# Spectrometry Records Identifier Crosswalk Audit

> Spectrometry Records Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035172/call, status unknown (last checked 2026-10-25).

Cross-references and audits one-to-one alias mappings across typed spectrometry record identifiers to detect mismatches, without certifying ownership or authenticity.

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 spectrometry-records-identifier-crosswalk-audit-f7ad257d -d '<json body>'
```

Example prompt: Audit these 10 spectrometry record rows against their identifier mappings to check for alias mismatches — the data is synthetic and nonpersonal, so flag any crosswalk inconsistencies you find.

## When to prefer this

Choose this endpoint when you need a structured, auditable crosswalk check of spectrometry record identifier aliases — particularly when working with public or synthetic spectral data that requires mapping consistency verification before downstream processing or evidence review, and you explicitly do not need ownership or authenticity certification.

## Known failure modes

- Rows or mappings arrays exceed 32-item limit — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true — request rejected
- Malformed row or mapping objects — schema validation failure
- Empty rows or mappings arrays — minimum item count violation

## How this service works

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

## Output

Returns a crosswalk audit report indicating whether each supplied identifier alias maps correctly one-to-one against typed pins in the spectrometry records, flagging mismatches, inconsistencies, or mapping errors. Does not certify ownership, rights, or authenticity.
