How this service works
Weekday name from ISO date. Call when you label agent calendars without locale libs. Returns weekday and ok for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a JSON object containing the weekday name (e.g. 'Monday') corresponding to the provided ISO date, along with an 'ok' status field confirming the lookup succeeded.
Example use cases
Label calendar event with weekday
“I'm building a schedule and need to know what day of the week 2025-11-03 falls on — can you get the weekday name for that ISO date?”
Validate meeting date is a weekday
“We're planning a meeting for 2026-01-19 — can you tell me what day of the week that is so I can confirm it's not a weekend?”
Dynamic email greeting with weekday
“I want to personalize an email that goes out on 2025-08-12 — what weekday name corresponds to that ISO date so I can open with 'Happy Tuesday' or whatever applies?”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/weekday-nameWhen to prefer
Choose this endpoint when your agent needs to resolve a weekday name from an ISO date without importing locale libraries or date-formatting dependencies. It is ideal for lightweight calendar labeling, scheduling display, or personalization tasks in agent pipelines where simplicity and zero-dependency lookups matter. At $0.001 USDC per call it is cost-effective for per-event labeling.
Side effects
- Invalid or malformed ISO date string returns an error response
- Missing 'iso' field in request body causes a validation error
