接口 ​

POST /jobs/createTask

完整 URL: https://ai.modelfold.online/v1/jobs/createTask

鉴权:所有请求都需要 Authorization: Bearer <API_KEY> 请求头。

基于 Seedream 先进 AI 模型的高质量写实风格图像生成

查询任务状态 ​

提交任务后,可通过统一的查询端点查看任务进度并获取生成结果:

TIP

生产环境中,建议使用 callBackUrl 参数接收生成完成的自动通知,而非轮询状态端点。

请求参数 ​

请求体 (application/json) ​

参数类型必填说明
modelstring是用于生成的模型名称。必填字段。
- 此端点必须使用 seedream/5-lite-text-to-image 默认值:"seedream/5-lite-text-to-image"。 可选值:seedream/5-lite-text-to-image。 示例:seedream/5-lite-text-to-image。
callBackUrlstring否接收生成任务完成更新的 URL。可选但建议在生产环境中使用。
- 当生成完成时,系统将向此 URL POST 任务状态和结果
- 回调包含生成的内容 URL 和任务信息
- 您的回调端点应接受包含结果的 JSON 负载的 POST 请求
- 或者,使用获取任务详情端点轮询任务状态
- 为确保回调安全性,请参阅 Webhook 校验指南 了解签名验证实现方法 示例:https://your-domain.com/api/callback。
