How this service works
Add a fixed duration (days/hours/minutes/seconds) to an ISO 8601 datetime.
Output
Returns the resulting ISO 8601 datetime after adding the specified number of days, hours, minutes, and seconds to the input datetime. The output is a shifted timestamp reflecting the exact duration added.
Example use cases
Calculate task deadline from start time
“My task starts at 2025-07-01T08:00:00Z and is due 3 days and 4 hours later — what's the exact deadline datetime?”
Schedule a meeting 90 minutes from now
“It's 2025-06-20T14:00:00Z right now — what time will it be in 1 hour and 30 minutes?”
Compute token expiry time
“If a session token was issued at 2025-06-18T00:00:00Z, what datetime does it expire after 7 days?”
Technical details
Endpoint
GEThttps://x402.agentindex.world/time/add?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to arithmetically shift a known ISO 8601 datetime forward by a fixed duration composed of days, hours, minutes, and/or seconds — especially in agent workflows where datetime math must be offloaded as a reliable utility call. Prefer this over client-side computation when you want a consistent, stateless, pay-per-call service without implementing datetime libraries.
Side effects
- Missing or malformed datetime input (not valid ISO 8601) results in an error response
- Non-integer values for days/hours/minutes/seconds may be rejected
- Extremely large duration values may cause overflow errors
- Payment failure (x402 protocol) prevents the call from completing
