## 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 mps-provenance-contract-audit-da6c59e8 -d '<json body>'
```

Example prompt: Audit this provenance contract for me — check that all the claim tags, exact excerpts, evidence-reference IDs, and action declarations are internally consistent. The data is public and non-personal.

## When to prefer this

Choose this endpoint when you need a pure structural and logical consistency audit of a provenance contract — checking claim tags, excerpts, evidence-reference IDs, and action declarations — without requiring model inference, source fetching, or factual certification. Ideal for automated pipelines that need lightweight, CPU-only provenance auditing on public or synthetic non-personal data within the 32 KiB input constraint.

## Known failure modes

- Input exceeds 32 KiB limit — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true — request rejected
- Malformed request object — schema validation failure
- Service unavailable — 5xx error

## How this service works

MPS provenance-contract audit: check caller-declared claim tags, exact excerpts, evidence-reference IDs and action consistency. CPU only; no model calls, source fetching, truth judgments or certification of VERIFIED labels. Public/synthetic nonpersonal input only; 32 KiB input, 65 KB output. Result retention: 24 hours; minimal receipt metadata: 90 days. No model calls or factual certification.

## Output

A structured audit report (up to 65 KB) detailing findings on claim tag correctness, excerpt accuracy, evidence-reference ID alignment, and action consistency within the submitted provenance contract.
