# Ceramic Measurements - Condition Coverage Map

> Ceramic Measurements - Condition Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035198/call, status unknown (last checked 2026-10-16).

Compares declared bulk and pore-free-solid density ratios against a caller-declared density-deficit fraction in integer ppm to validate condition coverage for ceramic material lots.

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 ceramic-measurements-condition-coverage-map-2b47ffe1 -d '<json body>'
```

Example prompt: Check if our ceramic material lot 'CLT-2024-88' with dataset ref 'DS-CERAMIC-001' meets condition coverage — compare bulk to pore-free-solid density ratios using method digest 'md5:abc123', a tolerance of 500 ppm, and classify the data as synthetic with revision 'v2'.

## When to prefer this

Use this endpoint when you need to programmatically validate ceramic material density ratios against a caller-declared deficit fraction in ppm, particularly when working with material lot references and dataset manifests in a materials science or manufacturing QA workflow. Not suitable as an independent certification — results are based solely on caller-supplied data.

## Known failure modes

- Missing required fields (ceramicRef, datasetRef, methodDigest) return validation errors
- tolerancePpm out of range (0–10000) rejected with schema error
- rows array empty or exceeding 32 items returns constraint violation
- Invalid dataClass enum value causes request rejection
- nonpersonalMetadata not set to true (const) causes rejection

## How this service works

Compare declared bulk and pore-free-solid density ratios in one exact unit against a caller-declared density-deficit fraction in integer ppm, using an inclusive caller Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a condition coverage map indicating whether the declared bulk-to-pore-free-solid density ratios satisfy the caller-supplied density-deficit fraction within the specified ppm tolerance, based on the provided measurement rows and references. Does not constitute independent certification.
