## 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-nvidia-synthetic-video-detector-18c72df6 -d '<json body>'
```

Example prompt: Can you check whether this video clip is AI-generated or real? I want to know if it was synthetically created by an AI model.

## When to prefer this

Use this endpoint when you need to detect AI-generated or synthetic video content using NVIDIA NIM's specialized detection models, especially when you want pay-per-use access via x402 micropayments without API key subscriptions. Prefer this over generic classifiers when working specifically with synthetic video detection at $0.107 per call.

## Known failure modes

- Invalid or missing video input returns an error response
- Unsupported video format may cause processing failure
- Payment failure via x402 protocol blocks the request
- NVIDIA NIM model unavailability causes downstream errors
- Malformed request body missing required fields returns validation error

## How this service works

Access 48+ NVIDIA NIM AI models via x402 micropayments. Chat completions, vision, safety, translation, and more.

## Output

Returns a choices array containing the model's classification response indicating whether the video is synthetic or authentic, along with the assistant message content describing the detection result.
