How this service works
Check supplied quote issue and expiry times at an explicit assessment time, using an exclusive expiry boundary. No trusted clock, issuer authentication or auto-renewal. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
Output
Returns a timestamp order audit result for each supplied quote, indicating whether issue and expiry times are correctly ordered relative to the provided assessment time using an exclusive expiry boundary. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days. No trusted clock or issuer authentication is applied.
Example use cases
Pre-settlement quote validity check
“I have a batch of 10 payment quotes and need to verify their issue and expiry timestamps are in the right order as of right now — treat the data as public and use the exclusive expiry boundary.”
Offline audit of synthetic test quotes
“Run a timestamp order audit on these synthetic payment quotes assessed at 2025-07-15T09:00:00Z and tell me which ones fail the exclusive expiry boundary check.”
Compliance review of quote metadata timing
“I need to audit these 5 payment quotes to confirm their issue times come before their expiry times, evaluated as of 2025-05-20T00:00:00Z — the data is public and nonpersonal only.”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/verify/payment-quotes/timestamp-order-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an offline, stateless audit of payment quote timestamp ordering against a specific assessment time, without relying on a trusted clock or issuer authentication. Prefer it for public or synthetic (non-personal) quote metadata validation where the exclusive expiry boundary semantics are required and auto-renewal is not needed.
Side effects
- Invalid or unparseable assessedAt timestamp returns a validation error
- Quotes array exceeds 32 items triggers a schema rejection
- nonpersonalMetadata not set to true causes request rejection
- Malformed quote objects in the array may result in per-quote audit errors or overall failure
- Assessment time outside plausible range may return unexpected ordering results
