# Quantum Circuit Records - Revision Delta Map

> Quantum Circuit Records - Revision Delta Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.02131/call, status unknown (last checked 2026-10-20).

Compares two snapshots of quantum circuit record collections (backend/circuit/register/operation-pin) and returns a structured map of owner, subject, revision, content, and scope-pin changes between them.

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-revision-delta-map-75513020 -d '<json body>'
```

Example prompt: Compare these two snapshots of my quantum circuit records — the before list has my old backend and register-pin entries, the after list has the updated ones — and give me a delta map showing exactly which record IDs changed owner, subject, revision, content, or scope pins. All data is public and nonpersonal metadata only.

## When to prefer this

Use this endpoint when you need a precise, field-level diff of quantum circuit metadata records (backend, circuit, register, or operation-pin) across two explicit snapshots identified by stable record IDs. Prefer it over general-purpose diff tools when working specifically with caller-supplied public or synthetic nonpersonal circuit metadata and needing enumerated delta reporting with 24-hour result retention. Not suitable for quantum simulation, device access, execution, calibration, or scientific circuit equivalence claims.

## Known failure modes

- Input payload exceeds 32 KiB limit — request rejected
- Arrays exceed 32 items each — validation error
- dataClass not set to 'public' or 'synthetic' — enum validation failure
- nonpersonalMetadata not set to true (const constraint) — rejected
- Mismatched or malformed record structures in before/after arrays — parsing error
- Network timeout or transient backend failure — retry required

## How this service works

Enumerate owner, subject, revision, content and scope pin changes by stable record ID in two supplied revisions for bounded backend/circuit/register/operation-pin records. 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

A structured delta map keyed by stable record IDs, listing which fields (owner, subject, revision, content, scope pin) changed between the before and after record arrays, scoped to backend/circuit/register/operation-pin record types. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days.
