## 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`):

Example prompt: Why has Samsung Electronics (KRX: 005930) been moving so much lately? Show me the biggest daily price swings over the last 45 trading days with any news headlines or filings that might explain them.

## When to prefer this

Use this endpoint when you need to quickly contextualize recent price volatility for a KRX-listed stock with Korean news and filings — especially useful for research, due diligence, or explaining anomalous moves to clients. Prefer over generic news search when you want pre-correlated, sentiment-tagged Korean financial news aligned to specific price move dates. Best for the ~45-day recent window; use the financial history or fundamentals endpoints for longer-term analysis.

## Known failure modes

- Invalid or non-KRX ticker returns an error or empty result
- Ticker exists but has no significant price moves in the window (flat stock)
- News knowledge graph may have sparse coverage for small-cap or illiquid stocks
- Filings database may lag real-time disclosures
- Response caveats that correlation ≠ causation where evidence is thin

## How this service works

For a KRX stock, the largest daily price moves of the last ~45 trading days, each paired with that day's representative news headlines (with sentiment) and filings within ±2 days, plus the period return. Built from DeepSearch's Korean news knowledge graph. Correlation, not causation — the response says so where evidence is thin.

## Output

A structured response listing the largest daily price moves (up and down) for the given KRX ticker over the last ~45 trading days, each annotated with representative Korean news headlines including sentiment scores, and any regulatory or IR filings published within ±2 days of that move. Also includes the overall period return. The response explicitly notes where correlations are thin and causation cannot be inferred.
