# Wan 3.0

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

根据文本、一张或多张图片，或参考视频与音频，生成 2～30 秒的 720p 或 1080p 视频。- 异步：创建调用返回任务 ID，任务成功后即可获得视频。
- 单次请求可生成 2 到 30 秒的片段；`duration` 为整数秒。
- 四种输入方式：仅文本、一张图片、多张图片（最多 10 张），或参考视频与音频（各最多 5 个）。图片与参考素材不能混用。
- 按所选分辨率和请求的秒数计费。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。## 模型 ID两个 Wan 3.0 模型共用此端点，接受完全相同的请求。下表数值直接取自网关契约。| 模型 ID           | `duration`（秒） | `resolution`    | 图片上限 | 参考视频上限 | 参考音频上限 | 说明                                                    |

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`                                             | 不要发送 `images` 和任何参考字段。             |
| 单张图片 | `model`、`prompt`、`images`（1 个链接）                              | 视频由这张图片生成。                         |
| 多张图片 | `model`、`prompt`、`images`（2 到 10 个链接）                         | 图片按列表顺序传给模型。                       |
| 参考素材 | `model`、`prompt`，以及 `reference_videos` 和/或 `reference_audios` | 最多 5 个视频和 5 段音频。不能与 `images` 同时使用。 |## 请求参数model
string
必需要运行的模型。**取值**：`wan-3.0`**取值有误时**- 缺失：`"model" is required`
- 向此端点发送了图片模型：`"model" nano-banana-2 is served by POST /v1/images/tasks, not this endpoint`prompt
string
必需视频中发生的内容：主体、动作和镜头。使用参考素材时，说明每个输入的用途。**长度**：1–5000 个字符- 长度按字符计算（一个中日韩文字算一个字符）。**取值有误时**- 缺失：`"prompt" is required`
- 为空或超出长度上限：`"prompt" has an unsupported length`
- 不是字符串：`"prompt" must be a string`images
string[]
可选用来生成视频的图片：一张，或按期望使用顺序排列的多张。**数量**：1–10  \
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`。- 每个链接必须是公开的 `https://` URL。创建任务时，网关不会下载或检测这些文件。
- 不能与 `reference_videos` 或 `reference_audios` 同时发送。
- 省略 `aspect_ratio` 和 `resolution` 时沿用默认值（`16:9`、`720p`），发送图片时也一样：网关不会从图片中读取这两项。请自行指定想要的画面形状。**取值有误时**- 超过 10 个链接：`"images" accepts at most 10 items`
- 空数组：`"images" requires at least 1 item`
- 不是数组：`"images" must be an array`
- 不是 https\:// 链接：`"images[0]" must be a public HTTPS URL`
- 与参考字段同时使用：`Cannot combine "images" with reference inputs in one task`reference_videos
string[]
可选模型用作新视频参考的视频。**数量**：1–5  \
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`。- 公开的 `https://` 链接，最多 5 个。创建任务时网关不会下载、检测或限制它们，因此模型无法使用的片段会在之后导致任务失败（会退款）。
- 不能与 `images` 同时发送。**取值有误时**- 超过 5 个链接：`"reference_videos" accepts at most 5 items`
- 与 `images` 同时使用：`Cannot combine "images" with reference inputs in one task`reference_audios
string[]
可选模型用作参考的音乐、人声或音效片段。**数量**：1–5  \
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`。- 公开的 `https://` 链接，最多 5 个。创建任务时不会下载或检测。
- 不能与 `images` 同时发送。**取值有误时**- 超过 5 个链接：`"reference_audios" accepts at most 5 items`duration
integer
可选默认值: 5视频长度，单位为秒，须为整数。**默认值**：`5`  \
**范围**：2–30- 省略时使用 `5` 并按其计费。
- 按秒计费（见“计费”），因此这是影响价格的主要因素。
- 不接受 `-1`（由模型决定长度）：请发送范围内的整数。**取值有误时**- 超出 2～30、不是整数，或以字符串发送：`"duration" is outside its supported range`aspect_ratio
string
可选默认值: 16:9视频的宽高比，格式为 宽:高。**可选值**：`16:9`, `9:16`, `1:1`, `4:3`, `3:4`  \
**默认值**：`16:9`- 省略时使用 `16:9`，发送图片或参考素材时也一样。
- 此模型不提供 `adaptive`。**取值有误时**- 取值不在列表中：`"aspect_ratio" must be one of: [16:9 9:16 1:1 4:3 3:4]`resolution
string
可选默认值: 720p输出分辨率。1080p 每秒的价格高于 720p。**可选值**：`720p`, `1080p`  \
**默认值**：`720p`- 仅限小写。不提供 480p。**取值有误时**- 取值不在列表中（例如 `480p` 或 `720P`）：`"resolution" must be one of: [720p 1080p]`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。- 创建任务时网关不会读取你的图片、视频或音频文件，因此此模型不检查大小、分辨率、时长或格式限制；只适用上文的字段规则。
- 模型无法获取或使用的链接会在任务创建后导致任务失败，通常报 `bad_request`（输入被内容审核拒绝时为 `content_policy_violation`），并全额退款。
- 有本地文件？用 `POST /v1/files` 上传（png、jpg、jpeg、webp、mp3、wav、aac、m4a、mp4 或 mov；最大 50 MB，视频最大 100 MB），再传入返回的 `data.url`。## 哪些输入可以一起用| 你发送的内容                                                  | 输入模式 | 是否允许                                                            |

| `images` 与 `reference_videos` 或 `reference_audios` 同时使用 | —    | 不允许：`Cannot combine "images" with reference inputs in one task` |## 此模型不接受的字段发送下列任一字段会在扣费之前被拒绝，而不是被忽略：- `reference_images`、`generate_audio`、`seed`、`quality`、`sound`、`task_type`、`output_format`、`watermark`，以及其他视频模型的字段 → `field "seed" is not supported by model wan-3.0`（其中是你发送的字段名）。图片请放进 `images`。
- 视频端点完全不认识的字段 → `unknown field: <name>`。## 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 Wan30VideoRequest.

- `model` (enum, required) — 要运行的模型。 **取值**：`wan-3.0` **取值有误时** - 缺失：`"model" is required` - 向此端点发送了图片模型：`"model" nano-banana-2 is served by POST /v1/images/tasks, not this endpoint`
  - Allowed values: `wan-3.0`
- `prompt` (string, required) — 视频中发生的内容：主体、动作和镜头。使用参考素材时，说明每个输入的用途。 **长度**：1–5000 个字符 - 长度按字符计算（一个中日韩文字算一个字符）。 **取值有误时** - 缺失：`"prompt" is required` - 为空或超出长度上限：`"prompt" has an unsupported length` - 不是字符串：`"prompt" must be a string`
- `aspect_ratio` (enum, optional, default: 16:9) — 视频的宽高比，格式为 宽:高。 **可选值**：`16:9`, `9:16`, `1:1`, `4:3`, `3:4` **默认值**：`16:9` - 省略时使用 `16:9`，发送图片或参考素材时也一样。 - 此模型不提供 `adaptive`。 **取值有误时** - 取值不在列表中：`"aspect_ratio" must be one of: [16:9 9:16 1:1 4:3 3:4]`
  - Allowed values: `16:9`, `9:16`, `1:1`, `4:3`, `3:4`
- `duration` (integer, optional, default: 5) — 视频长度，单位为秒，须为整数。 **默认值**：`5` **范围**：2–30 - 省略时使用 `5` 并按其计费。 - 按秒计费（见“计费”），因此这是影响价格的主要因素。 - 不接受 `-1`（由模型决定长度）：请发送范围内的整数。 **取值有误时** - 超出 2～30、不是整数，或以字符串发送：`"duration" is outside its supported range`
- `images` (list of string, optional) — 用来生成视频的图片：一张，或按期望使用顺序排列的多张。 **数量**：1–10 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`。 - 每个链接必须是公开的 `https://` URL。创建任务时，网关不会下载或检测这些文件。 - 不能与 `reference_videos` 或 `reference_audios` 同时发送。 - 省略 `aspect_ratio` 和 `resolution` 时沿用默认值（`16:9`、`720p`），发送图片时也一样：网关不会从图片中读取这两项。请自行指定想要的画面形状。 **取值有误时** - 超过 10 个链接：`"images" accepts at most 10 items` - 空数组：`"images" requires at least 1 item` - 不是数组：`"images" must be an array` - 不是 https:// 链接：`"images[0]" must be a public HTTPS URL` - 与参考字段同时使用：`Cannot combine "images" with reference inputs in one task`
- `reference_audios` (list of string, optional) — 模型用作参考的音乐、人声或音效片段。 **数量**：1–5 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`。 - 公开的 `https://` 链接，最多 5 个。创建任务时不会下载或检测。 - 不能与 `images` 同时发送。 **取值有误时** - 超过 5 个链接：`"reference_audios" accepts at most 5 items`
- `reference_videos` (list of string, optional) — 模型用作新视频参考的视频。 **数量**：1–5 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`。 - 公开的 `https://` 链接，最多 5 个。创建任务时网关不会下载、检测或限制它们，因此模型无法使用的片段会在之后导致任务失败（会退款）。 - 不能与 `images` 同时发送。 **取值有误时** - 超过 5 个链接：`"reference_videos" accepts at most 5 items` - 与 `images` 同时使用：`Cannot combine "images" with reference inputs in one task`
- `resolution` (enum, optional, default: 720p) — 输出分辨率。1080p 每秒的价格高于 720p。 **可选值**：`720p`, `1080p` **默认值**：`720p` - 仅限小写。不提供 480p。 **取值有误时** - 取值不在列表中（例如 `480p` 或 `720P`）：`"resolution" must be one of: [720p 1080p]`
  - Allowed values: `720p`, `1080p`
