认证

string

必填

所有接口均需要使用 Bearer Token 进行认证。获取 API Key：访问 API Key 管理页面获取您的 API Key。使用时在请求头中添加：

Authorization: Bearer YOUR_API_KEY

请求参数

string

必填

视频生成模型名称，固定为 Omni-Flash-Ext。

string

必填

视频内容描述。建议详细描述场景、人物、动作、环境、镜头运动、画面风格和音频提示。示例："a girl is dancing happily in a sunny garden"

integer

默认值:"6"

视频时长，单位为秒。仅支持：4、6、8、10。

传入 5、7 等其他时长会返回 invalid_duration 错误。

上传参考视频时不需要传入 duration。duration 与 video_urls 不可以同时传入。

string

默认值:"720p"

视频分辨率，不区分大小写。可选值：

720p
1080p
4k

传入其他分辨率会返回 invalid_resolution 错误。

string

默认值:"16:9"

视频宽高比，用于控制横屏或竖屏。常用值：

16:9 - 横屏
9:16 - 竖屏

默认值：16:9

string

兼容字段，含义与 aspect_ratio 相同。若同时传入，建议保持与 aspect_ratio 一致。

string

生成类型，用于指定图片的使用方式。可选值：

frame - 首帧模式。image_urls 只可以上传 1 张图片，作为视频首帧。
reference - 参考模式。image_urls 可以上传 1 张或 3 张图片，作为参考图。

当 generation_type 为 frame 时，image_urls 仅支持 1 张图片；传入其他数量会返回 unsupported_image_count 错误。

array<url>

参考图片 URL 数组。可不传、传 1 张或传 3 张，具体数量取决于 generation_type：

不传或空数组：文生视频
1 张图片：单图生视频
3 张图片：参考图融合（仅在 generation_type 为 reference 时支持）

与 generation_type 的关系：

generation_type 为 frame：只可以上传 1 张图片。
generation_type 为 reference：可以上传 1 张或 3 张图片。

只支持公网可访问的图片 URL。

不支持 2 张图的首尾帧模式。传入 2 张图片会返回 unsupported_image_count 错误。4 张及以上未实测验证，不建议使用。

array<url>

参考视频 URL 数组。可不传或传 1 个参考视频。只支持公网可访问的 HTTP/HTTPS 视频 URL。可与 image_urls 同时传入，图片作为身份或构图参考，视频作为动态参考。

Omni-Flash-Ext 仅支持 0 或 1 个参考视频。传入 2 个及以上视频会返回 unsupported_video_count 错误。

传入 video_urls 时不需要传入 duration。video_urls 与 duration 不可以同时传入。

响应

integer

响应状态码，成功时为 200。

array

返回任务数组。

显示数组元素

string

任务初始状态，提交成功时为 submitted。

string

任务唯一标识符，用于查询任务状态和结果。

查询任务结果

视频生成为异步任务。提交后会返回 task_id，使用获取任务状态接口查询生成进度和结果。

cURL

curl --request GET \
  --url https://api.apimart.ai/v1/tasks/task_01KS1H7ZYSJWH1N779S2FSHTKA \
  --header 'Authorization: Bearer <token>'

建议提交后等待 5-10 秒再开始查询，后续每 5-10 秒轮询一次。单个任务通常约 3-5 分钟完成。

错误码

HTTP	错误类型	含义	处理建议
400	`invalid_request_error`	`model` 不是 `Omni-Flash-Ext`、`prompt` 为空或 JSON 格式错误	检查请求体
400	`invalid_duration`	`duration` 不是 `4`、`6`、`8` 或 `10`	改成支持的时长
400	`invalid_resolution`	`resolution` 不是 `720p`、`1080p` 或 `4k`	改成支持的分辨率
400	`unsupported_image_count`	`image_urls` 数量不受支持，常见于传入 2 张图	改成 0、1 或 3 张图片
400	`unsupported_video_count`	`video_urls` 数量不受支持，常见于传入 2 个及以上视频	改成 0 或 1 个参考视频
401	`authentication_error`	Token 无效	检查 Bearer Token
402	`payment_required`	账户余额不足	充值后重试
429	`rate_limit_error`	触发限流	降低并发或稍后重试

任务失败时，任务查询接口会在 data.error 中返回失败原因。常见原因包括上游配额暂时耗尽、内容审核未通过或上游超时。
