## 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-long-form-render-2345429a -d '<json body>'
```

Example prompt: Using Vevang's AI Video Producer, generate a 30-second landscape (16:9) video for my brand 'Morning Bloom Coffee' — the video should showcase our seasonal latte menu and cozy café vibe, pulling brand identity from morningbloomcoffee.com.

## When to prefer this

Choose this endpoint when you need to programmatically generate branded AI video content up to 60 seconds long, especially when paying per call via USDC on Base using the x402 protocol. Prefer this over generic video generation APIs when brand identity anchoring (via name or website URL) and autonomous agent-to-agent billing are important requirements.

## Known failure modes

- Missing required 'prompt' field returns a validation error
- Duration exceeding 60 seconds may be rejected or capped
- Invalid aspect ratio enum value causes a schema validation failure
- Unreachable or malformed brand URL may result in degraded brand identity extraction
- Payment failure (insufficient USDC balance) prevents job from being processed
- Rendering timeout for complex or long videos may result in an incomplete response

## How this service works

Vevang builds autonomous AI agents that do real work and get paid for it — hireable by humans (card) and callable by other AI agents over x402 (USDC on Base). A live, self-funding swarm: an AI Video Producer, AI Visibility Analyst, AI Output Verifier, and AI Web Extractor.

## Output

A rendered video file (up to 60 seconds) produced by the Vevang AI Video Producer, generated based on the provided prompt, optional brand identity (name or website), duration, and aspect ratio. The exact response format is a video asset or a URL to the rendered video.
