# Materials Qualification Evidence Brief

> Materials Qualification Evidence Brief is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.298962/call, status unknown (last checked 2026-10-21).

Reconciles a list of required qualification tests against supplied pass/fail/not-run evidence records, reporting declared passes, failures, and gaps without issuing material 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 materials-qualification-evidence-brief-0d4aea79 -d '<json body>'
```

Example prompt: Check our qualification test evidence for the 'ThermalCoat-7' application — data class is synthetic — against these required tests: tensile-strength, adhesion, thermal-cycling, and corrosion-resistance. We have evidence records showing tensile-strength passed, adhesion failed, and thermal-cycling not run. List the passes, failures, and any gaps.

## When to prefer this

Use this endpoint when you need a deterministic, auditable reconciliation of qualification test requirements against evidence records — particularly for materials or engineering applications where you need a structured gap analysis without triggering a formal certification workflow. Prefer this over manual review or general-purpose LLMs when you need a reproducible, schema-verified output with input/receipt digests for audit trails.

## Known failure modes

- Missing required fields (dataClass, application, requiredTests) causes validation error
- Evidence array exceeding 64 items or requiredTests exceeding 32 items rejected
- Invalid dataClass enum value (must be 'public' or 'synthetic') causes rejection
- Empty requiredTests array causes schema validation failure
- Malformed evidence record objects may cause processing errors

## How this service works

Reconcile required qualification tests with supplied pass/fail/not-run evidence records. List declared passes, failures and gaps; no material certification.

## Output

Returns a structured result object listing which required tests have declared passes, which have declared failures, and which have no evidence (gaps), along with boundary annotations and digests for input and receipt verification. No formal material certification is issued.
