## 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 deepsearch-korean-stock-intelligence-api-88110f1d
```

Example prompt: Pull up the financials and current price for Samsung Electronics (ticker 005930) on the KRX — I need PER, PBR, ROE, and market cap.

## When to prefer this

Use this endpoint when you need comprehensive Korean stock market data — financials and price history — for any of the 2,000+ KRX-listed companies, especially when you want pay-per-query access without a subscription commitment. Prefer this over general market data APIs when the focus is specifically on Korean equities with deep historical financial context.

## Known failure modes

- Invalid or unknown ticker code returns an error or empty result
- Payment not fulfilled results in HTTP 402 response blocking access
- Exchange code not supported returns an error
- Network timeout for slow upstream data fetch
- Ticker for a delisted company may return incomplete or no data

## How this service works

Up to 10 years of financials + 3 years of daily price history for all 2,000+ KRX stocks. Pay-per-query with USDC on Base Mainnet — no subscription.

## Output

A JSON object containing the company name, ticker, current price, market cap, and key valuation ratios (PER, PBR, ROE) sourced from up to 10 years of financial data and 3 years of daily price history for the requested KRX-listed stock.
