# Trial Registry Records - Duplicate Record Identity Checker

> Trial Registry Records - Duplicate Record Identity Checker is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010333/call, status unknown (last checked 2026-10-16).

Compares duplicate owner, subject, and revision declarations in trial registry record rows against scientific frame constraints to detect conflicting or redundant entries.

## 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 trial-registry-records-duplicate-record-identity-checker-8d783ffd -d '<json body>'
```

Example prompt: Check these 10 trial registry record rows for duplicate owner, subject, and revision declarations — the data is synthetic — and flag any that conflict across scientific frames.

## When to prefer this

Use this endpoint when you need to detect duplicate or conflicting owner/subject/revision declarations within a batch of trial registry records (up to 32 rows) before submission or during data quality audits. It is specifically designed for scientific record deduplication across declared frame constraints, not general-purpose deduplication or database diffing. Prefer this over generic validation tools when your data involves trial registry metadata with owner, subject, and revision dimensions.

## Known failure modes

- More than 32 rows submitted — maxItems limit exceeded
- Missing or invalid dataClass enum value (must be 'public' or 'synthetic')
- nonpersonalMetadata not set to true — required constant field
- Empty rows array — minItems of 1 not met
- Malformed row objects that don't conform to expected scientific frame structure
- Network or payment authorization failure via x402 protocol

## 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 analysis of the submitted record rows, identifying which rows contain duplicate or conflicting owner, subject, and/or revision declarations relative to every scientific frame constraint. Results are advisory (supplied-record analysis, not independent certification) and include frame-level conflict flags.
