## 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-full-financials-price-history-0b2ff57f
```

Example prompt: Can you pull the full financial history and daily price data for Samsung Electronics (ticker 005930) on the KRX from DeepSearch? I want to see up to 10 years of financials and 3 years of price history.

## When to prefer this

Use this endpoint when you need comprehensive fundamental financial data (income statement, balance sheet, revenue trends) and/or daily price history specifically for KRX-listed Korean stocks. Prefer this over general financial APIs when Korean market coverage and up to 10-year depth are required, and when a pay-per-query model without subscription overhead is preferred.

## Known failure modes

- Invalid or unknown KRX ticker returns an error or empty result
- Insufficient USDC balance on Base Mainnet causes payment failure (402 response)
- Non-KRX exchange tickers not supported — US or other exchange tickers will fail
- Network or upstream data unavailability causes 5xx errors
- Missing required ticker query parameter returns 400 validation error

## 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 ticker symbol and an array of financial periods with metrics such as revenue (in Korean won units), fiscal end dates, and related financial statement data, along with daily price history covering up to 3 years.
