## 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 polymer-measurements-identifier-crosswalk-audit-4957ea60 -d '<json body>'
```

Example prompt: Can you audit these polymer measurement rows and their identifier mappings against the pinned records? I have up to 20 rows and 20 mappings, all synthetic, non-personal data — I need to know if any one-to-one aliases are inconsistent with the typed pins.

## When to prefer this

Choose this endpoint when you need to programmatically audit identifier alias mappings against polymer measurement records pinned by lot or method, particularly for data quality checks on supplied records. Prefer this over generic data validation tools when the domain is polymer measurement metadata and you need explicit crosswalk analysis of one-to-one identifier relationships.

## Known failure modes

- Rows or mappings arrays exceed 32 items — request rejected
- dataClass value not in enum (public, synthetic) — validation error
- nonpersonalMetadata not set to true (const constraint) — request rejected
- Mismatched row/mapping counts leading to incomplete crosswalk results
- Malformed alias structures causing partial audit output

## How this service works

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

## Output

Returns an audit report detailing which one-to-one identifier aliases match or conflict with the typed polymer lot/method-pinned measurement records, highlighting any crosswalk inconsistencies without establishing ownership, rights, or authenticity certification.
