## 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 market-catalogues-duplicate-record-identity-analysis-b3e50390 -d '<json body>'
```

Example prompt: I have up to 32 rows of public market catalogue records and I need you to group and compare all their organization and record identities to find any duplicates across sources, jurisdictions, and record kinds — treat the metadata as nonpersonal.

## When to prefer this

Choose this endpoint when you have up to 32 market catalogue rows and need to detect duplicate identities across multiple sources, jurisdictions, or record kinds within that supplied dataset. It is best suited for data-quality checks on catalogue batches where you control the input and only need analysis of what you provide, not external verification or certification. Prefer alternatives if you need cross-database external lookups, entity resolution against third-party registries, or large-batch processing beyond 32 rows.

## Known failure modes

- Fewer than 1 or more than 32 rows submitted — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not explicitly set to true — request rejected
- Malformed row objects that cannot be parsed for identity fields
- Ambiguous or missing identity fields in rows leading to incomplete grouping

## How this service works

Group declared organization/record/revision identities and compare every source, jurisdiction, record-kind and content Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a grouped analysis of declared organization, record, and revision identities across all supplied rows, highlighting duplicates, cross-source conflicts, jurisdiction overlaps, and record-kind comparisons. This is a supplied-record analysis only, not independent certification.
