## 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 verity-suite-sieve-content-moderation-screener-3900539c -d '<json body>'
```

Example prompt: Before publishing this user comment to our forum, screen it against our policy of no hate speech, harassment, or self-harm promotion: 'You people are all the same and deserve what's coming to you.' The audience is a general public community forum.

## When to prefer this

Choose this endpoint when you need a calibrated, fail-closed moderation decision with explicit reasons and an audit trail, especially when deploying AI agents that publish user-generated content and need per-call pay-as-you-go pricing without a subscription. Prefer it over LLM-prompt-based moderation when you need structured, signed outputs and policy-level traceability.

## Known failure modes

- Content exceeds 2000 character limit — request rejected with validation error
- Missing required 'content' field — returns schema validation error
- Policy string exceeds 2000 character limit — rejected
- Service unavailable or payment failure — fail-closed, content not approved by default
- Ambiguous policy language may lead to conservative interpretation

## How this service works

The trust fabric for AI agents — calibrated, fail-closed services agents pay per call.

## Output

A structured response containing a binary moderation decision (pass/block), a violation risk score, and a non-empty array of concrete reasons citing specific spans of content and the policy clause or baseline rule implicated. Optionally includes an audit receipt object.
