## 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-issue-context-endpoint-8729c0aa
```

Example prompt: Pull the latest news issues and sentiment for Samsung Electronics (ticker 005930) on the KRX exchange using DeepSearch — I want to see what stories are relevant and whether the sentiment is positive or negative.

## When to prefer this

Use this endpoint when you need structured news issue intelligence — including sentiment and relevance scoring — for a specific KRX-listed Korean stock. It is especially useful for agents doing investment research, portfolio monitoring, or financial analysis on Korean equities (KOSPI/KOSDAQ). Prefer this over generic news search when you need machine-readable sentiment and relevance scores tied directly to a stock ticker, and when pay-per-query pricing (no subscription) is preferred.

## Known failure modes

- Invalid or unknown ticker returns empty issues array or 404 error
- Missing required ticker query parameter returns 400 bad request
- Payment failure (insufficient USDC balance on Base Mainnet) returns 402 Payment Required
- Unsupported exchange code may default to KRX or return an error
- Rate limiting or network timeout if DeepSearch backend is overloaded

## 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

Returns a JSON object containing the ticker and a list of issues, each with a title, a relevance score (0–1 float), and a sentiment label (positive/negative/neutral). Useful for understanding what news stories are currently impacting a specific Korean stock.
