# Catalyst Measurements - Scope Boundary Audit

> Catalyst Measurements - Scope Boundary Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.038318/call, status unknown (last checked 2026-10-20).

Validates that catalyst measurement records conform to declared owner, subject, revision, and allowed scope labels, flagging any scope violations for public material-lot or method-pinned records.

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 catalyst-measurements-scope-boundary-audit-27af24cd -d '<json body>'
```

Example prompt: Run a scope boundary audit on these 10 catalyst measurement rows for owner 'org-42', subject 'cat-batch-7', revision 'r3', with allowed scopes ['internal','lab-review'] and dataClass 'public' — flag any rows that fall outside those scope labels.

## When to prefer this

Use this endpoint when you need to enforce governance rules on catalyst measurement records — specifically to verify that rows respect declared owner, subject, revision, and scope label constraints for public or synthetic material-lot or method-pinned data. Prefer this over general data validation tools when the domain is catalyst or material measurement compliance and scope boundary auditing is the primary concern.

## Known failure modes

- Missing required ownerRef or subjectRef causes validation rejection
- rows array empty or exceeds 32-item limit returns schema error
- dataClass value outside 'public' or 'synthetic' enum rejected
- allowedScopes array empty or exceeds 16-item limit returns error
- nonpersonalMetadata not set to true (const) causes rejection
- Revision string mismatch results in audit failure or unresolvable record
- Malformed row objects return parsing errors

## How this service works

Enforce exact declared owner, subject, revision and allowed scope labels; a matching label grants no permission or access for public material-lot/method-pinned catalyst measurement Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured audit report indicating which submitted measurement rows comply with or violate the declared owner, subject, revision, and allowed scope label constraints, without granting access to the underlying material or method data.
