# Quantum Circuit Records - Duplicate Identity Detector

> Quantum Circuit Records - Duplicate Identity Detector is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.01031/call, status unknown (last checked 2026-10-20).

Groups quantum circuit/backend/revision frames and distinguishes exact pinned duplicates from conflicts in operation digest, register size, or scope.

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 quantum-circuit-records-duplicate-identity-detector-8f3ac357 -d '<json body>'
```

Example prompt: Can you check these 10 quantum circuit frame records and tell me which ones are exact pinned duplicates versus which ones conflict on operation digest, register size, or scope? The data is public and nonpersonal.

## When to prefer this

Choose this endpoint when you need to classify a batch of quantum circuit or backend frame records as true exact duplicates versus conflicting records based on operation digest, register size, or scope — not for simulation, execution, or equivalence checking. Useful for deduplication pipelines, ingestion audits, and metadata integrity checks on public or synthetic nonpersonal circuit metadata.

## Known failure modes

- Input exceeds 32 KiB limit — request rejected
- rows array empty or exceeds 32 items — validation error
- nonpersonalMetadata not set to true — request rejected
- dataClass not one of 'public' or 'synthetic' — validation error
- Payment not provided or insufficient — 402 response
- Malformed row structure — processing error

## How this service works

Group circuit/backend/revision frames and distinguish exact pinned duplicates from conflicts in operation digest, register size or scope. Ingestion IDs are not circuit identity. Caller-supplied public/synthetic nonpersonal metadata only. No quantum simulation, device/API access, execution, calibration measurement, scientific validation or claim of circuit equivalence. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns grouped circuit/backend/revision frame records classified as either exact pinned duplicates or conflict entries, with conflict reasons including operation digest mismatches, register size differences, or scope differences. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
