## 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 scientific-dataset-records-timestamp-order-audit-3039c857 -d '<json body>'
```

Example prompt: Can you audit the timestamp ordering for dataset revision 'v2.3' in repository 'geo-climate-001', checking that the publication instant '2024-01-15T00:00:00Z', amendment instant '2024-03-10T00:00:00Z', and availability window '2024-01-15T00:00:00Z' to '2024-06-01T00:00:00Z' are all consistent with an assessment instant of '2025-01-01T00:00:00Z', using public data class?

## When to prefer this

Use this endpoint when you need to programmatically verify the temporal integrity of scientific dataset records — specifically that publication, amendment, and availability window timestamps are logically ordered against an assessment instant within a known issuer/record/source/revision context. Prefer this over general-purpose timestamp utilities when working with scientific dataset provenance metadata that includes half-open availability windows and explicit revision tracking.

## Known failure modes

- Invalid or unparseable timestamp strings return a validation error
- Assessment instant falls outside the declared availability window — flagged as inconsistent
- Amendment instant precedes publication instant — returned as ordering violation
- Missing required fields such as assessedAt or datasetRef result in schema validation failure
- More than 32 rows submitted returns a maxItems constraint error
- dataClass value outside allowed enum returns a type error

## How this service works

Compare supplied publication/amendment instants and an explicit half-open availability window against one assessment instant, in an identical issuer/record/source/revision Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an audit result indicating whether the supplied publication instant, amendment instant, and half-open availability window are temporally consistent with the provided assessment instant for the matched dataset record — confirming correct ordering (publication before amendment, both within the availability window, relative to the assessment point) without independently certifying the data.
