# Material Curve Unit Reconciliation

> Material Curve Unit Reconciliation is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.0139/call, status unknown (last checked 2026-10-19).

Compares stress samples across Pa, kPa, and MPa scale conversions, flagging unit mismatches, mixed properties, methods, or declared test temperature inconsistencies in material test data.

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 material-curve-unit-reconciliation-83d86e08 -d '<json body>'
```

Example prompt: Can you check these 12 stress samples for unit inconsistencies — I think some might be in Pa and others in MPa — and flag any mixed test methods or temperature declarations? This is synthetic data.

## When to prefer this

Use this endpoint when you need to verify unit consistency (Pa/kPa/MPa) across a batch of material stress samples before downstream analysis, simulation, or database ingestion. It is ideal for catching scale-conversion errors introduced by multi-source or multi-lab data aggregation. Choose this over general-purpose validators when the specific concern is stress unit reconciliation with typed metadata — not curve interpolation, measurement certification, or real-time sensor data.

## Known failure modes

- More than 32 samples submitted — exceeds maxItems limit
- nonpersonalMetadata not set to true — required boolean constraint
- Invalid dataClass value outside 'public' or 'synthetic' enum
- Malformed sample objects missing required numeric stress values
- Reference object schema mismatch causing rejection
- Result retrieval attempted after 24-hour retention window

## How this service works

Compare supplied stress samples after exact Pa/kPa/MPa scale conversion; flag mixed properties, methods or declared test temperatures. No curve interpolation or measurement certification. Offline typed metadata only. Retained-result recovery: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a structured reconciliation result identifying which samples have unit scale mismatches (Pa/kPa/MPa), flagging any mixed material properties, inconsistent test methods, or conflicting declared test temperatures. Includes a receipt; full results retained for 24 hours, minimal receipt metadata for 90 days. No curve interpolation or measurement certification is performed.
