# Payment Quotes Export Semantic Parity Check

> Payment Quotes Export Semantic Parity Check is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.0393/call, status unknown (last checked 2026-10-16).

Compares two arrays of parsed payment quote exports for semantic equivalence, ignoring array order, while preserving asset, chain, payee, amount, expiry, and resource pin fields.

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 payment-quotes-export-semantic-parity-check-506c9065 -d '<json body>'
```

Example prompt: Compare these two batches of payment quote exports — the 'before' set has 5 quotes and the 'after' set has 5 quotes, all public data — and tell me if they're semantically equivalent, specifically checking asset, chain, payee, amount, expiry, and resource pins, ignoring array ordering.

## When to prefer this

Use this endpoint when you need a deterministic, order-agnostic semantic comparison of two payment quote export snapshots and want field-level parity checks across asset, chain, payee, amount, expiry, and resource pins — without floating-point price conversion or live verification. Ideal for pipeline integrity checks, pre-settlement audits, and version drift detection on nonpersonal, public or synthetic quote metadata.

## Known failure modes

- Array exceeds 32-item limit — request rejected with validation error
- nonpersonalMetadata not set to true — request rejected as invalid
- dataClass value outside allowed enum ('public', 'synthetic') — schema validation error
- Malformed quote objects in before/after arrays — parsing error returned
- Service unavailable — transient 5xx error requiring retry

## How this service works

Compare parsed quote exports while preserving asset, chain, payee, amount, expiry and resource pins. Array order is ignored; no floating-point price conversion or actual challenge verification. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a semantic parity report indicating whether the before and after quote arrays are equivalent, with field-level details on any mismatches found across asset, chain, payee, amount, expiry, and resource pin dimensions. Array ordering differences are ignored. No floating-point price conversion or live challenge verification is performed. Results are retained for 24 hours; minimal receipt metadata for 90 days.
