Technical details
Endpoint
POSThttps://agent402.tools/api/ageWhen to prefer
Use this endpoint when you need a precise, decomposed age (years + months + days) rather than just a year difference, or when you need total days elapsed since birth. Prefer this over generic date-diff tools when the output must be in human-readable age format suitable for displaying a person's age.
Side effects
- Invalid or unparseable birthdate format returns an error
- Future birthdate (birthdate after reference date) may return an error or zero/negative result
- Missing birthdate field causes a validation error
- Malformed JSON body returns a 400 bad request
