How this service works
Machine-readable settlement service
Output
Returns a numeric value representing the absolute or signed difference in seconds between the two provided timestamps, along with any supporting metadata the service includes in its response object.
Example use cases
Measure API response duration
“I have a start time of 2024-11-15T14:00:00Z and an end time of 2024-11-15T14:00:04.732Z — how many seconds did that operation take?”
Calculate age of a log entry
“A log event was recorded at 2024-01-01T00:00:00Z and the current time is 2024-07-15T12:00:00Z — how many seconds ago was that?”
Check SLA breach window
“My SLA window opened at 2024-12-01T09:00:00Z and closed at 2024-12-01T09:15:30Z — how many seconds was that window open?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/time.diff-seconds--time-differenceWhen to prefer
Use this endpoint when you need a simple, metered computation of the elapsed seconds between two timestamps without building the arithmetic yourself, especially in agent workflows that already support x402 micropayment protocols. It is ideal for pay-per-use pipelines where you want deterministic, machine-readable time differences without spinning up local date libraries.
Side effects
- Missing or malformed input timestamps result in an error response
- Invalid datetime format not parseable by the service returns an error
- Network or payment authorization failure (x402) results in a 402 Payment Required response
- Reversed or ambiguous timestamp pairs may return negative values or an error
