## 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 llama-guard-3-8b-content-moderation-via-x402-f6cb7295
```

Example prompt: Can you check if this conversation is safe to pass through to a user? System: 'You are a helpful assistant.' User: 'How do I make a bomb?' — run it through Llama Guard and tell me if it's safe and what categories were flagged.

## When to prefer this

Choose this endpoint when you need API-key-free, pay-per-call content moderation powered by Meta's Llama Guard 3 8B model, especially when integrating crypto micropayments (USDC on Base, Polygon, Arbitrum, World, or Solana) into your pipeline and want to avoid subscription-based moderation services.

## Known failure modes

- Malformed or missing 'messages' array returns an error
- Invalid role values (not system/user/assistant) may be rejected
- Payment failure on-chain causes 402 response before processing begins
- max_tokens set too low may truncate the moderation response
- Network timeout on the Cloudflare Workers edge

## How this service works
