# Quantum Hardware Configuration Snapshot Validator

> Quantum Hardware Configuration Snapshot Validator is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010072/call, status unknown (last checked 2026-10-15).

Compares supplied qubit, topology, gate-set, and configuration-revision declarations against a pinned snapshot digest offline, without querying live hardware.

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-hardware-configuration-snapshot-validator-51058325 -d '<json body>'
```

Example prompt: Check whether this quantum hardware configuration snapshot — including qubit count, topology, and gate-set declarations — matches the expected digest 'sha256:abc123' using only offline metadata, treating the data as public.

## When to prefer this

Choose this endpoint when you need to validate quantum hardware configuration declarations — qubits, topology, gate-set, configuration revision — against a known pinned digest without querying live hardware. It is best suited for offline audit, regression testing, or compliance verification workflows where only public or synthetic metadata is involved and no real-time hardware access or architecture ranking is required.

## Known failure modes

- Digest mismatch if supplied snapshot declarations deviate from the pinned reference
- Invalid or malformed snapshot object causing a parsing error
- Unsupported dataClass value outside 'public' or 'synthetic' enum
- Missing required nonpersonalMetadata flag or set to false
- Expired result retrieval beyond the 24-hour retention window
- Malformed expectedDigest string causing comparison failure

## How this service works

Compare supplied qubit, topology, gate-set and configuration-revision declarations with a pinned snapshot digest. No live hardware query or architecture ranking. Offline typed metadata only. Retained-result recovery: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns an offline comparison result indicating whether the supplied snapshot matches the expected digest, along with any detected discrepancies in qubit, topology, gate-set, or configuration-revision declarations. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
