# Source Packs Export Semantic Parity

> Source Packs Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039298/call, status unknown (last checked 2026-10-20).

Compares two sets of source-pack exports for semantic parity, checking that source identity, edition pins, content pins, byte counts, media labels, and access labels match, independent of ordering.

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 source-packs-export-semantic-parity-adb97991 -d '<json body>'
```

Example prompt: Compare these two sets of source-pack exports — before and after the migration — using public data class, and tell me whether the source identity, edition pins, content pins, byte counts, media labels, and access labels all match semantically, ignoring order differences.

## When to prefer this

Use this endpoint when you need to verify semantic equivalence between two snapshots of source-pack exports — particularly after migrations, updates, or transformations — where ordering differences should be ignored but identity, edition, content pins, byte counts, and media/access labels must match. This is a pure offline, typed, nonpersonal metadata comparison and does not verify content truth or licensing validity.

## Known failure modes

- Array exceeds 32 items — returns validation error
- nonpersonalMetadata not set to true — required constant, rejected if omitted or false
- dataClass not one of 'public' or 'synthetic' — enum violation error
- Empty arrays on both sides — may return trivially equal result with no useful diff
- Malformed pin structures in array elements — parsing error returned
- Timeout if source pack arrays are large or complex
- Network error resulting in no response

## How this service works

Compare parsed source-pack exports while preserving source identity, edition and content pins, byte counts, media and access labels. Order is ignored; content, licensing and source truth are not verified. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

A structured parity report indicating whether the before and after source-pack export arrays are semantically equivalent, with details on any mismatches across source identity, edition pins, content pins, byte counts, media labels, and access labels. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
