# Ecology Observations Timestamp Order Audit

> Ecology Observations Timestamp Order Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.015315/call, status unknown (last checked 2026-10-16).

Validates that ecology observation records appear in correct collection, processing, and export timestamp order and checks that records fall within a caller-defined maximum age window.

## 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 ecology-observations-timestamp-order-audit-1f02dab4 -d '<json body>'
```

Example prompt: Can you audit the timestamp ordering for these 15 ecology observation rows — the data class is 'public', they were assessed today, and I want to flag anything older than 7 days (604800 seconds)? I need to confirm collection timestamps come before processing and export timestamps.

## When to prefer this

Use this endpoint when you need to programmatically validate the temporal ordering and age of ecology observation records before ingestion, publication, or export — particularly when you need nuanced handling of absent timestamps (treated as unknown rather than errors) and need to allow equal timestamps. Best suited for ecology-domain data quality pipelines rather than general-purpose timestamp validation.

## Known failure modes

- Invalid or missing 'rows' array (must have 1–32 items)
- dataClass not one of 'public' or 'synthetic'
- maximumAgeSeconds out of range (must be 0–31536000)
- nonpersonalMetadata not set to true (const constraint)
- Malformed assessedAt timestamp string
- Empty or null row data causing parsing errors

## 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 ecology observation export Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an audit report indicating whether the supplied ecology observation rows are in valid timestamp order (collection → processing → export) and whether they fall within the specified maximum age window. Flags any rows with ordering violations or age violations. Notes that absent processing or export timestamps remain unknown rather than flagged, and equal timestamps are permitted.
