# Settlement Receipts Scope Boundary Audit

> Settlement Receipts Scope Boundary Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.038301/call, status unknown (last checked 2026-10-16).

Validates settlement receipt metadata (merchant ref, network, asset/decimal labels) against caller-defined scope boundaries and allowed observation states, without verifying merchant ownership, bank deposits, or cash-out compatibility.

## 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 settlement-receipts-scope-boundary-audit-dc11e4b0 -d '<json body>'
```

Example prompt: Audit these 5 settlement receipts for merchant 'MHST-4492' against allowed networks ['ethereum','polygon'] using asset ref 'USDC' with 6 decimals — data class is 'public', allowed observations are ['pending','settled'] and flag it as nonpersonal metadata only.

## When to prefer this

Choose this endpoint when you need offline, typed, nonpersonal metadata validation of settlement receipt scope boundaries — specifically comparing merchant refs, network labels, and asset/decimal labels against caller-declared constraints. Prefer it over full settlement verification services when you do not need merchant ownership checks, bank deposit confirmation, or cash-out compatibility. Best for compliance auditing, data pipeline validation, or agent workflows that must classify receipt scope before downstream processing.

## Known failure modes

- receipts array empty or exceeds 32 items — validation error
- allowedNetworks exceeds 3 items — schema rejection
- allowedObservations exceeds 4 items — schema rejection
- nonpersonalMetadata not set to true — const constraint violation
- dataClass value outside 'public'/'synthetic' enum — rejection
- decimals outside 0–18 range — schema error
- missing required fields (merchantRef, assetRef) — 400 bad request
- payment not received or insufficient USDC — 402 payment required

## How this service works

Compare receipt merchant, network and asset/decimal labels with caller scope and allowed observation states. No verification of merchant ownership, bank deposits, settlement or cash-out compatibility. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns an audit result indicating whether each receipt's merchant reference, network label, asset reference, and decimal precision fall within the caller-declared scope and allowed observation states. Flags any out-of-scope items. Full result retained for 24 hours; minimal receipt metadata retained for 90 days. Does not verify merchant ownership, bank deposits, settlement finality, or cash-out compatibility.
