# Provenance Manifests - Unit-Label Consistency Check

> Provenance Manifests - Unit-Label Consistency Check is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.012307/call, status unknown (last checked 2026-10-16).

Compares declared unit labels across artifact and dataset provenance manifests within a single pinned frame, without conversion, inference, or source verification.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 provenance-manifests-unit-label-consistency-check-72ba321d -d '<json body>'
```

Example prompt: Check the unit-label consistency across these 12 public artifact provenance manifest measurements — I need to know if any declared labels are mismatched within the same pinned frame, no unit conversion needed.

## When to prefer this

Choose this endpoint when you need a lightweight, offline check of whether unit labels are declared consistently across artifact or dataset provenance manifests, with no need for unit conversion, source file access, signature verification, or scientific validity assessment. It is ideal for pre-submission QA, compliance audits, or pipeline validation steps where metadata is nonpersonal and classified as public or synthetic.

## Known failure modes

- Measurements array empty or exceeds 32 items — request rejected
- nonpersonalMetadata not set to true — request rejected
- dataClass not one of 'public' or 'synthetic' — validation error
- Malformed measurement entries — parsing error or partial result
- Result expired after 24-hour retention window — receipt only available
- Service unavailable — HTTP 402 or 5xx error

## How this service works

Compare declared artifact size labels within a pinned frame; no unit conversion or inferred equivalence for caller-supplied artifact and dataset provenance manifests. No source download, build reproduction, signature verification, proof of origin, causality or scientific validity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a consistency assessment of declared unit labels across the supplied manifest measurements within the pinned frame, flagging any label mismatches or inconsistencies. Full result is retained for 24 hours; minimal receipt metadata is retained for 90 days. No unit conversion, inferred equivalences, source downloads, signature verification, or causal analysis is performed.
