Face Swap API 调用参考
只换脸，发型、姿势和背景都不动
用一个 PopNow API 密钥，就能在自己的代码里调用 Face Swap。下面列出要填的调用名、这个型号接受的每个输入字段、每次请求花多少积分，以及一段可以直接粘进终端运行的请求。
参数说明直接取自型号的输入 schema，暂时只有英文。

- 出品方

- 1.95 积分 每张图 ($0.0195)
- 一般耗时
- 约 16 秒
1 积分 = 0.01 美元。任务受理时先冻结可能的最高费用，完成后按实际用量结算、向上取整到整积分，多冻的退回；失败的任务不扣积分。想在运行前知道确切数字，先调 POST /api/v1/jobs/quote。

默认 | 1.95 | $0.0195 |
参数
| 字段 | 类型 | 默认值 | 取值范围 | 作用 |
|---|---|---|---|---|
image_url必填 | string | — | — | Target image. The face of the person in this image is the one that gets replaced. |
reference_image_url必填 | string | — | — | Reference face image. The facial features from this image are transferred onto the target. |
face_mapping可选 | array<object> | — | 最多 10 项 | Multi-person swap: which face in the reference image goes onto which face in the target, one entry per face. Faces are numbered from 0 in detection order. Leave it out to swap a single face. |
style可选 | string | realistic | realistic, beautify, lossless | Finish applied to the swapped face: realistic keeps natural skin tone and texture, beautify smooths and brightens the skin, lossless holds on to the most facial detail. |
face_enhance可选 | boolean | false | — | Run a face-enhancement pass on the swapped face for a sharper, more detailed result. |
seed可选 | integer | — | 0 到 2147483647 | Random seed; zero requests a random seed. |
请求示例
这段请求原样就能运行，没写的字段都用默认值。运行前先把密钥放进环境变量 POPNOW_API_KEY。
示例里的 image_url, reference_image_url 用的是 PopNow 的示例素材，换成你自己的公开 HTTPS 链接、上传文件或已保存的素材即可。
curl -X POST "https://api.popnow.ai/api/v1/jobs/createTask?wait=60" \
-H "Authorization: Bearer $POPNOW_API_KEY" \
-H "Content-Type: application/json" \
-H "Idempotency-Key: $(uuidgen)" \
-d '{
"model": "popnow/face-swap-v1/edit",
"input": {
"image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
"reference_image_url": "https://media.popnow.ai/influencer/examples/ava.webp"
}
}'响应里会立刻带回 taskId。之后用 GET /api/v1/jobs/recordInfo 取结果，或者在请求里加上 callBackUrl 等通知。
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=TASK_ID_FROM_CREATE_TASK" \
-H "Authorization: Bearer $POPNOW_API_KEY"
