## 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 package-manifests-reference-integrity-map-12b3ff1e -d '<json body>'
```

Example prompt: Can you check these 10 package manifest rows for missing parent references and cycles in their owner and subject fields? The data is synthetic and nonpersonal.

## When to prefer this

Use this endpoint when you need to validate reference integrity (missing parents, cycles) specifically within package manifest records, particularly owner and subject link chains. It is a fast, per-batch analytical check suited for pre-ingestion validation pipelines or data quality audits on supplied manifest datasets, not for live registry lookups or independent package certification.

## Known failure modes

- Rows array empty or exceeds 32-item limit — validation error
- nonpersonalMetadata not set to true — request rejected
- Invalid or missing dataClass enum value — schema validation failure
- Malformed row objects — partial or complete analysis failure
- Network timeout for large row batches

## 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

Returns a reference integrity map indicating which manifest rows have missing parent records (for owner or subject fields) and which contain cycles, along with relevant record identifiers. This is a supplied-record analysis, not independent certification.
