# Provenance Manifests - Export Semantic Parity

> Provenance Manifests - Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039307/call, status unknown (last checked 2026-10-16).

Compares two sets of typed provenance manifest records for semantic parity by checking parsed field projections, preserving pins and scope, while ignoring record ordering.

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-export-semantic-parity-12312b3b -d '<json body>'
```

Example prompt: Compare these two sets of provenance manifests for semantic parity — up to 10 records in 'before' and 10 in 'after', both classified as public, nonpersonal metadata only — and tell me if the typed record projections match with all pins and scope preserved, ignoring any ordering differences.

## When to prefer this

Choose this endpoint when you need to verify semantic equivalence between two versions of typed provenance manifest records — particularly when record ordering may have changed but content parity must be confirmed. It is specifically suited for offline, nonpersonal metadata validation of public or synthetic artifact/dataset provenance, not for cryptographic signature verification, source downloads, build reproduction, or proof of origin.

## Known failure modes

- Exceeds array size limit (max 32 items per array) — request rejected
- nonpersonalMetadata not set to true — validation error
- Invalid dataClass value (must be 'public' or 'synthetic') — enum validation failure
- Empty or malformed manifest entries — parsing error
- Service unavailable or timeout — no result returned
- Payment failure via x402 protocol — request not processed

## How this service works

Compare parsed typed record projections, preserving all pins and scope while ignoring order; not raw-byte equality or proof of the underlying artifact 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 semantic parity assessment comparing parsed typed record projections between 'before' and 'after' manifest arrays, indicating whether pins and scope are preserved. Results indicate match/mismatch at the field projection level, not raw byte equality. Full result retained for 24 hours; minimal receipt metadata retained for 90 days.
