Example use cases
Korea trade deadline scheduling
“We need to schedule a payment to our Korean supplier by their deadline — can you check if November 3, 2025 is actually a business day in South Korea or if we need to move it?”
Korean market hours planning
“I'm setting up automated trades on the Korean stock exchange — is December 25, 2025 a business day there, or is it a holiday?”
Substitute holiday detection for contracts
“Our contract with a Seoul firm says delivery is due on October 5, 2026 — is that a real Korean business day or a substitute public holiday?”
Technical details
Endpoint
GEThttps://x402.pokt-agent.com/kr-calendar/day?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative Korean public holiday and business-day data for a specific date, especially for scheduling payments, contracts, or financial operations involving Korean counterparties. Prefer this over generic calendar APIs when Korean substitute holidays (대체공휴일) or Korean-language holiday names are required.
Side effects
- Missing or malformed date query parameter returns an error
- Dates outside supported range may return unexpected results or errors
- Non-ISO date formats (e.g. MM/DD/YYYY) may cause parse failures
- Payment failure over x402/USDC Base network blocks the call
