# x402.agentutility.ai Text-to-Video (Seedance)

> x402.agentutility.ai Text-to-Video (Seedance) is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

Generates a short MP4 video clip from a text prompt using fal.ai Bytedance Seedance, with configurable duration, aspect ratio, and resolution, returning a hosted video URL.

## 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 x402-agentutility-ai-text-to-video-seedance-88af7b59 -d '<json body>'
```

Example prompt: Generate a 5-second 16:9 video of a golden retriever running through a field of sunflowers in slow motion — use AI video generation and give me the MP4 link when it's done.

## When to prefer this

Choose this endpoint when you need to generate short AI video clips from text descriptions using the Bytedance Seedance model specifically, with pay-per-call USDC pricing via x402 and no subscription required. Prefer it for autonomous agent workflows needing programmatic, on-demand video generation with configurable aspect ratios (including vertical 9:16 for social media) and resolutions. It is particularly suited for agents that need a simple REST call returning a ready-to-use hosted MP4 URL without managing fal.ai credentials directly.

## Known failure modes

- Invalid or missing prompt returns a 400 or validation error
- Unsupported aspect ratio or resolution value causes request rejection
- fal.ai backend timeout or generation failure results in an error response
- Payment failure (insufficient USDC) blocks the request via x402 protocol
- Model override referencing a non-existent fal.ai model returns an upstream error

## How this service works

Generates video from a text prompt via fal.ai Bytedance Seedance. Duration, aspect ratio, and resolution are configurable. Returns a hosted MP4 URL plus fal request id and seed. Use it for AI video, Seedance generation, generative video, and cinematic clips from a prompt.

## Output

A JSON object containing a hosted MP4 video URL (video_url), the fal.ai request ID (fal_request_id), the random seed used (seed), the model name, the original prompt, and the configured duration, resolution, and aspect ratio. The video is immediately streamable from the returned URL.
