# Reaction Records Identifier Crosswalk Audit

> Reaction Records Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035166/call, status unknown (last checked 2026-10-16).

Checks one-to-one aliases (identifier crosswalks) across typed pins for reaction records, reporting mapping consistency without establishing 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 reaction-records-identifier-crosswalk-audit-f37e9da7 -d '<json body>'
```

Example prompt: Check the identifier crosswalk for these reaction records — I have up to 20 rows and 20 mappings I want to audit for alias consistency; the data class is synthetic and it's all non-personal metadata.

## When to prefer this

Choose this endpoint when you need to audit identifier alias consistency (crosswalk integrity) specifically for reaction records with typed pins, and your data is either public or synthetic non-personal metadata. It is narrowly scoped to reaction record identifier mapping — not general record deduplication, ownership verification, or authenticity certification.

## Known failure modes

- rows or mappings arrays exceed 32-item limit — request rejected
- nonpersonalMetadata not set to true — validation error
- invalid dataClass value outside 'public' or 'synthetic' enum — schema error
- mismatched row/mapping counts causing incomplete crosswalk analysis
- empty rows or mappings arrays below minItems:1 — rejected
- network or payment failure (x402 protocol issue)

## How this service works

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

## Output

Returns an audit report indicating which identifier aliases match correctly across typed pins, flags mismatches or broken crosswalk links, and notes any mapping inconsistencies — without certifying ownership, rights, or authenticity of the underlying reaction records.
