How this service works
Check declared issue/creation time, expiry and assessment time, including expiry equality and future timestamps; not an online freshness check for caller-supplied artifact and dataset provenance manifests. No source download, build reproduction, signature verification, proof of origin, causality or scientific validity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
Output
Returns an audit result per manifest row indicating whether declared timestamps (issue/creation time, expiry, assessedAt) are in valid logical order, flags any future-dated timestamps, identifies expiry equality violations, and notes any assessment time anomalies. Full results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
Example use cases
Dataset release timestamp consistency check
“I have 12 rows from our public dataset provenance manifest — can you check that none of the declared issue, expiry, and assessment timestamps are out of order or set in the future? It's all nonpersonal metadata, assessed as of today.”
Synthetic data manifest audit before publication
“Before we publish this synthetic dataset, can you run a timestamp order audit on these 8 provenance manifest rows to make sure expiry doesn't equal issue time and no assessment timestamps are future-dated?”
Provenance compliance pre-submission review
“We're submitting 20 public-class provenance manifest records — please validate that all declared creation times, expiry dates, and assessedAt values are logically consistent and flag any future timestamps or expiry equality violations.”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/verify/provenance-manifests/timestamp-order-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an offline, structured audit of declared timestamps within caller-supplied provenance manifests — specifically to validate logical ordering of issue, expiry, and assessment times, detect future timestamps, and check expiry equality. It is not suitable for online freshness checks, downloading source artifacts, verifying cryptographic signatures, or checking scientific validity. Prefer this over general-purpose validation tools when your data class is strictly public or synthetic nonpersonal metadata and you need a receipted audit trail.
Side effects
- Invalid or malformed timestamp strings cause parsing errors
- Rows array exceeds maxItems limit of 32, returning a 400 validation error
- Missing required nonpersonalMetadata field (must be true) causes rejection
- Invalid dataClass value outside enum [public, synthetic] causes 400 error
- Payment not supplied or insufficient USDC causes 402 response
- Rows array is empty (below minItems of 1) causes rejection
