Example prompt: Can you pull the last 3 months of daily closing prices for Samsung Electronics (KRX ticker 005930) from DeepSearch — I want to see the date, close price, daily change percent, and market cap for each day?

## When to prefer this

Choose this endpoint when you need recent short-term (3-month) daily price history including market cap and daily change percentage for KRX-listed Korean stocks or supported US symbols. It is cost-effective at $0.05 USDC per call and ideal for trend analysis, short-term momentum checks, or building charts covering the past quarter. Use sibling endpoints for longer historical windows (up to 3 years) or fundamental financial data.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty dataset
- Unsupported exchange code causes a bad request response
- Ticker provided in wrong format (e.g. 5 digits instead of 6 for KRX) may return no data
- Payment failure via x402 protocol blocks the request
- Rate limiting or upstream data unavailability may cause timeouts
