模型名稱ideogram/vector-1/edit
端點POST https://api.popnow.ai/api/v1/jobs/createTask
# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
curl -X POST https://api.popnow.ai/api/v1/jobs/createTask \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "ideogram/vector-1/edit",
  "input": {
    "image_url": "https://media.popnow.ai/influencer/examples/marco.webp",

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.

input 依下方的 Schema 產生,原樣就能通過驗證。把提示詞和連結換成你自己的即可。

參數

這些欄位與請求驗證使用同一份 Schema。未列出的欄位無法通過驗證。

  • image_urlstring必填

    作為起點的那張圖。

    範圍
    字元數: 1 – … · image/jpeg, image/png, image/webp, image/gif · ≤ 50 MB
  • detail_levelstring選填

    選 detailed 保留更細的形狀,simple 把形狀合併成較少、較大的區塊。兩者價格相同。

    預設值
    "detailed"
    可用值
    "detailed""simple"
原始 JSON Schema
{
  "additionalProperties": false,
  "properties": {
    "detail_level": {
      "default": "detailed",
      "description": "detailed keeps finer shapes; simple merges them into fewer, larger shapes. Both cost the same.",
      "enum": [
        "detailed",
        "simple"
      ],
      "type": "string"
    },
    "image_url": {
      "contentMediaType": [
        "image/jpeg",
        "image/png",
        "image/webp",
        "image/gif"
      ],
      "description": "The picture to turn into an SVG: JPEG, PNG or WebP, up to 50 MB.",
      "minLength": 1,
      "type": "string"
    }
  },
  "required": [
    "image_url"
  ],
  "type": "object"
}

回應、輪詢與回呼

所有模型採用相同流程:建立任務後輪詢狀態,或透過回呼接收結果。

先報價

cURL
curl -X POST https://api.popnow.ai/api/v1/jobs/quote \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "ideogram/vector-1/edit",
  "input": {
    "image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
    "detail_level": "detailed"
  }
}'

執行前,將相同請求內容傳送至 POST /jobs/quote,即可查看預估費用與最高費用,單位為美元。報價不會執行任務或扣款。

已受理

HTTP
HTTP/1.1 202 Accepted

{
  "code": 200,
  "msg": "success",
  "data": {
    "taskId": "task_01k3m8x9q2z4v7n5p6r8s0t1w3",
    "state": "queued"
  },
  "request_id": "req_example_create"
}

HTTP 202 表示任務已受理。我們會從 API 餘額中保留報價的最高金額,完成後按實際用量結算,實際扣款不超過保留金額,並釋放剩餘金額;任務失敗則全額釋放保留金額。

查詢狀態

cURL
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

每隔幾秒查詢一次並逐步拉長間隔,state 變成 succeeded、failed、canceled 或 expired 時停止。

完成的任務

JSON
{
  "code": 200,
  "msg": "success",
  "data": {
    "taskId": "task_01k3m8x9q2z4v7n5p6r8s0t1w3",
    "model": "ideogram/vector-1/edit",
    "state": "succeeded",
    "output": {
      "assets": [
        {
          "url": "https://cdn.popnow.ai/tasks/task_01k3m8x9q2z4v7n5p6r8s0t1w3/output.png?signature=FROM_RESPONSE",
          "expiresAt": "2026-10-17T12:20:00Z",
          "mime": "image/png",
          "width": 1024,
          "height": 1024
        }
      ]
    },
    "settled": true
  },
  "request_id": "req_example_record"
}

請在 expiresAt 之前從 url 下載。之後需要新連結,請呼叫 POST /common/download-url。

驗證回呼

Node.js
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
});

設定 callBackUrl 後,我們會傳送已完成任務的資訊。請先使用原始請求內容驗證簽章,再處理回呼內容。

上傳本機檔案

cURL
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.

公開的 https 連結可以直接用。本機檔案要先經過 upload-url 和 commit。
