# Optical Measurements - Duplicate Record Identity Comparison

> Optical Measurements - Duplicate Record Identity Comparison is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010323/call, status unknown (last checked 2026-10-17).

Compares duplicate owner, subject, and revision declarations across optical measurement scientific frames to identify conflicting or redundant record identities.

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 optical-measurements-duplicate-record-identity-comparison-0da9382e -d '<json body>'
```

Example prompt: Can you check these optical measurement records for duplicate owner, subject, and revision declarations? I have up to 20 rows of public data — flag any frames where the same owner/subject/revision combo appears more than once or conflicts across entries.

## When to prefer this

Choose this endpoint when you need to detect duplicate or conflicting owner/subject/revision identity declarations specifically within optical measurement scientific frames. It is purpose-built for optical measurement data deduplication, unlike general-purpose record deduplication tools. Best suited for pipelines where optical measurement data is ingested from multiple sources and identity collisions must be caught before downstream processing.

## Known failure modes

- Fewer than 1 or more than 32 rows provided — rejected by minItems/maxItems constraint
- dataClass not set to 'public' or 'synthetic' — enum validation failure
- nonpersonalMetadata not set to true (const constraint) — request rejected
- Malformed row objects causing schema validation errors
- Service unavailable or payment 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 an analysis of duplicate or conflicting owner, subject, and revision declarations found across the supplied optical measurement rows, identifying which frames share identical or contradictory identity pins. This is a supplied-record analysis and does not constitute independent certification.
