任务状态与回调

异步任务请保存返回的 taskId。调用 GET /api/v1/jobs/recordInfo?taskId=... 查询，或在创建时设置 callBackUrl。只有任务所属账号可以查询任务或基于任务创建派生资源。

超时可能表示请求已经受理。请在控制台查看原请求，不要自动新建任务。回调可能重试并重复到达，请使用 X-VezAPI-Event-Id 去重。

文件、日志与计费

生成媒体通常随上游保留 14 天，上传文件在 24 小时后失效。请在过期前保存所需文件。VezAPI 仅流式转发已登记资源，不提供永久作品库。请求日志保留两个自然月。

调用前预留积分，最终按实际优惠扣分 1:1 结算。用量不明时暂停新付费请求。若保护其他任务预留后余额不足以结算，会保留待结算记录，补足余额后再扣费；模型用量不会将钱包扣成负数。按时长计价的输入文件由服务端读取时长，读取失败时不提交模型任务。
