# Ceramic Measurements Identifier Crosswalk Audit

> Ceramic Measurements Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035196/call, status unknown (last checked 2026-10-20).

Audits one-to-one alias mappings across typed pins in ceramic lot/method-pinned measurement records, checking identifier 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 ceramic-measurements-identifier-crosswalk-audit-7f662e62 -d '<json body>'
```

Example prompt: Can you run an identifier crosswalk audit on these 15 ceramic measurement rows using my alias mappings, treating the data as synthetic and non-personal, to check if all the typed pins have consistent one-to-one aliases?

## When to prefer this

Choose this endpoint when you need to audit identifier alias consistency specifically within ceramic measurement datasets that use typed pins and lot/method-based pinning. It is best suited for supplied-record analysis of identifier crosswalk integrity, not for certification, ownership verification, or general-purpose record deduplication outside the ceramic measurement domain.

## Known failure modes

- rows array exceeds 32-item limit or is empty — request rejected
- mappings array exceeds 32-item limit or is empty — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true (const constraint violation) — request rejected
- Malformed row or mapping objects — schema validation failure

## How this service works

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

## Output

Returns an audit report identifying any one-to-one alias mismatches or inconsistencies found across typed pins in the submitted ceramic measurement rows, based on the supplied mappings. Does not establish ownership, rights, or authenticity — strictly a supplied-record analysis.
