## 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 vevang-ai-video-producer-short-video-renderer-cd6c5e8a -d '<json body>'
```

Example prompt: Use Vevang to render a 10-second vertical 9:16 short video for my brand 'SunBloom Coffee' — the brief is 'a cozy morning coffee ritual with warm lighting and relaxing vibes'.

## When to prefer this

Choose this endpoint when you need autonomous, per-call AI video generation with built-in USDC micropayment support (x402/Base), especially for agent-to-agent workflows where a calling AI needs to commission a short branded video without human intervention. Prefer this over generic video APIs when you want a self-funding agent swarm model and native crypto payment rails rather than OAuth or API-key billing.

## Known failure modes

- Missing required 'prompt' field returns a validation error
- Duration exceeding 15 seconds is rejected
- Invalid aspect ratio enum value returns a schema error
- Brand URL unreachable may result in degraded brand identity extraction
- Payment failure in USDC/x402 prevents job from starting
- Video generation timeout for complex prompts

## How this service works

AI Video Producer — turn one prompt into a finished, on-brand short video (script, AI voiceover, cinematic visuals, cut), up to 15s. POST JSON: prompt + a brand or url. Returns a ready-to-post mp4 URL.

## Output

A rendered short video asset (up to 15 seconds) matching the provided prompt and brand identity, in the requested aspect ratio. The agent receives the video output from Vevang's AI Video Producer, ready for social media, ads, or downstream publishing.
