# Study Notes Export Semantic Parity

> Study Notes Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039296/call, status unknown (last checked 2026-11-04).

Compares two sets of study note records by exact typed metadata fields (notebook, source, revision, claim-kind, basis, locator) without semantic or text analysis, returning a parity result valid for 24 hours.

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 study-notes-export-semantic-parity-877f6a35 -d '<json body>'
```

Example prompt: Compare these two batches of study notes — up to 32 records each, public data class — and check if the notebook, source, revision, claim-kind, basis, and locator fields all match exactly, ignoring text content and row order.

## When to prefer this

Choose this endpoint when you need exact, field-level typed metadata comparison between two exports of study notes and do not need any text analysis, semantic similarity, or NLP. It is specifically designed for offline, nonpersonal metadata parity checks on structured note fields like notebook, source, revision, claim-kind, basis, and locator. Prefer it over general-purpose diff tools when you need a structured receipt and 90-day minimal metadata retention.

## Known failure modes

- More than 32 records supplied in before or after array — rejected with validation error
- dataClass not set to 'public' or 'synthetic' — schema validation failure
- nonpersonalMetadata not set to true — request rejected
- Mismatched or malformed note ID references — parity check returns error or incomplete result
- Result expired after 24-hour retention window — must resubmit
- Network or payment failure via x402 protocol — request not processed

## How this service works

Compare exact typed notebook, source, revision, claim-kind, basis and locator projections by note ID. Row order is ignored; no text or semantic entailment comparison. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a structured parity result indicating whether the typed metadata fields (notebook, source, revision, claim-kind, basis, locator) match exactly across the supplied before and after note record sets. Row order is ignored. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days. No text comparison or semantic entailment is performed.
