# Neural Interface Records - Record Sequence Diff

> Neural Interface Records - Record Sequence Diff is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.03523/call, status unknown (last checked 2026-10-25).

Computes the difference between two sequences of neural-interface model/calibration/pipeline records, separating true record insertions/deletions from reordering of surviving records.

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 neural-interface-records-record-sequence-diff-a81b6824 -d '<json body>'
```

Example prompt: Compare these two arrays of synthetic neural-interface calibration records and tell me which records were actually inserted or deleted versus just reordered — before has 5 entries and after has 6, all nonpersonal metadata only.

## When to prefer this

Choose this endpoint when you need to distinguish genuine record insertions and deletions from mere reordering of surviving records in neural-interface model, calibration, or pipeline datasets. It is specifically designed for the neural-interface domain with synthetic/public data classification and enforces nonpersonal metadata constraints, making it appropriate for privacy-safe analysis of up to 32-record sequences.

## Known failure modes

- Arrays exceed 32-item limit — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true (const) — request rejected
- Malformed or empty arrays with incompatible types — schema validation failure
- Payment not provided or insufficient USDC — 402 Payment Required

## How this service works

Separate record changes from shared-record reordering; inserting or deleting a record does not itself reorder surviving records for synthetic neural-interface model/calibration/pipeline Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

A structured diff indicating which records were inserted, which were deleted, and which surviving records were merely reordered, so callers can distinguish true record-set changes from sequence permutations in neural-interface model/calibration/pipeline data.
