# Polymer Measurements - Duplicate Record Identity Comparison

> Polymer Measurements - Duplicate Record Identity Comparison is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010319/call, status unknown (last checked 2026-10-16).

Compares duplicate owner, subject, and revision declarations across polymer measurement records against every scientific frame in the supplied data.

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-duplicate-record-identity-comparison-be7a78ea -d '<json body>'
```

Example prompt: Can you check these 10 polymer measurement records I have for duplicate owner, subject, and revision declarations? They're all public data and non-personal — I want to know which entries conflict with each other across the scientific frames.

## When to prefer this

Use this endpoint when you need to detect duplicate owner, subject, and revision declarations within a batch of polymer measurement records (up to 32 rows) using supplied-record analysis. Prefer this over general deduplication tools when working specifically with polymer or materials science measurement data that must be validated against scientific frames. Best suited for public or synthetic datasets with non-personal metadata.

## Known failure modes

- Exceeds 32-row limit — request rejected with validation error
- dataClass not set to 'public' or 'synthetic' — enum validation failure
- nonpersonalMetadata not set to true (const) — request rejected
- Empty rows array — minItems constraint violation
- Malformed row objects — schema validation error
- Payment failure — x402 payment required error

## How this service works

Compare duplicate owner/subject/revision declarations against every scientific frame Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a comparison of the supplied polymer measurement rows indicating which records share duplicate owner, subject, and/or revision declarations, mapped against every scientific frame in the provided dataset. Results reflect supplied-record analysis only and do not constitute independent certification.
