## 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 publication-records-duplicate-identity-checker-d6903cbb -d '<json body>'
```

Example prompt: Check these 10 publication records for duplicate owner, subject, or revision declarations — they're public data with nonpersonal metadata only — and tell me which rows conflict with each other.

## When to prefer this

Use this endpoint when you need to detect duplicate or conflicting owner/subject/revision declarations within a bounded set of publication records (up to 32 rows) before ingestion, submission, or archiving. Best suited for pre-flight data quality checks on scientific publication datasets where you want record-level duplicate identity analysis without requiring independent certification. Prefer this over generic deduplication tools when the records involve scientific framing with owner, subject, and revision semantics.

## Known failure modes

- Fewer than 1 or more than 32 rows supplied — returns validation error
- nonpersonalMetadata not set to true — request rejected
- Invalid dataClass value outside 'public' or 'synthetic' enum — schema validation failure
- Malformed row objects in the array — parsing error returned
- Empty or null rows array — minimum items constraint violation

## How this service works

Compare duplicate owner/subject/revision declarations against every scientific frame Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an analysis of the supplied publication record rows identifying which entries contain duplicate or conflicting owner, subject, and revision declarations when compared across scientific frames; results are based on the caller-supplied data, not independent certification.
