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

Example prompt: Can you fact-check the numbers in this Korean earnings report for Samsung Electronics for fiscal year 2023? Here's the text: '영업이익은 6조 5천억원이며, 한국은행 기준금리는 3.5%p입니다.' — please verify each figure against the official DART and BoK records as of 2023-12-31.

## When to prefer this

Choose this endpoint when you need to validate specific numerical claims in Korean-language financial or economic documents against authoritative Korean official sources (BoK ECOS for rates, KEXIM for exchange rates, DART for listed-company financials). It is purpose-built for Korean finance fact-checking with native unit handling (조/억/만) and % vs %p disambiguation, making it far more precise than generic fact-checking or OCR tools for this domain.

## Known failure modes

- Text exceeds 20,000 character limit — request will be rejected
- No checkable figures found in text — returns empty result set
- Company name not recognized in DART — figures returned as unverified
- As-of date outside available data range — source lookup fails
- Ambiguous unit notation (조/억/만) leads to misinterpretation
- Rate or yield not available for specified date — marked unverified

## How this service works

Do the numbers in a Korean finance text match the official record? Send Korean text; get each checkable number marked MATCH or MISMATCH with the official value, date and source: % vs %p, 조/억/만 units, BoK base rate and KTB yields (ECOS), KRW exchange rates (KEXIM), listed-company revenue and profit (DART). Numbers with no source stay unverified. POST /v1/check.

## Output

A structured response listing each checkable number found in the input Korean text, with a MATCH or MISMATCH verdict, the official value from the authoritative source (BoK ECOS, KEXIM, or DART), the source name, and the reference date. Numbers that cannot be matched to any official source are flagged as unverified.
