# Battery Measurements - Export Semantic Parity

> Battery Measurements - Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039322/call, status unknown (last checked 2026-10-20).

Compares two sets of parsed battery/cell-config/lot/method-pinned measurement record projections for semantic parity, ignoring field order while preserving all pins and scope.

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 battery-measurements-export-semantic-parity-35678901 -d '<json body>'
```

Example prompt: Compare these two sets of battery measurement records — up to 32 entries each in the before and after arrays — and tell me if they're semantically equivalent (same pins and scope, ignoring field order), treating the data as synthetic and nonpersonalMetadata set to true.

## When to prefer this

Choose this endpoint when you need semantic-level comparison of battery or cell-configuration measurement record projections and want to confirm parity after a transformation, migration, or update — especially when field order may differ between snapshots. Not suitable when you need raw-byte equality, cryptographic proof of the underlying artifact, or independent certification. Best for pipeline validation, QA audits, and change-detection workflows on battery/lot/method-pinned datasets limited to 32 records per side.

## Known failure modes

- Array exceeds 32-item limit — validation error returned
- nonpersonalMetadata not set to true (const constraint violation) — request rejected
- Invalid dataClass value outside of 'public' or 'synthetic' enum — schema error
- Malformed record objects in before/after arrays — parsing failure
- Payment insufficient or x402 protocol failure — authorization error

## 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 battery/cell-config/lot/method-pinned 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 battery measurement record sets are equivalent, with details on any pin or scope mismatches found, ignoring field ordering differences. Does not perform raw-byte equality or provide certification of the underlying artifact.
