## 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 ephemeris-snapshots-duplicate-record-identity-checker-fe982830 -d '<json body>'
```

Example prompt: Check these 10 ephemeris snapshot rows for duplicate owner, subject, or revision declarations — use the public data class and flag any identity conflicts across the scientific frames.

## When to prefer this

Use this endpoint when you need to detect duplicate owner, subject, or revision identity declarations within a bounded batch of ephemeris snapshot rows (up to 32) before ingestion or publication. It is purpose-built for celestial/scientific frame data and provides supplied-record analysis rather than authoritative certification. Prefer this over generic deduplication tools when your data is specifically structured as ephemeris snapshots with owner/subject/revision metadata.

## Known failure modes

- Fewer than 1 or more than 32 rows submitted returns a validation error
- Missing required nonpersonalMetadata: true flag causes rejection
- Invalid dataClass value (not 'public' or 'synthetic') returns schema error
- Malformed row objects cause parse failures
- Payment not included or insufficient USDC results in 402 response

## 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 a report identifying which submitted rows contain duplicate owner, subject, or revision declarations, cross-referenced against the scientific frame context. Does not provide independent certification — analysis is based solely on the supplied record set.
