wan2.7-r2v API
通过 Modelflare 异步视频入口使用精确的 wan2.7-r2v 模型 ID。
使用精确模型 ID wan2.7-r2v。请求中的模型名必须与本页完全一致。
请求参数:duration=5resolution=1080Pratio=16:9参考图片
提示词:One continuous take, no cuts. Keep the glass flowers from the reference exactly as they are and carry them into a new place: a wide city crossing at night in the rain. The whole bed of glass blooms now grows straight out of the wet asphalt across the junction, ringing as the rain strikes them, headlights firing caustics along the road. The camera starts at kerb height among the stems, moves forward through them and rises to look down the length of the crossing. One hard pink key from a shopfront on the left, cold blue signals behind. Real weight and inertia, glass and water, no text.

Section titled “任务查询与下载”提交成功后保存任务 ID。使用 GET /v1/videos/{task_id} 轮询,完成后使用 GET /v1/videos/{task_id}/content 下载;结果地址可能过期,应及时转存。
curl https://modelflare.dev/v1/videos/TASK_ID \ -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY"Wan 通常使用 input 与 parameters;帧引导和 reference media 不能混用。
Wan2.7 R2V 用 reference_image / reference_video 构成参考输入;可在参考媒体上附加 reference_voice。不要与 first_frame / last_frame 工作流混用。

Section titled “错误与失败任务”参数不符合模型契约时,创建接口会返回带 request ID 的 4xx。异步任务也可能在创建成功后进入 failed;轮询响应中的 error_code 和 error_message 才是该任务的最终原因。不要把同一请求改成另一种 JSON 结构重试。
本页只覆盖 Modelflare 的模型生成/编辑调用。搜索或地图增强、声音管理、元素库管理等资源型接口不属于本页的公开调用范围,也不需要作为模型请求字段传入。
