# Source Packs — Timestamp Order Audit

> Source Packs — Timestamp Order Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.015298/call, status unknown (last checked 2026-10-15).

Validates the temporal ordering of declared publication, observation, and expiry timestamps within source packs against a caller-supplied assessment time, using only offline typed non-personal metadata.

## 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 source-packs-timestamp-order-audit-bdaeff67 -d '<json body>'
```

Example prompt: Can you run a timestamp order audit on these 5 public source packs and check them against an assessment time of 2025-06-01T00:00:00Z — I need to know if any declared publication, observation, or expiry times are out of order or inconsistent?

## When to prefer this

Use this endpoint when you need to verify the temporal consistency of declared source pack metadata — specifically publication, observation, and expiry timestamps — against a specific reference time, without performing live source fetching or relying on a trusted server clock. Ideal for offline, deterministic audits of non-personal source metadata in compliance, data governance, or pre-ingestion validation workflows.

## Known failure modes

- Invalid or missing assessedAt timestamp causes rejection
- Source pack array exceeds maxItems limit of 32
- nonpersonalMetadata field not set to true (const constraint)
- Invalid dataClass value outside enum [public, synthetic]
- Malformed source entries cause validation failure
- Empty sources array (minItems 1 not met)

## How this service works

Inspect declared source publication, observation and expiry times at a caller-supplied assessment time. No source fetching, trusted clock or automatic freshness renewal. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns an audit report indicating whether the declared publication, observation, and expiry timestamps within the supplied source packs are in valid temporal order relative to the caller-supplied assessment time. Highlights any violations such as future-dated publications, expiry times preceding observation times, or other ordering anomalies. Result data is retained for 24 hours; minimal receipt metadata is kept for 90 days.
