## 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 grant-records-reference-integrity-map-c8dc0ca7 -d '<json body>'
```

Example prompt: Can you check these 10 grant records for broken parent references or ownership cycles? They're public data and contain no personal metadata — I need a reference integrity map to know which rows have missing parents or circular links.

## When to prefer this

Use this endpoint when you have a bounded batch of up to 32 grant records and need to verify their internal reference structure — specifically parent existence and cycle detection in owner/subject chains — before ingestion, auditing, or downstream processing. Prefer this over general data validation tools when the concern is specifically grant record parent-child hierarchy integrity.

## Known failure modes

- Exceeds 32-row limit — request rejected with validation error
- nonpersonalMetadata not set to true — request rejected
- Invalid dataClass value outside enum ['public','synthetic'] — request rejected
- Malformed row objects missing required fields — partial or full analysis failure
- Cycles that span records outside the supplied batch will not be detected

## How this service works

Check parent existence and cycles within owner and subject Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

A reference integrity map identifying which rows have missing parent records, which have cyclic references within owner or subject chains, and any cross-reference anomalies — scoped to the supplied rows only, not an independent certification.
