Create and submit a video generation task. The response contains a generation ID.
Poll the retrieval endpoint with that generation ID until the status is completed.

Body

modelstring · enumRequiredPossible values:

providerstringOptional

Provider routing override. bytedance runs native ByteDance with no fallback; fal runs the fal.ai mirror; auto (default) uses the ByteDance -> fal.ai fallback chain. Case-insensitive.

image_urlsstring · uri[] · min: 1 · max: 9Optional

Reference images to guide video generation. Refer to them in the prompt as @Image1, @Image2, etc.

audio_urlsstring · uri[] · min: 1 · max: 3Optional

Reference audio to guide video generation. Refer to them in the prompt as @Audio1, @Audio2, etc. Supported formats: MP3, WAV. Up to 3 files, combined duration must not exceed 15 seconds. If audio is provided, at least one reference image (image_urls) or video (video_urls) is required.

video_urlsstring · uri[] · min: 1 · max: 3Optional

Reference videos to guide video generation. Refer to them in the prompt as @Video1, @Video2, etc. Supported formats: MP4, MOV. Each video must be between ~480p (640x640) and ~720p (834x1112) in resolution.

aspect_ratiostring · enumOptional

Default: 720pPossible values:

durationinteger · enumOptional

The length of the output video in seconds.

Default: 5Possible values:

generate_audiobooleanOptional

Whether to generate audio for the video.

Default: true

seedintegerOptional

Varying the seed integer is a way to get different results for the same other request parameters. Using the same value for an identical request will produce similar results. If unspecified, a random number is chosen.

watermarkbooleanOptional

Whether the video contains a watermark.

Default: false

Code Example

The examples submit a generation task and poll every 15 seconds until the final result is available.

import requests
import time

api_key = "<YOUR_AIMLAPI_KEY>"
url = "https://api.aimlapi.com/v2/video/generations"
headers = {
    "Authorization": f"Bearer {api_key}",
    "Content-Type": "application/json",
}

generation = requests.post(url, headers=headers, json={'model': 'bytedance/dreamina-seedance-2-0-mini', 'prompt': 'Describe what you want the model to generate.', 'image_url': 'https://example.com/input.jpg', 'duration': '5'})
generation.raise_for_status()
generation_id = generation.json()["id"]

while True:
    result = requests.get(
        url,
        headers=headers,
        params={"generation_id": generation_id},
    )
    result.raise_for_status()
    data = result.json()
    if data.get("status") not in ("queued", "generating"):
        print(data)
        break
    time.sleep(15)

const apiKey = "<YOUR_AIMLAPI_KEY>";
const url = "https://api.aimlapi.com/v2/video/generations";
const headers = {
  "Authorization": `Bearer ${apiKey}`,
  "Content-Type": "application/json",
};

const generation = await fetch(url, {
  method: "POST",
  headers,
  body: JSON.stringify({
  "model": "bytedance/dreamina-seedance-2-0-mini",
  "prompt": "Describe what you want the model to generate.",

});
const { id: generationId } = await generation.json();

while (true) {
  const response = await fetch(
    `${url}?generation_id=${encodeURIComponent(generationId)}`,
    { headers },
  );
  const data = await response.json();
  if (!["queued", "generating"].includes(data.status)) {
    console.log(data);
    break;
  }
  await new Promise((resolve) => setTimeout(resolve, 15000));
