# Quantum Calibrations - Schema Directionality

> Quantum Calibrations - Schema Directionality is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035139/call, status unknown (last checked 2026-10-16).

Compares closed export-field directionality in a supplied record analysis against a declared schema frame, not independent certification.

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-schema-directionality-4157780d -d '<json body>'
```

Example prompt: Can you compare the schema directionality of these two field sets — before has fields [A, B, C] and after has fields [A, B, D] — using the synthetic data class, with nonpersonal metadata only, and let me know if extra fields are allowed?

## When to prefer this

Use this endpoint when you need to compare schema directionality across two field-state snapshots (before/after) within a closed export frame, particularly when working with public or synthetic data classes and nonpersonal metadata constraints. Prefer this over general schema diff tools when the specific directionality semantics of Maha Strategies' calibration framework are required.

## Known failure modes

- before array is empty or missing (minItems:1 required)
- after array exceeds 32 items (maxItems exceeded)
- dataClass not one of 'public' or 'synthetic'
- nonpersonalMetadata not set to true (const:true required)
- Malformed input arrays causing parse errors
- Service unavailable or payment not processed

## How this service works

Compare closed export-field Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a schema directionality comparison report for the supplied before/after field arrays, indicating whether closed export-field directions are consistent within the declared frame, along with any field-level discrepancies or coverage gaps. Not an independent certification.
