## 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 thermal-expansion-mismatch-calculator-05999a80 -d '<json body>'
```

Example prompt: Can you estimate the thermal expansion mismatch strain between a silicon film with a CTE of 2.6e-6 per K and an alumina substrate with a CTE of 6.5e-6 per K over a temperature swing of 200 K? This is for a preliminary public-data scenario.

## When to prefer this

Choose this endpoint when you need a fast, inexpensive preliminary numerical estimate of differential thermal strain between a thin film and a substrate during early design or material selection. It is ideal for screening CTE compatibility before committing to more detailed finite-element or reliability simulations. Not suitable for stress analysis, delamination prediction, or any reliability certification.

## Known failure modes

- Missing required fields (alphaFilmPerK, alphaSubstratePerK, or deltaTemperatureK) return a validation error
- Values outside the allowed numeric range trigger a boundary error
- Invalid or missing dataClass enum value causes a request rejection
- Payment failure or insufficient USDC balance prevents call execution
- Server-side computation error returns a 5xx response

## How this service works

Estimate differential strain from supplied expansion coefficients and temperature changes. For preliminary scenarios; no stress, delamination or reliability certification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

## Output

Returns the estimated differential strain (dimensionless or in strain units) arising from the mismatch between the two supplied thermal expansion coefficients over the given temperature change. This is a preliminary numerical estimate for screening purposes only; it does not include stress, delamination risk, or reliability certification.
