## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability korean-address-normalisation-search-b6d0b01a
```

Example prompt: Can you look up and normalise this Korean address for me — '서울특별시 종로구 세종대로 209' — and give me the official road address, English translation, and postal code?

## When to prefer this

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.

## Known failure modes

- 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

## 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).
