## 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 mistral-ai-content-moderation-via-locus-x402-baa926c2 -d '<json body>'
```

Example prompt: Can you run this user comment through Mistral's content moderation to check if it violates any safety policies? The text is: 'You should seriously just disappear forever, nobody wants you here.'

## When to prefer this

Choose this endpoint when you need fast, per-call text moderation powered by Mistral's dedicated moderation model without managing API keys or subscriptions — ideal for agents that pay per use via x402/USDC micropayments. Prefer this over general LLM classification prompts when you want a purpose-built moderation model with defined safety categories rather than a freeform generation-based classifier.

## Known failure modes

- Empty or null input array returns an error or empty results
- Unsupported model name causes a model-not-found error
- Inputs exceeding token limits are rejected or truncated
- Payment of 0.008 USDC is required — missing or invalid payment header causes a 402 response
- Rate limits may throttle high-volume moderation requests
- Malformed JSON body returns a 400 bad request error
