## 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-corporate-financial-statements-api-531f6f29
```

Example prompt: Can you pull Samsung Electronics' consolidated annual income statement and balance sheet for fiscal year 2022? Their Korean ticker is 005930.

## When to prefer this

Use this endpoint when you need structured financial statement data for Korean publicly listed companies, especially when you have a 6-digit Korean stock ticker or 8-digit DART corp code. Prefer this over general financial data APIs when the target is a Korean company filing with DART (Korea FSS). It supports historical data from 2015 onward with granularity down to quarterly (q1, q3) and half-year periods.

## Known failure modes

- Invalid or unrecognized ticker/corp_code returns empty result or error
- Year before 2015 not supported (minimum year constraint)
- Company not publicly listed on Korean exchanges returns no data
- Ambiguous company name with no ticker/corp_code may return wrong entity
- Consolidated statements unavailable for some companies — fallback to separate basis needed
- DART data lag may mean recent quarters are not yet available

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with success flag and a result object containing the requested financial statements (income statement, balance sheet, and/or cash flow) for the specified Korean company and fiscal year, structured as standardized financial line items.
