# Materials Sheet Resistance Calculator

> Materials Sheet Resistance Calculator is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.023001/call, status unknown (last checked 2026-10-21).

Computes sheet resistance from film thickness and bulk resistivity using the standard thin-film formula (ρ/t), for arithmetic verification under uniform-film assumptions.

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 materials-sheet-resistance-calculator-45a24b47 -d '<json body>'
```

Example prompt: Calculate the sheet resistance of a copper thin film with a bulk resistivity of 1.72e-8 Ω·m and a thickness of 200 nanometers (2e-7 m) — use the public data class.

## When to prefer this

Choose this endpoint when you need a fast, deterministic arithmetic check of the sheet resistance formula (ρ/t) for a uniform thin film and want a verifiable, receipted result — not when you need measured device performance data or empirical characterization of a real sample.

## Known failure modes

- Missing required fields (dataClass, resistivityOhmM, thicknessM) returns a validation error
- Zero thickness input may produce a division-by-zero or boundary error
- Values outside the allowed range (0 to 1e12) are rejected
- Invalid bodyType or method returns a schema mismatch error
- Network or payment authorization failure prevents processing

## How this service works

Relate supplied film thickness, resistivity and sheet resistance under stated uniform-film assumptions. For arithmetic checks; no measured device-performance claim.

## Output

Returns a result object containing the computed sheet resistance value, alongside versioning metadata, an offer ID ('materials-sheet-resistance'), an input digest and receipt digest for traceability, and any boundary conditions flagged during calculation.
