# Provenance Manifests - Reference Integrity Map

> Provenance Manifests - Reference Integrity Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035113/call, status unknown (last checked 2026-10-16).

Validates parent existence and detects cycles within owner and subject frames of caller-supplied artifact and dataset provenance manifests, returning a reference integrity map.

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-reference-integrity-map-cd29e5ce -d '<json body>'
```

Example prompt: Check these 10 provenance manifest rows for parent existence issues and cycles in the owner and subject frames — the data is public and nonpersonal metadata only.

## When to prefer this

Use this endpoint when you need to structurally validate the reference graph of provenance manifests — specifically checking for missing parent nodes and cycles in owner/subject frames — without requiring source downloads, signature verification, or causal proof. It is appropriate for offline, typed, nonpersonal metadata validation of public or synthetic artifact and dataset provenance declarations.

## Known failure modes

- More than 32 rows submitted — exceeds maxItems limit
- nonpersonalMetadata not set to true — required constant
- Invalid or missing dataClass enum value (must be 'public' or 'synthetic')
- Malformed row structure causing parsing failure
- Service unavailable or timeout on large row batches

## How this service works

Check parent existence and cycles within owner and subject frames. Declared links do not prove causal execution or delegation authority 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 reference integrity map indicating which rows have valid parent references, which have missing parents, and which exhibit cycles within owner or subject frames. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days. No causal execution proof, signature verification, or source download is performed.
