参数
这些字段来自我们校验每个请求所用的同一份 Schema。没列出的字段会被拒绝。
promptstring必填What happens after the first frame, or between the first and last frame.
image_urlstring必填作为起点的那张图。
last_image_urlstring可选可选的结尾画面,让视频正好停在你想要的地方。
resolutionstring可选影响价格输出尺寸。越大越清晰,价格也越高。
duration_secondsinteger可选影响价格视频时长,按秒计费。
generate_audioboolean可选影响价格加上和画面匹配的声音:人声、环境音和音效。
shot_typestring可选single keeps one continuous shot; multi lets the model cut the clip into several shots.
seedinteger可选用同一个数字,结果就能复现。

响应、轮询与回调
所有模型的用法都一样:先建任务,再轮询,或者等回调。
先报价
curl -X POST https://api.popnow.ai/api/v1/jobs/quote \
-H "Authorization: Bearer $POPNOW_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "pixverse/v6/image-to-video",
"input": {
"prompt": "A slow aerial shot drifting over a misty pine forest at sunrise",
"image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
"resolution": "720p",
"duration_seconds": 5,
"shot_type": "single"
}
}'运行前,将相同请求体发送到 POST /jobs/quote,可查看预计费用和最高费用,单位为美元。报价不会运行任务或扣款。
已受理
HTTP/1.1 202 Accepted
{
"code": 200,
"msg": "success",
"data": {
"taskId": "task_01k3m8x9q2z4v7n5p6r8s0t1w3",
"state": "queued"
},
"request_id": "req_example_create"
}HTTP 202 表示已受理:最高美元金额已冻结,等待结算。 任务受理时,从 API 余额中冻结报价的最高金额;完成后按实际用量结算,实扣不超过冻结额,并释放剩余金额。任务失败则释放冻结额。
查询状态
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
-H "Authorization: Bearer $POPNOW_API_KEY"每隔几秒查一次并逐步拉长间隔,state 变成 succeeded、failed、canceled 或 expired 时停止。
完成的任务

校验回调
import { createHash, createHmac, timingSafeEqual } from "node:crypto";
import express from "express";
const app = express();
// express.raw keeps the exact bytes that were signed; express.json would not match.
app.post("/hooks/popnow", express.raw({ type: "application/json" }), (req, res) => {
const timestamp = req.header("X-Webhook-Timestamp");
const signature = req.header("X-Webhook-Signature") ?? "";
const body = JSON.parse(req.body.toString("utf8"));
const taskId = body.data?.taskId ?? body.task_id;
const digest = createHash("sha256").update(req.body).digest("hex");
const expected = createHmac("sha256", process.env.POPNOW_WEBHOOK_SECRET)
.update(`${taskId}.${timestamp}.${digest}`)
.digest("base64");
const ok = expected.length === signature.length && timingSafeEqual(Buffer.from(expected), Buffer.from(signature));
// Check the signature first, then reject anything older than five minutes.
if (!ok || Math.abs(Date.now() / 1000 - Number(timestamp)) > 300) return res.status(401).end();
res.status(200).end(); // answer fast, then fetch the task and store its files
});设置了 callBackUrl,我们会把完成的任务发给你。先用原始请求体校验签名,再信任它。
上传本地文件
curl -X POST https://api.popnow.ai/api/v1/common/upload-url \
-H "Authorization: Bearer $POPNOW_API_KEY" \
-H "Content-Type: application/json" \
-d '{"contentType": "image/png", "bytes": 482113}'
# PUT the file bytes to data.uploadUrl with every header in data.headers, then commit it:
curl -X POST https://api.popnow.ai/api/v1/files/$FILE_ID/commit \
-H "Authorization: Bearer $POPNOW_API_KEY"
# The commit returns a popnow://f/... reference. Put it in any image, video or
# audio field of the task input instead of a public https URL.公开的 https 链接可以直接用。本地文件要先经过 upload-url 和 commit。
