How to Build AI Video Generation Into Your API Pipeline (2026)

Why Video Needs a Different Pipeline

Chat completions return in milliseconds. Image generation returns in seconds. Video generation takes 30 seconds to several minutes. Your pipeline needs async task management -- not simple request-response.

The Three-Stage Pipeline

Task Submission -- Submit prompt + references, get task ID
Status Monitoring -- Poll or webhook for pending -> running -> completed
Result Retrieval -- Download the generated video file

Step 1: Submit a Task

import requests
r = requests.post("https://api.aiapi-pro.com/v1/video/generations",
  headers={"Authorization": "Bearer " + KEY},
  json={"model":"doubao-seedance-2.0","prompt":"Sunset drone shot",
        "resolution":"1080p","duration":8})
task_id = r.json()["id"]  # "cgt-20260714183705-5wkf5"

Step 2: Poll or Webhook

import time
while True:
    r = requests.get(f"https://api.aiapi-pro.com/v1/video/generations/{task_id}",
                     headers={"Authorization": "Bearer " + KEY})
    data = r.json()
    if data["status"] in ("completed","failed"): break
    print(f"Progress: {data.get('progress','processing')}")
    time.sleep(5)
if data["status"]=="completed": print(f"Video: {data['video_url']}")

Multi-Modal: Beyond Text Prompts

Seedance 2.0 accepts reference images, videos, and audio in one call for brand-consistent content:

{"model":"doubao-seedance-2.0",
 "content":[
   {"type":"text","text":"First-person fruit tea commercial"},
   {"type":"image_url","image_url":{"url":"https://cdn.example.com/product.jpg"},"role":"reference_image"},
   {"type":"audio_url","audio_url":{"url":"https://cdn.example.com/bgm.mp3"},"role":"reference_audio"}
 ],"resolution":"1080p","duration":10}

Cost Management Tips

Use Seedance 2.0 Fast for prototyping ($0.054/s at 480p)
Start at 480p for drafts, render finals at higher resolution
Set per-user daily limits to control costs at scale

Frequently Asked Questions

How do I integrate AI video generation into my API?

Use async task submission: POST to /v1/video/generations with your prompt and parameters, then poll the task status endpoint or set up a webhook for completion notification. NovAI provides OpenAI-compatible endpoints for Seedance 2.0.

How long does AI video generation take?

A 10-second 1080p video typically takes 30-60 seconds to generate via Seedance 2.0. The API returns a task ID immediately, and you poll for status until completion.

Can I use webhooks for AI video generation?

Yes, NovAI supports webhook delivery for video generation tasks. When the video is ready, NovAI sends a POST request to your callback URL with the video URL and metadata.
