## 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-2-year-financials-041d1455
```

Example prompt: Can you pull the last 2 years of financials for Samsung Electronics on the KRX — I want to see revenue and operating profit by quarter? The ticker is 005930.

## When to prefer this

Use this endpoint when you need fundamental financial data (revenue, operating profit) for any of the 2,000+ stocks listed on the Korea Exchange (KRX), covering a 2-year historical window. Prefer this over broader data providers when you specifically need Korean market data paid per-query with no subscription overhead, and when you need recent financial period data in a structured JSON format.

## Known failure modes

- Invalid or unknown KRX ticker returns an error or empty periods array
- Payment failure (insufficient USDC balance) returns HTTP 402
- Ticker not listed on KRX returns a not-found error
- Malformed query parameters return a 400 validation error
- Network timeout or upstream data unavailability returns a 503

## 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, each with fiscal end date, revenue (in Korean won notation), and operating profit. Covers up to 2 years of historical quarterly/annual data for the requested KRX stock.
