# Provenance Manifests - Revision Delta Map

> Provenance Manifests - Revision Delta Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.021307/call, status unknown (last checked 2026-10-20).

Enumerates changes in owner, subject, revision, content, and scope pins between two supplied provenance manifest snapshots, identified by stable record IDs.

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 provenance-manifests-revision-delta-map-6dc92144 -d '<json body>'
```

Example prompt: Compare my two artifact provenance manifests — the 'before' list has these 5 record entries and the 'after' list has the updated 5 — and give me a delta map showing which record IDs changed their owner, subject, revision, content, or scope pins. Data class is public and this is nonpersonal metadata only.

## When to prefer this

Choose this endpoint when you need a structured, offline enumeration of which provenance metadata fields changed between two discrete manifest snapshots identified by stable record IDs — particularly for artifact or dataset governance workflows. It is not suitable when you need source downloads, build reproduction, cryptographic signature verification, proof of origin, or persistence beyond 24 hours.

## Known failure modes

- Exceeds maxItems of 32 for before or after arrays — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true (const) — request rejected
- Malformed or missing record structures in before/after arrays — parsing error
- Result unavailable after 24-hour retention window

## How this service works

Enumerate owner, subject, revision, content and scope pin changes by stable record ID in two supplied revisions for caller-supplied artifact and dataset provenance manifests. No source download, build reproduction, signature verification, proof of origin, causality or scientific validity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

A delta map keyed by stable record ID listing which provenance manifest records changed between the before and after arrays, with per-record breakdowns of which pins (owner, subject, revision, content, scope) differed. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days. No source download, build reproduction, signature verification, or proof of origin is performed.
