# Trial Registry Records Provenance Edge Audit - Provena

> Trial Registry Records Provenance Edge Audit - Provena is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.045333/call, status unknown (last checked 2026-10-16).

Audits declared graph edges by binding them to pinned endpoints and verified owner/subject nodes within trial registry record data, returning a supplier-analysis report (not independent certification).

## 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 trial-registry-records-provenance-edge-audit-provena-ed311100 -d '<json body>'
```

Example prompt: Audit the provenance edges in this trial registry graph — I have 5 nodes and 8 edges, all public data with nonpersonal metadata — and tell me which edges are correctly bound to their pinned endpoints and declared owner/subject nodes.

## When to prefer this

Choose this endpoint when you need a declared-graph provenance audit specifically for trial registry records, binding edges to pinned endpoints and owner/subject nodes, and you are working with public or synthetic (non-personal) data. Prefer this over generic graph validators when the domain is clinical trial registries and you need structured edge-binding analysis rather than simple cycle detection or hash validation.

## Known failure modes

- Exceeds maximum 32 edges or 32 nodes — request rejected with validation error
- nonpersonalMetadata not set to true — request refused
- dataClass not one of 'public' or 'synthetic' — schema validation failure
- Empty edges or nodes array (minItems:1 not met) — request rejected
- Malformed edge/node declarations — partial or error report returned
- Payment not received or insufficient USDC — 402 Payment Required

## How this service works

Bind a declared edge to both pinned endpoints and the exact owner/subject Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a supplier-side analysis report detailing which declared graph edges are correctly bound to their pinned endpoints and matched to the appropriate owner/subject nodes, along with findings on edge consistency — explicitly not an independent certification. Full contract details available at the describe URL.
