Output
A UTC ISO 8601 timestamp string representing the computed date and time after applying the specified duration offset to the base date.

Technical details
Endpoint
POSThttps://agent402.tools/api/add-timeWhen to prefer
Use this endpoint when you need to arithmetically offset a date or time by a human-friendly duration string (e.g. '2d', '-3h', '1w 2d', '90m') and get back a precise UTC ISO timestamp. Prefer this over manual date math or building duration parsers yourself, especially for agents handling scheduling, expiry calculations, or relative time offsets.
Side effects
- Invalid or unrecognized duration format returns an error (e.g. '2x' or empty string)
- Malformed base date string causes a parse error
- Missing duration parameter results in a validation error
- Negative duration that produces a date before Unix epoch may cause issues
