# Alloy Measurements - Identifier Crosswalk Audit

> Alloy Measurements - Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.03519/call, status unknown (last checked 2026-10-25).

Checks one-to-one identifier aliases across typed alloy measurement pins to audit crosswalk consistency without certifying ownership or authenticity.

## 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 alloy-measurements-identifier-crosswalk-audit-3b9e5cc1 -d '<json body>'
```

Example prompt: Can you audit my alloy measurement identifier crosswalk? I have up to 20 rows and 15 mappings using public data — flag any aliases that don't resolve one-to-one across the typed pins.

## When to prefer this

Choose this endpoint when you need a lightweight, per-call audit of alloy measurement identifier aliases across a bounded set of rows and mappings, particularly when you want to detect crosswalk inconsistencies without requiring independent certification or ownership verification. Prefer it over manual reconciliation tools when working with public or synthetic alloy datasets and needing a structured, machine-readable audit result.

## Known failure modes

- rows or mappings array empty or exceeds 32-item limit — validation error
- dataClass not one of 'public' or 'synthetic' — enum rejection
- nonpersonalMetadata not set to true (const) — request rejected
- malformed or incompatible identifier formats in rows/mappings — audit cannot resolve aliases
- network timeout on large payloads near the 32-item limit

## How this service works

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity for alloy lot/method/composition-basis Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an audit report listing which identifier aliases satisfy or violate one-to-one crosswalk conditions across the supplied typed pins, including which rows and mappings failed, without certifying ownership, rights, or authenticity of the underlying alloy records.
