Why NanoAPI
Easier to make, better to watch, billed by the second or by the image.
- 01
Pay for what you make, nothing hidden
Genjutsu bills your source video’s seconds × resolution, with no extra fee for the reference video; Kling and Seedance bill the output length; image models bill each image you get. Failed runs are free.
- 02
Viral remakes in one click
Pick a viral video, add one photo and get your version. No template tweaking.
- 03
Better than generic video APIs
Fine-tuned from Seedance 2.5 for motion transfer, so people, moves and camera stay true to the original.
- One key for every model
- One balance, never expires
- Failed runs are free
- Signed webhooks
- Developer console
Pay by the second or by the image
No subscription. Same prices in the playground and on the API.

FAQ
Questions, answered
Can’t find what you need? Write to us.
01What is NanoAPI?
One API for creative AI models. You use one API key and one prepaid balance for every model.
02How is Genjutsu 1.0 different from Seedance 2.5?
Genjutsu 1.0 is fine-tuned from Seedance 2.5 for motion transfer: you only need a viral video and one photo, and there’s no extra fee for the reference video’s length. For text to video, references, video edit or extension, call Seedance 2.5 itself with the same API key.
03Which models are available?
Video models Genjutsu 1.0, Genjutsu Lite 1.0, Kling 4.0 and Seedance 2.5, and image models Nano Banana 2.1, GPT Image 2.5 and Seedream 5.0 Pro are live. Audio and more models are on the way, on the same key and balance.
04How does billing work?
Video models bill by the second: Genjutsu models bill the source video’s seconds × the price of the resolution, with no extra fee for the reference video; Kling 4.0 and Seedance 2.5 bill the output length you ask for × the price of the mode and resolution. Image models bill per image: the price of the resolution (and quality for GPT Image 2.5) × the number of images you get. The cost is reserved when you submit and charged when the task succeeds. Failed tasks are free.
05Do I need a subscription?
No. Top up $10, $50, $500 or $1,200 whenever you need; $500 comes with a 5% bonus ($525 credited) and $1,200 with 10% ($1,320 credited). Your balance never expires.
06Can I try a model without code?
Yes. Every model has a playground on the website, with the same prices and balance as the API.
07How do I get the results?
Tasks are asynchronous. Pass a webhook_url when you create one, or poll the task. Genjutsu tasks usually take 5–10 minutes, Kling 4.0 1–5 minutes and Seedance 2.5 4–6 minutes; images take from about 15 seconds to a few minutes.
