Seedance 1.5 Pro on PixelAPI — AI Video Generation (Text & Image to Video) in Under 2 Minutes

#ai #video #api #webdev

If you've used AI video generation APIs, you know the drill — submit a prompt, wait 10-15 minutes, hope for the best. We've been there too with our WAN 2.1 endpoint.

Today we're adding Seedance 1.5 Pro (by ByteDance) as a premium option. Same API, two choices now. And it supports both text-to-video and image-to-video.

Best for	Budget batches	Fast iteration, client work

Text-to-Video (API)

import requests

response = requests.post(
    "https://api.pixelapi.dev/v1/video/generate",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={
        "prompt": "A drone shot flying over a neon city at sunset",
        "model": "seedance-1.5"
    }
)
print(response.json())
# {"generation_id": "abc-123", "status": "processing", "credits_used": 250}

Image-to-Video (NEW)

Upload a reference image and describe how you want it to move:

import requests

response = requests.post(
    "https://api.pixelapi.dev/v1/seedance/generate",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    files={"image": open("my_photo.jpg", "rb")},
    data={"prompt": "Camera slowly zooms in, the subject smiles and waves"}
)
print(response.json())
# {"generation_id": "def-456", "status": "processing", "credits_used": 250}

This is useful when you want to animate a product photo, bring a still portrait to life, or create video from existing artwork.

Poll for Completion

status = requests.get(
    f"https://api.pixelapi.dev/v1/seedance/{generation_id}",
    headers={"Authorization": "Bearer YOUR_API_KEY"}
).json()

if status["status"] == "completed":
    print(status["output_url"])  # Your video URL

Why Two Models?

Not every use case needs premium speed. If you're batch-processing 100 videos overnight, WAN 2.1 at $0.135 each saves real money. But if you're iterating on a client project, need image-to-video, or want results in 2 minutes instead of 15, Seedance pays for itself.

Pricing Context

Seedance 1.5 Pro via other providers:

BytePlus direct: ~$0.13/video (but you build the integration yourself)
