# Protein Measurements - Export Semantic Parity

> Protein Measurements - Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039314/call, status unknown (last checked 2026-10-16).

Compares two sets of parsed protein/isoform/sequence-pinned measurement records for semantic parity, preserving pins and scope while ignoring record order.

## 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 protein-measurements-export-semantic-parity-755b12cb -d '<json body>'
```

Example prompt: Can you check whether these two sets of protein measurement records are semantically equivalent — treating them as public data and ignoring any differences in record order? Here are the before records and after records arrays.

## When to prefer this

Use this endpoint when you need to confirm that two snapshots of protein, isoform, or sequence-pinned measurement records are semantically equivalent after a transformation, export, or reordering operation — specifically when you care about preserving pins and scope but want to ignore record order. Prefer this over raw diff tools when working with typed projection records where order is irrelevant to semantic meaning.

## Known failure modes

- Arrays exceeding 32 items are rejected
- dataClass must be 'public' or 'synthetic' — other values cause validation errors
- nonpersonalMetadata must be true (const constraint); omitting or setting false causes rejection
- Malformed record structures in before/after arrays may cause parse errors
- Empty or mismatched record schemas between before and after may yield inconclusive parity results

## 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 protein/isoform/sequence-pinned measurement Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an ordering-independent semantic parity assessment of the two protein measurement record sets, indicating whether pins, scope, and typed projections are preserved between the before and after arrays, without performing raw-byte equality or artifact certification.
