iApp launches Seedance 2.0 — Generate AI videos with one Thai-billed API key

We're launching Seedance 2.0 video generation as the newest API on the iApp platform. From today, your existing iApp API key can submit a text prompt — optionally with a reference image, video, or audio clip — and get back a fully-rendered MP4 in 30 seconds to 4 minutes. No second account, no foreign-currency invoice, no scraping together a bespoke pipeline.

This is a reseller integration of BytePlus Ark's Dreamina Seedance 2.0 family. We forward your request to the BytePlus Singapore region, attach our own auth, and bill you in iApp credits (IC) the same way you already pay for OCR, eKYC, LLM, and Speech.

What you get

• Two model tiers, one endpoint. dreamina-seedance-2-0-fast-260128 for cheap drafts (up to 720p). dreamina-seedance-2-0-260128 for full-quality 1080p hero shots. Switch via the model field per request.
• All input modalities. Text-to-video, image-to-video (reference_image / first_frame / last_frame roles), video-to-video editing (reference_video), and audio-driven generation (reference_audio).
• Native audio output. Toggle generate_audio: true and Seedance composes a matching soundtrack with the video.
• Singapore region. ~10–30 ms gateway overhead from Thailand. The same hardware that BytePlus direct customers use.
• Per-token pricing. You pay for actual GPU work — measured by usage.completion_tokens returned with each successful job. Failed renders cost zero.

Try it without writing any code:

Pricing — billed per output token, with a small margin over BytePlus

Model	Resolution	Input has video?	iApp rate (IC / 1K tokens)
Seedance 2.0	480p / 720p	no	0.302
Seedance 2.0	480p / 720p	yes	0.186
Seedance 2.0	1080p	no	0.333
Seedance 2.0	1080p	yes	0.203
Seedance 2.0 Fast	480p / 720p	no	0.242
Seedance 2.0 Fast	480p / 720p	yes	0.143

Concrete examples (text-only prompt, 16:9, 24 fps, 5 s clip):

• 5-second 480p draft on Fast model ≈ 15 IC (~₿15)
• 5-second 720p reel on Fast model ≈ 33 IC (~₿33)
• 5-second 1080p hero shot on full model ≈ 101 IC (~₿101)

Billing reads the usage.completion_tokens field from BytePlus, applies the matching tier rate, and rounds up to the nearest 1K tokens. You are only charged for successful generations — content-moderation rejections, internal failures, and timeouts cost zero.

60-second quickstart (Python)

import os, time, requests

API = "https://api.iapp.co.th/v3/store/video/seedance/tasks"
H = {"apikey": os.environ["IAPP_API_KEY"], "Content-Type": "application/json"}

# 1. Submit
task_id = requests.post(API, headers=H, json={
    "model": "dreamina-seedance-2-0-fast-260128",
    "content": [{"type": "text", "text": "A cat surfs a wave at sunset, cinematic"}],
    "duration": 5, "ratio": "16:9", "resolution": "720p", "generate_audio": True,
}).json()["id"]

# 2. Poll until ready
while True:
    r = requests.get(f"{API}/{task_id}", headers=H).json()
    if r["status"] == "succeeded":
        url = r["content"]["video_url"]; break
    time.sleep(5)

# 3. Download (link expires in ~24h)
open("output.mp4", "wb").write(requests.get(url).content)

That's the entire integration. The full reference, including all body fields and code samples in cURL / Node.js / Go, lives in the Seedance 2.0 docs.

Premium-only: paid accounts unlock it

A single 1080p render can run 60–100 IC, far above any other API on the platform. To prevent a free signup from accidentally burning hundreds of dollars of GPU time, Seedance is restricted to accounts that have purchased any IC package at least once.

If you've never topped up before, the smallest package unlocks every premium API on the platform — including Seedance — and the IC you buy never expires. Buy 1,000 IC to get started.

What's next

• We're tracking adoption to decide whether to add the upcoming Seedance 1.5 Pro (audio-included offline inference) and Seedance 1.0 Pro (cheaper for static-camera scenes) to the same model field.
• A webhook for task completion is planned for Q3 2026 so you can stop polling.
• Batch mode at half price is on the roadmap for jobs that don't need real-time turnaround.
