# Protein Measurements - Duplicate Record Identity Comparator

> Protein Measurements - Duplicate Record Identity Comparator is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010314/call, status unknown (last checked 2026-10-16).

Compares duplicate owner, subject, and revision declarations in protein measurement metadata records against scientific frame pins to detect identity conflicts.

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 protein-measurements-duplicate-record-identity-comparator-ac3c2501 -d '<json body>'
```

Example prompt: Check these protein measurement rows for duplicate owner and subject declarations against the scientific frame pins — the data is synthetic nonpersonal metadata, so flag any identity conflicts across revisions.

## When to prefer this

Choose this endpoint when you need to detect duplicate identity declarations (owner, subject, revision) in protein measurement metadata records specifically against scientific frame pins. It is scoped strictly to public or synthetic nonpersonal metadata and is not suitable for clinical, genomic, or patient data. Prefer this over generic deduplication tools when the context involves scientific frame pin validation in a bioinformatics or protein research metadata pipeline.

## Known failure modes

- Input exceeds 32 KiB limit — request rejected
- More than 32 rows submitted — validation error
- dataClass not set to 'public' or 'synthetic' — enum validation failure
- nonpersonal metadata flag not set to true — request rejected
- Patient or individual genomic data detected — policy rejection
- Malformed row objects — schema validation error

## How this service works

Compare duplicate owner/subject/revision declarations against every scientific frame pin. Public or synthetic nonpersonal metadata only; no patient or individual genomic records, raw sequences, diagnosis, clinical interpretation, experimental instructions, source download or scientific-validity certification. Supplied digests are pins, not verified bytes. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a comparison result indicating which rows contain duplicate owner, subject, or revision declarations conflicting with scientific frame pins, along with receipt metadata retained for 90 days and result data retained for 24 hours.
