How do you switch from the Runway API?
- Create an API key in the KreatorFlow developer console and top up tokens.
- Send POST /v1/videos with a model, prompt, duration, resolution and aspect ratio; the response quotes the job's cost before it runs.
- Receive the result by signed webhook, or poll GET /v1/jobs/{id}, then download the file.
- Pass reference images, clips or audio by URL or upload; video edits and characters have their own endpoints.
Who runs the models on KreatorFlow?
KreatorFlow is an official partner of BytePlus, a ByteDance company. Built on BytePlus, a ByteDance company. The API serves ByteDance's Seedance video models and Seedream image models.
Is there volume pricing?
The more you top up, the less Seedance video costs. Your tier comes from the token top-ups you paid for in the last 30 days. It lowers the per-second price of Seedance video and raises your video request limit, automatically, with no contract and no sales call. If your top-ups drop, the tier moves back down.
| Tier | Paid top-ups, last 30 days | Seedance video price | Video requests / minute | Reached in one top-up |
|---|---|---|---|---|
| Standard | Any | List price | 20 | – |
| Scale | $1,000+ | up to 5% off | 60 | Volume pack ($1,250) |
| Growth | $2,500+ | up to 7.5% off | 120 | Volume+ pack ($2,500) |
| Enterprise | $5,000+ | up to 10% off | 300 | Enterprise pack ($5,000) |
Every job's quote shows your price before it runs; a few low-priced settings get a smaller discount. Smaller top-ups add up toward a tier too. Price comparisons on this site use list prices unless a price is marked as at volume. Need more volume? Custom pricing for committed monthly spend: email harry@kreatorflow.ai.
How we compared

Seedance API price per second on KreatorFlow
Seedance 2.0 and 2.5 at 720p and above on the KreatorFlow API: price per second, tokens per 5-second clip, and clips per prepaid top-up.
| Model · resolution | Tokens | 5 s clip | List rate per second | $20 top-up · 400 tokens | $50 top-up · 1,000 tokens | $100 top-up · 2,000 tokens | $250 top-up · 5,000 tokens |
|---|---|---|---|---|---|---|---|
| Seedance 2.0 · 720p | 11/5s | $0.55 | $0.110/s | 36 | 90 | 181 | 454 |
| Seedance 2.0 · 1080p | 24/5s | $1.20 | $0.240/s | 16 | 41 | 83 | 208 |
| Seedance 2.0 · 4K | 58/5s | $2.90 | $0.580/s | 6 | 17 | 34 | 86 |
| Seedance 2.5 · 720p | 21/5s | $1.05 | $0.207/s | 19 | 47 | 95 | 238 |
| Seedance 2.5 · 1080p | 45/5s | $2.25 | $0.444/s | 8 | 22 | 44 | 111 |
| Seedance 2.5 · 4K | 100/5s | $5.00 | $0.999/s | 4 | 10 | 20 | 50 |
Seedance 2.0 and 2.5, 720p and above. List rate per second is the rate card price; a clip is billed at that rate and its total rounded up to whole tokens ($0.05), which is why a 5-second clip can cost a cent or two more than rate x 5. Top-up columns: 5-second clips each top-up covers, without a video input. A 10-second clip uses about twice the tokens.
