Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/time.diff-seconds--date-differenceWhen to prefer
Use this endpoint when you need a precise, programmatic second-level time difference between two dates within a paid micro-service workflow, especially when already integrated with the x402 payment protocol on PennyRail. It is ideal for lightweight temporal arithmetic where you want a hosted computation rather than implementing date math locally.
Side effects
- Invalid or unparseable date strings return an error response
- Missing required input fields cause a 400-level error
- Reversed date order may return a negative value or error depending on implementation
- Extremely distant date ranges may cause overflow or precision issues
- Payment failure (insufficient funds or x402 protocol error) prevents the call from completing
