## 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-concord-quick-policy-compliance-checker-f6dc7bf8 -d '<json body>'
```

Example prompt: Check whether this draft response — 'Our product guarantees 100% uptime and full refunds within 24 hours' — complies with our SLA policy: 'Section 3.1: Uptime commitments must not exceed 99.9%. Section 4.2: Refund processing times must be stated as up to 5 business days.' Focus especially on the uptime and refund clauses.

## When to prefer this

Choose this endpoint when you need a calibrated, fail-closed compliance verdict with per-clause reasoning rather than a binary pass/fail. It is especially well-suited for AI agent pipelines where outputs must be gated against a known policy before delivery, or when you need a signed, auditable receipt of the compliance check. Prefer it over generic LLM prompting for compliance when you need structured verdicts, consistent partial/uncertain signaling, and a cryptographically verifiable audit trail.

## Known failure modes

- Missing required 'policy' or 'text' fields returns a validation error
- Text or policy exceeding 2000 characters is rejected
- Ambiguous or vague policy language may result in an 'uncertain' verdict rather than a clear pass/fail
- Payment failure (insufficient USDC) blocks the call under x402 protocol
- Scope note misalignment may cause clause coverage gaps in reasoning

## How this service works

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

## Output

Returns a structured JSON object with a 'verdict' (compliant, non_compliant, partial, or uncertain), a 'compliance' summary, a list of 'violations', and an array of 'reasons' providing concrete per-clause reasoning tied to specific clause text and the evaluated input. Optionally includes an Ed25519-signed VerityLayer receipt for auditability.
