## 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-grok-imagine-text-to-video-async-via-fal-queue-3b237e0b -d '<json body>'
```

Example prompt: Generate a short video of a futuristic city at night with neon lights reflecting off rain-soaked streets using Grok Imagine — submit it async and give me the request ID so I can check back when it's done.

## When to prefer this

Choose this endpoint when you need to generate video from a text prompt using xAI's Grok Imagine model and the generation time may exceed synchronous timeout limits (~100s). This async queue variant is ideal for agents that can submit a job and poll for results later. Prefer this over sync alternatives when video quality from Grok Imagine is specifically required or when building workflows that handle long-running media generation tasks.

## Known failure modes

- Invalid or empty prompt returns a 400 error
- Prompt violates content policy and is rejected
- Queue is overloaded, causing delayed processing or timeout
- Invalid authentication or payment credentials return 401/402
- Polling with an expired or invalid request_id returns not-found error
- Generation fails server-side, returning an error status on poll

## How this service works

Grok Imagine text-to-video (async)

## Output

Returns a request_id immediately upon job submission. The agent must poll a separate status endpoint using this ID to retrieve the final video URL once generation is complete. The video is rendered asynchronously, so the result is not available in the initial response.
