Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/next-weekdayWhen to prefer
Use this endpoint when an agent needs to deterministically find the next occurrence of a specific day of the week from a given date — for example, scheduling recurring meetings, computing deployment windows, or anchoring deadlines to weekdays. It requires no API key, no subscription, and validation errors are not billed, making it safe to call with uncertain inputs.
Side effects
- Invalid or unparseable date format returns a structured validation error (not billed)
- Missing or unrecognized weekday value returns a validation error
- Malformed ISO-8601 timestamp triggers an error response without charge
