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
Returns a JSON object with the currency code (ccy), the TTB (telegraphic transfer buying) rate, TTS (telegraphic transfer selling) rate, deal basis rate, the date of the rate, and the source (KEXIM). All rates are expressed in Korean won per unit of the requested currency.
Example use cases
USD to KRW rate for payment
“I need to send a USD payment to a Korean supplier — what's today's official KEXIM buying and selling rate for USD to Korean won?”
Historical KRW rate for accounting
“What was the official Korean won exchange rate for EUR on 2024-03-15? I need the TTB, TTS, and deal basis for our accounting records.”
JPY/KRW rate for import invoice
“Can you look up the current KEXIM exchange rate for Japanese yen against the Korean won? I need the deal basis rate for an import invoice.”
Technical details
Endpoint
GEThttps://x402.pokt-agent.com/kr-rates/fx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official, authoritative Korean won exchange rates sourced directly from KEXIM (Korea Eximbank), especially for cross-border trade, compliance, or financial reporting involving KRW. Prefer this over generic FX APIs when Korean regulatory or official rate accuracy matters, or when you need historical KRW rates for a specific date.
Side effects
- Missing or invalid 'ccy' parameter returns a validation error
- Unsupported currency codes not covered by KEXIM return no data or an error
- Requesting a date that falls on a Korean non-business day may return the nearest available rate or an error
- Payment failure via x402/USDC on Base results in 402 response and no data returned
- Future dates beyond available data return no results
