# Payment Quotes - Scope Boundary Audit

> Payment Quotes - Scope Boundary Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.0383/call, status unknown (last checked 2026-10-16).

Compares payment quote metadata against an exact offer revision, resource, payee, and allowed network/asset/decimal scope to flag boundary mismatches — offline, nonpersonal metadata only.

## 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-scope-boundary-audit-700d57f0 -d '<json body>'
```

Example prompt: Can you run a scope boundary audit on these 3 payment quotes against offer revision 'rev-20240801-A', payee 'payee_0xabc123', asset 'USDC', 18 decimals, resource digest 'sha256:deadbeef', and allowed networks ['base', 'ethereum'] — data class is synthetic and metadata is nonpersonal?

## When to prefer this

Choose this endpoint when you need an offline, nonpersonal scope boundary audit of payment quote metadata against a specific offer revision, payee, asset, decimal precision, and allowed network set — without triggering any live payment authorization or merchant validation. Prefer it over live payment validators when you only need structural/scope compliance checking on quote metadata before submission.

## Known failure modes

- Missing required fields (quotes, offerId, revision, payeeRef, assetRef, allowedNetworks) return validation error
- nonpersonalMetadata not set to true causes rejection
- quotes array exceeds 32 items or is empty returns schema error
- decimals outside 0–18 range rejected
- allowedNetworks array exceeds 3 items returns error
- dataClass not 'public' or 'synthetic' causes enum validation failure
- Malformed resourceDigest or assetRef may return mismatch rather than error

## How this service works

Compare quote metadata with exact offer revision, resource, payee and allowed network/asset/decimal scope. A matching declaration does not validate the merchant or authorize payment. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a scope boundary comparison result indicating whether each quote's declared metadata (payee, asset, decimals, networks, resource digest) aligns with the supplied offer revision and allowed scope. Flags any boundary violations or mismatches. Does not validate the merchant, authorize payment, or fetch live data. Result retained for 24 hours; minimal receipt metadata retained for 90 days.
