## 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-quick-d2a05d7a -d '<json body>'
```

Example prompt: Screen this comment before I publish it on my teen-focused platform — apply a strict no-adult-content, no-bullying policy and tell me if it's safe to post: 'You're so ugly no one will ever love you, just disappear.'

## When to prefer this

Choose this endpoint when you need a fast, per-call, pay-as-you-go content moderation decision with explicit policy control, a calibrated violation-risk score, and cited reasons — especially in agentic pipelines where fail-closed behavior and auditability matter. Prefer it over embedding-based classifiers when you need policy customization per call, or over large-model self-moderation when you need a dedicated, accountable trust signal with a payment receipt for audit trails.

## Known failure modes

- Content or policy field exceeds 2000-character limit — returns a validation error
- Missing required 'content' field — returns a 422 unprocessable entity
- Payment not included or insufficient USDC — returns 402 Payment Required
- Ambiguous content where context is absent may result in a more conservative (fail-closed) decision than expected
- Service unavailable or timeout — no partial results returned due to fail-closed design

## How this service works

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

## Output

Returns a structured object with a binary pass/fail decision, a violation_risk score (0–1), a non-empty array of human-readable reasons citing the specific content span and the policy clause it implicates, and an optional receipt for the per-call payment.
