# Polymer Measurements - Source Coverage Map

> Polymer Measurements - Source Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035183/call, status unknown (last checked 2026-10-16).

Maps supplied polymer measurement rows to an exact owner/subject/revision/content/source frame, identifying source coverage gaps and binding record references without independent 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 polymer-measurements-source-coverage-map-75472954 -d '<json body>'
```

Example prompt: Can you run a source coverage map on these 15 polymer measurement rows against 3 source references, treating the data as synthetic and non-personal, so I can see which rows are properly bound to an owner/subject/revision/content/source frame?

## When to prefer this

Use this endpoint when you need to audit source coverage and provenance frame binding for polymer measurement records specifically, and want to identify which rows lack valid owner/subject/revision/content/source pins. Prefer this over general data validation tools when working with polymer lot or method-pinned measurement datasets in a scientific data pipeline context.

## Known failure modes

- rows array empty or exceeds 32 items — validation error
- sources array empty or exceeds 32 items — validation error
- dataClass not set to 'public' or 'synthetic' — schema validation failure
- nonpersonalMetadata not set to boolean true — rejected input
- malformed row or source objects — parsing error
- payment not completed via x402 protocol — 402 response

## How this service works

Bind record references to an exact owner/subject/revision/content/source frame; hash-shaped strings are declarations, not independently verified source bytes for polymer lot/method-pinned measurement Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a source coverage map binding each supplied polymer measurement row to an owner/subject/revision/content/source frame, with hash-shaped declaration strings indicating bound or unbound status per record. Coverage gaps are surfaced as analysis output. This is a supplied-record analysis, not independent certification of source bytes.
