# Ceramic Measurements - Timestamp Order Audit

> Ceramic Measurements - Timestamp Order Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.015321/call, status unknown (last checked 2026-10-16).

Validates the chronological order and maximum age of collection, processing, and export timestamps in ceramic measurement records, flagging out-of-order or stale entries.

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 ceramic-measurements-timestamp-order-audit-c4b8bffd -d '<json body>'
```

Example prompt: Can you audit these 15 ceramic measurement records — they're public data — and check that collection, processing, and export timestamps are in the right order and none are older than 7 days (604800 seconds)? The assessment is as of now.

## When to prefer this

Use this endpoint when you need to audit the chronological ordering and age compliance of ceramic measurement records specifically, where the pipeline has distinct collection, processing, and export stages. Prefer this over generic timestamp validation tools when working with ceramic materials data that must pass ordering checks before downstream use. Not a substitute for independent certification — best suited for self-service record analysis of public or synthetic ceramic datasets.

## Known failure modes

- Rows array empty or exceeds 32 items — validation error returned
- maximumAgeSeconds out of range (below 0 or above 31536000) — rejected with schema error
- assessedAt not a valid timestamp string — parsing error
- dataClass not one of 'public' or 'synthetic' — enum validation failure
- nonpersonalMetadata not set to true — rejected due to const constraint
- Missing required fields in individual rows — partial or error result

## How this service works

Check collection/processing/export order and caller-defined maximum age; absent processing or export timestamps stay unknown, and equal timestamps are allowed for ceramic measurement Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an audit result indicating whether each row's collection, processing, and export timestamps are in the correct chronological order, which timestamps are absent or unknown, whether any records exceed the caller-defined maximum age in seconds, and a summary of any ordering or staleness violations found. Does not certify the data independently — only analyzes the supplied records.
