Endpoint
POSThttps://jp-calendar-x402.onrender.com/v1/add-business-daysWhen to prefer
Use this endpoint when you need to compute a future date by adding a specific number of working days in Japan, accounting for both weekends and Japanese national public holidays. Ideal for due date calculations, invoice payment terms, shipping ETAs, or any Japan-specific business calendar arithmetic for dates within 2026-2027.
Side effects
- Date outside supported range (2026-2027) — endpoint may return an error or unsupported response
- Invalid date format supplied (non-YYYY-MM-DD) — likely 4xx parse error
- Negative or zero business days requested — behavior undefined
- Payment not submitted or USDC balance insufficient — 402 Payment Required
- Render cold-start latency if service is idle — slow first response
