# Provenance Manifests Identifier Crosswalk Audit

> Provenance Manifests Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035112/call, status unknown (last checked 2026-10-16).

Checks one-to-one alias mappings between typed identifiers in artifact and dataset provenance manifests, returning a crosswalk audit result without verifying ownership, authenticity, or signatures.

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-identifier-crosswalk-audit-d57e4d94 -d '<json body>'
```

Example prompt: Can you run a crosswalk audit on these two lists of identifier mappings — up to 32 rows and 32 mappings — treating the data as public, nonpersonal metadata, and tell me which aliases match one-to-one across the typed pins?

## When to prefer this

Use this endpoint when you need a lightweight, offline crosswalk audit of identifier alias mappings within nonpersonal provenance manifests — specifically when you only need to check one-to-one alias consistency across typed pins and do not require signature verification, ownership proof, or source download. It is well-suited for governance pre-checks and metadata reconciliation on public or synthetic data, and is not a substitute for full cryptographic provenance verification.

## Known failure modes

- Rows or mappings array exceeds 32 items — request rejected
- nonpersonalMetadata not set to true — validation error
- dataClass not one of 'public' or 'synthetic' — enum validation failure
- Malformed identifier rows or mappings format — parse error
- Service unavailable or timeout — no audit result returned

## How this service works

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity 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 crosswalk audit report indicating which identifier aliases match one-to-one against their typed pins, along with unmapped or mismatched entries. Does not establish ownership, rights, or authenticity; does not verify signatures or reproduce builds. Full results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
