Technical details
Endpoint
POSThttps://basic-utils-agent.up.railway.app/datetime/addWhen to prefer
Choose this endpoint when you need to compute a future date by adding a fixed number of days to a known base date — for example, calculating expiration dates, deadlines, or delivery windows. It is simple, fast, and stateless, making it ideal for scheduling logic within agentic workflows.
Side effects
- Invalid or malformed date string causes a 422 validation error
- Missing required 'date' or 'days' fields returns an error response
- Null values passed for both 'date' and 'days' with no fallback results in an error
- Non-integer value for 'days' fails schema validation
