How this service works
Pay-per-call Korean company due diligence, company ID crosswalk, sanctions screening with Korean name variants, Upbit/Bithumb risk events, HWP to Markdown, business status, business-day calendar, address normalisation, law, rates, filings and more. No account or API key: pay each call in USDC on Base via x402.
Output
A JSON object containing: the requested offset n, the start date, the computed result date (YYYY-MM-DD), and an array of holidays_skipped listing any Korean public holidays (with Korean names) that were bypassed in the calculation.
Example use cases
Contract payment due date
“Our Korean supplier contract says payment is due 10 Korean business days after September 23 2026 — what's the actual calendar date, accounting for Chuseok and any other public holidays?”
Settlement date for Korean securities trade
“I need the Korean business day that is 2 working days after 2025-01-29 for a T+2 securities settlement — make sure to skip any Korean public holidays.”
Deadline back-calculation for legal filing
“A Korean regulatory deadline is 3 business days before 2026-10-05. What date does that land on once Korean holidays are factored out?”
Technical details
Endpoint
GEThttps://x402.pokt-agent.com/kr-calendar/add?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compute a future or past Korean business date relative to a given start date, specifically accounting for Korean public holidays (e.g. Chuseok, Seollal, national holidays). Prefer this over generic business-day calculators when Korean holiday accuracy is critical — e.g. for Korean legal deadlines, financial settlement dates, or supplier contract terms. It requires no API key and charges $0.005 USDC per call via the x402 protocol on Base.
Side effects
- Missing required query parameter 'date' or 'n' returns a validation error
- Malformed date format (not YYYY-MM-DD) causes a parse error
- Non-integer value for n causes a validation error
- Payment failure via x402/USDC results in 402 response and no data returned
- Dates far in the future may not have holiday data populated, returning incomplete results
