其中是你传入的字段名）。
- 其他任何未知字段 → `unknown field: <name>`。## 取决于模式的规则| 模式           | `aspect_ratio` | `reference_images` | `resolution`  |
| ------------ | -------------- | ------------------ | ------------- |
| 文生视频         | 可选，不传则为 `16:9` | 不传                 | 任意            |
| 首帧（`images`） | 不要传            | 不传                 | 任意            |
| 参考图          | 可选，不传则为 `16:9` | 1–7 个链接            | `1080p` 最多一张图 |- 这些规则在创建任务时检查；违反任一规则的请求会被 `400 bad_request` 拒绝，且不收费。## 请求示例```bash title="cURL"

## 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) — 请求体使用 JSON，并设置 `Content-Type: application/json`。`Idempotency-Key` 为可选：每个逻辑请求发送一个唯一值（最长 255 个字符），仅在重试完全相同的请求体时复用。24 小时内，用相同的键和请求体重试会再次返回第一次的响应，并带上 `Idempotent-Replayed: true`；相同的键搭配不同的请求体则返回 `409 idempotency_conflict`。非 2xx 的响应不会被保存，因此 400 或 402 之后的重试会重新执行。

### Body (application/json)

This endpoint expects a GrokImagineVideo15Request.

- `model` (enum, required) — 要运行的模型。 **取值**：`grok-imagine-video-1.5` **取值有误时** - 未传：`"model" is required` - 把图片模型发到了这个端点：`"model" nano-banana-2 is served by POST /v1/images/tasks, not this endpoint`
  - Allowed values: `grok-imagine-video-1.5`
- `prompt` (string, required) — 视频里发生什么：主体、动作、运镜和风格。使用参考图时，说明每张图的用途。 **长度**：1–4096 个字符 - 在提示词中按位置引用参考图，例如“第一张参考图”。 - 很长的提示词，或使用多字节字符的语言写成的提示词，可能通过这一长度检查，却在任务创建后仍被拒绝；失败的任务会说明需要缩短什么，并会退款。 **取值有误时** - 未传：`"prompt" is required` - 为空或超过长度上限：`"prompt" has an unsupported length`
- `aspect_ratio` (enum, optional, default: 16:9) — 视频的宽高比（宽:高）。`auto` 表示由模型决定。 **可选值**：`1:1`, `16:9`, `9:16`, `3:2`, `2:3`, `auto` **默认值**：`16:9` - 文生视频或参考图模式下不传则使用 `16:9`。在 `images` 中只传一张首帧时不要传此字段：画面形状由首帧决定。 **取值有误时** - 取值不在列表中：`"aspect_ratio" must be one of: [1:1 16:9 9:16 3:2 2:3 auto]` - 与 `images` 同时传：`Grok Imagine Video 1.5 does not accept aspect_ratio with a single image`
  - Allowed values: `1:1`, `16:9`, `9:16`, `3:2`, `2:3`, `auto`
- `duration` (integer, optional, default: 8) — 视频时长，单位为秒，须为整数。计费以它为准。 **默认值**：`8` **范围**：1–15 - 不传时使用并按 `8` 计费。任务上的 `usage.billable_duration_seconds` 显示价格所依据的秒数。 **取值有误时** - 超出范围、不是整数，或以字符串传入：`"duration" is outside its supported range`
- `images` (list of string, optional) — 一张图片，作为视频的首帧。 **数量**：1–1 每一项都必须是公网 `https://` 链接。本地文件请先[上传](/quick-guide#upload-an-input-file)（`POST /v1/files`），再传入返回的 `data.url`。 - 只能传一个链接。若要传入多张用于引导视频、但不作为首帧的图片，请使用 `reference_images`。 - 不要同时传 `aspect_ratio` 和 `images`。 **取值有误时** - 空数组：`"images" requires at least 1 item` - 多于一个链接：`"images" accepts at most 1 items` - 与 `reference_images` 同时传：`Cannot combine "images" with reference inputs in one task` - 不是 https:// 链接：`"images[0]" must be a public HTTPS URL` - 与 `aspect_ratio` 同时传：`Grok Imagine Video 1.5 does not accept aspect_ratio with a single image`
- `reference_images` (list of string, optional) — 一到七张图片，用来引导视频中的角色、产品或风格。 **数量**：1–7 每一项都必须是公网 `https://` 链接。本地文件请先[上传](/quick-guide#upload-an-input-file)（`POST /v1/files`），再传入返回的 `data.url`。 - 图片按列表顺序使用；在提示词中按位置引用。 - 在 `1080p` 下最多传一张参考图。需要更多图片时，请使用 `480p` 或 `720p`。 **取值有误时** - 多于七个链接：`"reference_images" accepts at most 7 items` - 空数组：`"reference_images" requires at least 1 item` - 与 `images` 同时传：`Cannot combine "images" with reference inputs in one task` - `1080p` 下传了多于一张图：`Grok Imagine Video 1.5 1080p accepts at most one image`
- `resolution` (enum, optional, default: 480p) — 输出分辨率。分辨率越高，每秒价格越高。 **可选值**：`480p`, `720p`, `1080p` **默认值**：`480p` - 只接受小写。默认值为 `480p`，是最便宜的档位。 - 使用 `reference_images` 时，`1080p` 最多只能传一张图。 **取值有误时** - 取值不在列表中（例如 `1080P`）：`"resolution" must be one of: [480p 720p 1080p]` - `1080p` 下传了多于一张参考图：`Grok Imagine Video 1.5 1080p accepts at most one image`
  - Allowed values: `480p`, `720p`, `1080p`
