## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability seedance-2-5-video-five-seconds-with-audio-4950ad62 -d '<json body>'
```

Example prompt: Generate a 5-second 720p landscape video of a glowing candle flickering on a wooden desk in a dark room, with soft crackling ambient sound, using Seedance 2.5.

## When to prefer this

Choose this endpoint when you need a short, ready-to-use 5-second video clip with native audio generated from a text prompt, especially when audio is a requirement alongside visuals. Prefer this over image generation when motion and sound are needed. Best suited for social media clips, product teasers, ambient footage, or concept previews where a 720p MP4 with audio suffices. Not suitable for longer videos, image-only output, or audio-only generation.

## Known failure modes

- HTTP 202 returned before video is ready — agent must retry with same payment and input
- Prompt too short (below 1 character) or too long (above 2000 characters) triggers validation error
- Unsupported aspect_ratio value other than '16:9' or '9:16' causes rejection
- Payment not included or insufficient USDC (below 1.63) results in payment failure
- Prompt content policy violation by ByteDance/BlockRun may reject generation
- Service unavailability from upstream BlockRun or ByteDance infrastructure causes failure

## How this service works

Seedance 2.5 Video: Five Seconds with Audio: Generate a five-second 720p video with native audio using ByteDance Seedance 2.5 via BlockRun. Choose landscape or portrait. Returns a hosted MP4 URL and metadata. Prompt leaves this PC for those providers. Async: repeat the same payment and input after HTTP 202. Text-to-video only. 1.63 USDC includes one five-second 720p clip with audio.

## Output

Returns an HTTP 202 with a hosted MP4 URL and associated metadata for a five-second 720p video clip that includes natively generated audio. On async retry (repeat same payment and input after 202), the final MP4 download URL and video metadata are delivered. The clip reflects the text prompt in either landscape (16:9) or portrait (9:16) orientation.
