# Quantum Calibrations - Record Sequence Diff

> Quantum Calibrations - Record Sequence Diff is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.03514/call, status unknown (last checked 2026-10-20).

Separates record insertions/deletions from reordering changes within bounded quantum calibration record sequences, operating only on caller-supplied public or synthetic nonpersonal calibration data.

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-calibrations-record-sequence-diff-c9064cbd -d '<json body>'
```

Example prompt: Compare these two lists of quantum calibration records — the before list has 5 entries and the after list has 6 — and tell me which changes are actual insertions or deletions versus just records being reordered; the data is synthetic and nonpersonal.

## When to prefer this

Choose this endpoint when you need to precisely distinguish whether changes between two versions of a calibration record list are due to insertions/deletions versus mere reordering of surviving records, and your data is strictly public or synthetic nonpersonal calibration declarations. It is not suitable for hardware measurement, live device data, personal data, or scientific certification needs.

## Known failure modes

- Input arrays exceed 32-item limit — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true — request rejected
- Payload exceeds 32 KiB input limit — request rejected
- Results expired after 24 hours — result no longer retrievable

## How this service works

Separate record changes from shared-record reordering; inserting or deleting a record does not itself reorder surviving records for bounded backend/run/register/measurement-pin records. Caller-supplied public/synthetic nonpersonal calibration declarations only. No hardware measurement, device/API access, recalibration, mitigation, performance guarantee or scientific certification. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

A structured diff output that distinguishes record insertions and deletions from sequence reorderings among surviving records in bounded backend/run/register/measurement-pin calibration records, covering only caller-supplied public or synthetic nonpersonal calibration declarations. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
