## 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-deployer-x402-deployer-workers-dev-e30f7238 -d '<json body>'
```

Example prompt: Check this comment for harmful content and tell me whether to allow, review, or block it — specifically look for harassment, hate speech, and spam: 'You should be ashamed of yourself, nobody wants you here. Buy followers now at spamsite.com!'

## When to prefer this

Use this endpoint when you need a fast, structured safety verdict with named categories (including custom ones) and an actionable allow/review/block decision. Prefer it over generic LLM prompting for content moderation when you need consistent scoring, audit trails, or integration into automated content pipelines.

## Known failure modes

- Empty or missing text input returns a 400 validation error
- Extremely long text may be truncated or rejected
- Unsupported custom category definitions may be ignored or cause errors
- Payment failure via x402 protocol returns 402 Payment Required
- Ambiguous borderline content may return 'review' verdict without clear category scores

## How this service works

Content moderation / safety classifier / OpenAI-style toxicity API. Morpheus primary, Venice fallback. Scores harassment, hate_speech, violence, sexual_content, self_harm, spam, phishing, doxing, illegal_activity, plus custom categories, and returns allow/review/block.

## Output

Returns per-category scores (e.g. harassment, hate_speech, violence, sexual_content, self_harm, spam, phishing, doxing, illegal_activity), a top-level verdict of allow/review/block, and any flagged categories with confidence signals.
