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 a total count and a results array. Each result contains the standardised Korean road address (road_address), an English transliteration (english), and the postal code (postal_code).
Example use cases
Shipping label address validation
“I need to send a package to '세종대로 209 종로구' in Seoul — can you find the official normalised road address and postal code so I can fill out the shipping label correctly?”
KYC address verification for Korean customer
“We have a Korean customer who listed their address as '종로구 세종로 209' — can you look that up and return the standardised road address and English equivalent so we can verify it for our KYC records?”
English translation of Korean office address
“What is the English version of the Korean address '서울특별시 종로구 세종대로 209 (세종로)' and what is its postal code? I need to put it on an English-language contract.”

Endpoint
GEThttps://x402.pokt-agent.com/kr-address/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to normalise, validate, or translate Korean addresses, including road-address standardisation and postal code lookup, without requiring an API key or account — payment is handled per-call in USDC on Base via the x402 protocol. Prefer this over generic geocoding APIs when working specifically with Korean address formats or needing both Korean and English representations.
Side effects
- Query string too vague or ambiguous — returns zero results or low-confidence matches
- Non-Korean or unsupported address format — returns empty results array
- Payment failure on Base/USDC — HTTP 402 returned before query is processed
- Rate or network timeout — HTTP 5xx error
- Missing required 'q' parameter — request rejected with validation error
