# Neural Interface Records - Revision Delta Map

> Neural Interface Records - Revision Delta Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.021326/call, status unknown (last checked 2026-10-16).

Enumerates owner, subject, revision, content, and scope pin changes between two supplied revisions of a synthetic neural-interface model/calibration/pipeline record by stable record ID.

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-revision-delta-map-9aac751a -d '<json body>'
```

Example prompt: Show me what changed between these two revisions of the synthetic neural-interface calibration record — compare the before and after arrays I have and flag any owner, subject, content, or scope pin differences using the public data class.

## When to prefer this

Choose this endpoint when you need a structured field-level diff between exactly two revisions of a synthetic neural-interface model, calibration, or pipeline record — specifically to detect changes in owner, subject, revision, content, or scope pins. It is best suited for audit, compliance, or change-tracking workflows where you already have before and after revision snapshots and need a formal delta map rather than full record retrieval or certification.

## Known failure modes

- Invalid or mismatched record IDs between before and after arrays
- Arrays exceeding 32 items maximum limit
- dataClass not set to an accepted enum value (public or synthetic)
- nonpersonalMetadata not set to the required const value of true
- Empty or malformed revision arrays causing no delta to be computed
- Record not found for supplied stable ID
- Payment failure via x402 protocol

## How this service works

Enumerate owner, subject, revision, content and scope pin changes by stable record ID in two supplied revisions for synthetic neural-interface model/calibration/pipeline Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured delta map enumerating all changes — including owner, subject, revision, content, and scope pin differences — between the two supplied revision states of a synthetic neural-interface model, calibration, or pipeline record. Analysis is supplied-record only and does not constitute independent certification.
