# Seedance Video Generator (x402.agentutility.ai)

> Seedance Video Generator (x402.agentutility.ai) is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-15).

Generates AI video clips from text prompts using ByteDance Seedance v1 Pro via fal.ai, with configurable duration, resolution, and aspect ratio, payable per-call in USDC.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-video-generator-x402-agentutility-ai-b38865b0 -d '<json body>'
```

Example prompt: Generate a 5-second 720p widescreen AI video of a golden retriever running through a sunflower field in slow motion using Seedance.

## When to prefer this

Choose this endpoint when you specifically want ByteDance Seedance v1 Pro text-to-video generation and need per-call USDC payment via x402 protocol. It is ideal for autonomous agents that need direct, model-named access to Seedance without managing fal.ai API keys, and when you need configurable duration (5s or 10s), resolution (480p/720p), and aspect ratio (16:9, 9:16, 1:1, 4:3).

## Known failure modes

- Invalid or missing prompt returns a 400 or validation error
- Unsupported aspect_ratio or resolution value may cause generation failure
- Network timeout if fal.ai backend takes too long for complex prompts
- Insufficient USDC balance or x402 payment failure blocks the call
- Model override to a non-existent fal.ai model slug returns an error

## How this service works

Generates AI video with fal.ai Bytedance Seedance. Duration, aspect ratio, and resolution are configurable. Same backend as text-to-video under a model-named slug for direct discovery by agents searching for Seedance. Use it for Seedance video generation, text-to-video AI, and cinematic AI clips.

## Output

Returns a JSON object containing a direct video_url (MP4 hosted on fal.media), the seed used for generation, the model identifier, original prompt, duration, resolution, aspect ratio, and a fal_request_id for reference.
