## 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-korea-us-stock-intelligence-api-briefing-4a314d0a
```

Example prompt: Give me today's AI briefing for Samsung Electronics (KRX: 005930) — I want to know why the stock moved, what analysts think, and which themes are driving it right now.

## When to prefer this

Choose this endpoint when you need a rich, AI-synthesized stock intelligence briefing specifically for Korean KRX or US equities — especially when you want not just raw price data but explanatory context (why a stock moved, what themes are hot, analyst consensus, investor flows, and knowledge-graph signals). Prefer this over generic financial data APIs when the user needs actionable narrative intelligence rather than raw tick data, and when pay-per-call USDC pricing on Base Mainnet is acceptable.

## Known failure modes

- Invalid or unsupported ticker returns an error or empty result
- Payment failure on Base Mainnet (insufficient USDC balance) blocks the request
- Intraday briefing may not yet be available before market open
- Non-KRX / non-US tickers are not supported
- Network or provider downtime results in 5xx errors
- Malformed ticker format (e.g. missing leading zeros for KRX codes) may return no data

## How this service works

Korean (KRX) stock data for AI agents: analyst consensus, investor flows, market pulse, knowledge-graph signals (why a stock moved, hot themes, theme revenue evidence), 10-year financials and 3-year prices, plus US fundamentals and SEC filings. Pay per call in USDC on Base Mainnet — no subscription, no API key.

## Output

A JSON object containing the date, company name, ticker, current price in KRW, percentage change, a language-tagged AI-generated briefing text, a short headline, pack type, and an array of source articles (URL, title, publisher, publishedAt) that informed the briefing. Optionally includes analyst consensus, investor flow data, knowledge-graph theme signals, 10-year financials, and 3-year price history depending on pack type.
