## 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-duplicate-record-identity-comparison-16712172 -d '<json body>'
```

Example prompt: I have up to 32 rows of public grant records from multiple sources and jurisdictions — can you group them by declared organization and revision identity and flag any duplicates across those sources and record kinds?

## When to prefer this

Choose this endpoint when you need to detect and group duplicate grant records across multiple data sources, jurisdictions, or record-kinds based on declared organizational and revision identities. Prefer it over generic deduplication tools when the records are specifically grant-domain data and you need structured cross-source identity comparison rather than fuzzy string matching. Not a substitute for independent certification or authoritative record lookup.

## Known failure modes

- Rows array exceeds 32 items — request rejected
- Rows array is empty (minItems:1 not met) — validation error
- dataClass not set to 'public' or 'synthetic' — enum validation failure
- nonpersonalMetadata not set to true (const constraint) — request rejected
- Malformed row objects that cannot be parsed for identity fields — partial or failed grouping
- Network or payment failure returns HTTP 402 if x402 payment not completed

## 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 identity clusters of the supplied grant record rows, with comparisons across every source, jurisdiction, record-kind, and content dimension. Indicates which records share declared identities and flags duplicates. Does not provide independent certification — analysis is based solely on the supplied data.
