## 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-name-romanization-api-a1beedf8
```

Example prompt: Can you romanize the Korean name 이철수 and give me all the common English spelling variants, including McCune-Reischauer, Revised Romanization, and any other ways it might be written?

## When to prefer this

Choose this endpoint when you need all standard romanization systems (McCune-Reischauer, Revised Romanization, Yale) plus common variant spellings for a Korean name in a single call — especially for compliance, KYC, sanctions screening, or document matching workflows where name spelling inconsistencies across passports and official records matter. It requires no API key and charges $0.005 USDC per call via x402 on Base, making it ideal for pay-as-you-go agent pipelines.

## Known failure modes

- Missing required 'name' query parameter returns a 400 error
- Non-Korean input (e.g. already-Latin text) may return unexpected or empty results
- Payment not included or insufficient USDC on Base returns a 402 Payment Required response
- Invalid 'kind' enum value (not 'person' or 'company') may return a 400 error
- Very rare or archaic Hanja characters may not be recognized

## 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 three romanization system outputs (McCune-Reischauer 'mr', Revised Romanization 'rr', Yale 'yale') plus an array of common real-world spelling variants used in passports, legal documents, and international contexts.
