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 mahastrategies-materials-thermal-expansion-mismatch-calculator-3854d06e -d '<json body>'
```

Example prompt: Can you estimate the differential thermal expansion strain between a silicon nitride film with a CTE of 3.3e-6 per K and a silicon substrate with a CTE of 2.6e-6 per K when the temperature changes by 250 K? Use public data class.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, first-order estimate of thermal expansion mismatch strain between a film and substrate for preliminary materials screening or design feasibility checks. It is ideal for automated pipelines that need a quick numeric result without requiring full FEA or certified reliability analysis. Prefer alternatives when you need stress values, delamination risk assessment, or certified reliability data for production use.

## Known failure modes

- Missing required fields (alphaFilmPerK, alphaSubstratePerK, deltaTemperatureK, dataClass) return validation errors
- Values outside the allowed numeric range (±1e12) are rejected
- Invalid dataClass enum value (not 'public' or 'synthetic') causes schema rejection
- Payment failure or insufficient USDC balance blocks the request
- No stress, delamination, or reliability certification — results are preliminary only and may not reflect full mechanical behavior

## How this service works

Estimate differential strain from supplied expansion coefficients and temperature changes. For preliminary scenarios; no stress, delamination or reliability certification.

## Output

Returns a structured result object containing the computed differential strain estimate along with metadata including offer ID, version, input digest, receipt digest, amount in base units, and any applicable boundary conditions flagged during the calculation.
