Seedance 2.0 API pricing: from $0.066 a second, 480p to 4K

Seedance 2.0 is ByteDance's video model: text, images, reference videos and audio in, a 4 to 15 second clip with sound out, from 480p up to 4K. On aisplice it costs $0.066 per second at 480p and $0.142 at 720p, so a 5-second 720p clip is $0.71. Below are the full price list and requests you can copy.

Price per second

You pay for each second of video you get back, by resolution. Generated sound is included.

• Reference videos are billed on top for their own seconds: $0.04 (480p) to $0.444 (4K) per second.
• A failed task is refunded automatically, so you only pay for clips you get.
• Pay as you go from your balance; there is no subscription and no minimum.

Fast and Mini

Both take the same requests as Seedance 2.0 and stop at 720p. Use them for drafts and volume; switch the model name to render the final cut with the full model.

Text to video

curl https://www.aisplice.store/v1/videos \
  -H "Authorization: Bearer sk-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "doubao-seedance-2.0", "prompt": "A drone shot of a lighthouse at dawn, waves breaking on the rocks", "duration": 5, "resolution": "720p", "size": "16:9"}'
# → {"task_id": "task_xxx", "status": "queued"}

Image to video, first and last frames

Put up to 9 public image URLs in images as references. For a clip that starts and ends on exact frames, send exactly one image in images as the first frame and the last frame in image_tail.

curl https://www.aisplice.store/v1/videos \
  -H "Authorization: Bearer sk-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "doubao-seedance-2.0", "prompt": "The camera slowly pushes in", "images": ["https://example.com/first.jpg"], "image_tail": "https://example.com/last.jpg", "duration": 5}'

Reference videos and audio

• videos: up to 3 public URLs, 1.8 to 15.2 seconds each. The model learns motion, composition and subject from them; their pixels are not copied.
• audios: up to 3 public URLs, 15 seconds in total, together with at least one reference image or video.
• metadata.generate_audio (default true), metadata.seed and metadata.return_last_frame, which returns the clip's last frame as last_frame_url so you can chain clips.

Get the video

Check the task until its status is completed or failed, then download the file. Statuses on the way are queued and in_progress. To be called instead of checking, pass webhook_url when you submit.

import time, requests

BASE = "https://www.aisplice.store"
H = {"Authorization": "Bearer sk-YOUR_KEY"}

task = requests.post(f"https://www.aisplice.store/v1/videos", headers=H, json={
    "model": "doubao-seedance-2.0",
    "prompt": "A drone shot of a lighthouse at dawn, waves breaking on the rocks",
    "duration": 5, "resolution": "720p", "size": "16:9",
}).json()

while True:
    status = requests.get(f"https://www.aisplice.store/v1/videos/{task['task_id']}", headers=H).json()["status"]
    if status in ("completed", "failed"):
        break
    time.sleep(5)

video = requests.get(f"https://www.aisplice.store/v1/videos/{task['task_id']}/content", headers=H)
open("out.mp4", "wb").write(video.content)
