# Alloy Measurements - Condition Coverage Map

> Alloy Measurements - Condition Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035192/call, status unknown (last checked 2026-10-16).

Validates that up to 32 caller-declared alloy constituent labels sum to 1,000,000 parts-per-million within a caller-specified inclusive tolerance (0–10,000 ppm), checking compositional completeness on supplied records.

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 alloy-measurements-condition-coverage-map-9240f27b -d '<json body>'
```

Example prompt: Check whether my mass-basis alloy constituents — Iron at 700000 ppm, Chromium at 180000 ppm, Nickel at 100000 ppm, and Carbon at 20000 ppm — all sum correctly to 1,000,000 ppm within a tolerance of 500 ppm, using dataset reference 'lot-2024-A7' and public data class.

## When to prefer this

Choose this endpoint when you need to programmatically verify that a set of caller-declared alloy constituent labels achieves complete compositional coverage (summing to 1,000,000 ppm) within a known tolerance, particularly for materials science pipelines, quality control workflows, or pre-export validation of alloy lot records. It is best suited for validating supplied records rather than seeking independent third-party certification, and supports both mass and atom basis declarations.

## Known failure modes

- Constituent array exceeds 32 items — request rejected
- Tolerance value outside 0–10,000 range — validation error
- Constituent ppm values sum outside the tolerance band — coverage condition fails
- Missing required constituents field — schema validation error
- Invalid basis enum value (not 'mass' or 'atom') — bad request
- nonpersonalMetadata not set to true — request rejected
- Invalid or unresolvable datasetRef — record not found error

## How this service works

Check whether at most 32 unique caller-declared constituent labels sum to 1,000,000 integer parts-per-million within an inclusive caller tolerance of 0–10,000 Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a condition coverage map indicating whether the declared constituent labels sum to exactly 1,000,000 ppm within the caller-specified inclusive tolerance, along with pass/fail status for each coverage condition, the computed sum, and any out-of-tolerance details. This is a supplied-record analysis, not independent certification.
