How this service works
Check declared HTTP contract publication/retirement times against a supplied assessment. Missing retirement stays open-ended; no freshness, availability or execution certification. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
Output
Returns a timestamp order audit report indicating whether each contract's publication and retirement times are in correct chronological sequence relative to the supplied assessment timestamp. Flags contracts with missing retirement dates as open-ended. No live availability or freshness data is certified. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days.
Example use cases
Pre-deployment API contract validation
“I have a batch of 5 API contracts we're about to publish — can you verify that all the publication and retirement timestamps are in valid chronological order as of today, 2025-06-01T00:00:00Z? They're all public metadata, no personal data involved.”
Compliance audit of historical API lifecycle
“We need to audit our legacy API contracts to confirm their declared publication and retirement times are sequentially consistent. The assessment date is 2024-09-30T00:00:00Z and these are synthetic test contracts — can you flag any where retirement precedes publication or retirement is missing?”
Detecting open-ended contracts in contract registry
“Can you check this set of 10 public API contracts and tell me which ones have no declared retirement time, and whether the publication timestamps all come before my assessment point of 2025-01-01T00:00:00Z?”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/verify/api-contracts/timestamp-order-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, offline, typed audit of API contract timestamp sequencing — specifically to confirm publication precedes retirement and to surface open-ended (no retirement declared) contracts. Prefer it over general contract validators when you need deterministic chronological ordering checks on nonpersonal metadata without side effects or live freshness certification.
Side effects
- Missing or malformed assessedAt timestamp causes validation failure
- Contracts array exceeds 32-item limit returns error
- dataClass value outside enum (public/synthetic) is rejected
- nonpersonalMetadata not set to true (const) causes schema rejection
- Contracts with incomplete timestamp fields may yield partial audit results
