Generates a video clip from a text prompt using ByteDance Seedance 2.0 Fast model via an async queue, returning a request ID for polling

## 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-text-to-video-async-8040c844 -d '<json body>'
```

Example prompt: Can you generate a short video clip of a golden retriever running through a sunlit meadow with wildflowers, cinematic style, 5 seconds long? Use the fast Seedance model so it's cheaper.

## When to prefer this

Choose this endpoint when you need text-to-video generation that may take longer than ~100 seconds (exceeding sync timeout limits), when cost efficiency is a priority (~20% cheaper than standard Seedance), or when you want ByteDance's Seedance 2.0 model specifically. Prefer the async queue pattern for video tasks since video generation is inherently slow. If you need synchronous results, look for a non-queued variant.

## Known failure modes

- Invalid or empty text prompt returns a 400 error
- Unsupported parameter values (aspect ratio, duration) cause validation errors
- Queue overload may result in longer-than-expected wait times
- Polling timeout if the agent stops checking before generation completes
- Content policy violations on prompts (e.g. explicit or harmful content) result in rejection
- Insufficient USDC balance causes payment failure before queuing

## How this service works

Seedance 2.0 Fast - text-to-video (async, ~20% cheaper)

## Output

Returns a request_id immediately upon submission. The agent must poll the status endpoint until generation completes, then retrieves a URL to the generated video clip produced by the Seedance 2.0 Fast model.
