Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ceramic-measurements-duplicate-record-identity-check-1455dc2b -d '<json body>'
```

Example prompt: Check my ceramic measurement records for duplicate owner, subject, or revision declarations — I have up to 20 rows of public data and need to know which entries conflict across scientific frames.

## When to prefer this

Use this endpoint when you need to detect duplicate or conflicting owner, subject, or revision declarations specifically within ceramic measurement datasets. Choose it over general deduplication tools when you need comparison against scientific frames rather than simple field-level equality checks. Best suited for materials science workflows where up to 32 rows of public or synthetic ceramic data need quality screening before further analysis or submission.

## Known failure modes

- Exceeds 32-row limit — request rejected
- nonpersonalMetadata not set to true — request rejected
- Invalid dataClass value outside 'public' or 'synthetic' enum — validation error
- Empty rows array — minimum 1 row required
- Ambiguous revision declarations that cannot be resolved against scientific frames

## 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 comparison report identifying which rows have duplicate or conflicting owner, subject, and/or revision declarations relative to scientific frames; flags specific conflicts but does not independently certify the data.
