# Quantum Calibrations - Identifier Crosswalk Audit

> Quantum Calibrations - Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035136/call, status unknown (last checked 2026-10-16).

Checks one-to-one alias mappings against typed calibration pins, reporting identifier crosswalk consistency for public or synthetic nonpersonal calibration declarations.

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 quantum-calibrations-identifier-crosswalk-audit-b3c309cb -d '<json body>'
```

Example prompt: Audit my identifier crosswalk for these calibration rows — I have up to 20 rows and 20 mappings, all public and nonpersonal — and tell me which aliases don't match their typed calibration pins.

## When to prefer this

Use this endpoint when you need to verify that calibration identifier aliases correctly map one-to-one to typed calibration pins within bounded, public or synthetic, nonpersonal declaration records. It is appropriate for pre-submission validation, discrepancy detection, and crosswalk auditing of calibration metadata — not for hardware measurement, recalibration, or any operation requiring device access or scientific certification.

## Known failure modes

- Input exceeds 32 KiB limit — request rejected
- More than 32 rows or mappings supplied — validation error
- dataClass not set to 'public' or 'synthetic' — schema validation failure
- nonpersonalMetadata not set to true — request rejected
- Malformed rows or mappings array — parsing error
- No rows or mappings provided (below minItems:1) — validation error

## How this service works

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity for bounded backend/run/register/measurement-pin records. Caller-supplied public/synthetic nonpersonal calibration declarations only. No hardware measurement, device/API access, recalibration, mitigation, performance guarantee or scientific certification. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a crosswalk audit result indicating which alias-to-pin mappings are consistent or inconsistent across the provided calibration rows and mappings, without raw data retention beyond 24 hours; minimal receipt metadata is retained for 90 days.
