## 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 fal-ai-queue-seedance-2-0-fast-reference-to-video-async-afd85283 -d '<json body>'
```

Example prompt: Animate this product photo into a 5-second video clip — use the image at https://example.com/product.jpg as the reference and make it show a slow cinematic pan; queue it async with Seedance 2.0 Fast since I don't mind waiting a bit for the lower price.

## When to prefer this

Choose this endpoint when you need video generation from a reference image or video using ByteDance Seedance 2.0 Fast and can tolerate async delivery (polling for results) in exchange for ~20% cost savings versus the synchronous variant. Especially cost-effective when using a video as the reference input (0.6x rate). Prefer over the sync fal.run variant when generation may exceed ~100 seconds or when budget optimization matters. Use the non-Fast Seedance 2.0 reference-to-video if you need higher quality over speed.

## Known failure modes

- Invalid or inaccessible reference image/video URL returns an error
- Unsupported media format for the reference input
- Queue timeout or processing failure results in a failed status on polling
- Rate limit exceeded on submission
- Prompt or reference content violates content policy, resulting in rejection
- Missing required parameters (reference URL or prompt) cause a 422 validation error

## How this service works

Seedance 2.0 Fast - reference-to-video (async, ~20% cheaper; 0.6x rate when video reference)

## Output

Returns a request_id immediately upon submission; the agent can poll the fal.ai queue for status and, once complete, retrieves a URL pointing to the generated video clip produced from the reference image or video input.
