# Polymer Measurements - Export Semantic Parity

> Polymer Measurements - Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039319/call, status unknown (last checked 2026-10-16).

Compares two sets of parsed polymer lot/method-pinned measurement record projections for semantic equivalence, preserving all pins and scope while ignoring record order.

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-export-semantic-parity-8911b46b -d '<json body>'
```

Example prompt: Can you check if these two polymer measurement record sets are semantically equivalent — compare the before set (up to 32 records) and after set using public data class, and tell me if they match ignoring order but preserving all method pins and scope?

## When to prefer this

Use this endpoint when you need to verify that two ordered-differently but semantically identical sets of polymer lot/method-pinned measurement records are equivalent, and you want pin and scope preservation confirmed without raw-byte or cryptographic proof. Prefer this over raw diff tools when order independence and semantic field equivalence (not byte equality) is the requirement.

## Known failure modes

- Array exceeds 32-item limit — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true — request rejected
- Malformed record objects in before/after arrays — parsing error
- Empty or missing arrays — may return trivial parity result

## How this service works

Compare parsed typed record projections, preserving all pins and scope while ignoring order; not raw-byte equality or proof of the underlying artifact for polymer lot/method-pinned measurement Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a semantic parity assessment indicating whether the before and after polymer measurement record projections are equivalent, preserving all method and lot pins and scope boundaries while disregarding record order; flags any discrepancies in pins, scope, or field values between the two sets.
