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 array of rate items, each containing a date string, a numeric rate value (e.g. 1380.5), a series identifier (e.g. 'USDKRW'), and the source institution (e.g. 'KEXIM'). Suitable for use in financial calculations, compliance documentation, or FX conversion.
Example use cases
Invoice conversion for Korean vendor
“I need to convert a KRW invoice amount to USD — what was the official USDKRW exchange rate from KEXIM on March 15, 2025?”
Historical FX rate for accounting close
“Our finance team needs the USD/KRW rate for December 31, 2024 for year-end accounting — can you pull the official Korean rate for that date?”
FX compliance rate for Korea remittance
“We sent a wire to a Korean supplier on January 8, 2025 and need the official KEXIM exchange rate for that day to document in our compliance records.”

Endpoint
POSThttps://x402.pokt-agent.com/kr-rates/query?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official Korean exchange rates (especially USDKRW from KEXIM) for a specific date, whether for invoicing, accounting, compliance, or FX conversion. Prefer this over generic FX APIs when Korean regulatory or institutional sourcing is required, or when you need historical rates aligned with Korean business-day calendars. The x402 micropayment model means no API key or account setup is needed.
Side effects
- Date falls on a Korean public holiday or non-business day — no rate available for that date
- Unsupported currency pair or rate series — empty or error response
- Ambiguous natural language question — may return unexpected series
- Payment failure via x402/USDC — call rejected before processing
- Date in the future beyond available forward data — no result
