## 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-why-moving-stock-intelligence-api-6fe9609d
```

## When to prefer this

Choose this endpoint when you need a narrative, knowledge-graph-backed explanation of *why* a specific Korean stock moved — not just raw price data. It is ideal when the user wants news sentiment, event attribution, and move-specific context for a KRX-listed company, and when you need that signal in a single structured call without managing a subscription or API key.

## Known failure modes

- Invalid or unrecognized KRX ticker returns empty or error response
- No big move events if the stock has been flat during the period
- Payment failure in USDC on Base Mainnet blocks request
- Ticker format mismatch (e.g. wrong zero-padding) may yield no results
- Data may lag if knowledge graph has not yet processed very recent news

## 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

Returns a JSON object with the stock's seed info (ticker code and name in Korean), an as-of date, a list of big move events each with date, related news titles and sentiment scores, closing price and daily return, and an overall period return — all sourced from DeepSearch's knowledge graph for Korean listed companies.
