## 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 bibliographies-duplicate-record-identities-fb5d814f -d '<json body>'
```

Example prompt: Can you check these 10 bibliography records for duplicate identities across sources and jurisdictions? They're all public data and contain no personal metadata — group any records that appear to be the same entity declared under different identities.

## When to prefer this

Choose this endpoint when you need to detect and group duplicate record identities across multiple declared sources, jurisdictions, or record kinds within a bibliographic or organizational records context. It is particularly useful for deduplication pipelines, publication pre-checks, and compliance audits where records may have been declared under different names or revisions across different systems. Note that this is a supplied-record analysis service, not an independent certification authority.

## Known failure modes

- Fewer than 1 or more than 32 rows submitted returns a validation error
- dataClass not set to 'public' or 'synthetic' causes rejection
- nonpersonalMetadata not set to boolean true causes rejection
- Malformed or missing row data results in parse errors
- Payment failure or insufficient USDC balance blocks the request

## 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 grouped duplicate identity clusters across the submitted record rows, with comparisons spanning each source, jurisdiction, record kind, and content dimension. The analysis identifies which declared identities match or conflict, without independently certifying any record — it reflects supplied-record analysis only.
