“Can you pull the 3-year daily price history for Kakao (KRX ticker 035720) and Naver (KRX ticker 035420) so I can compare how their stock performance and market caps have trended against each other over time?”

Technical details
Endpoint
GEThttps://x402.deepsearch.com/v1/context/stock/:ticker/3yWhen to prefer
Use this endpoint when you need the longest available daily price history (up to 3 years, ~780 points) for a KRX-listed or supported US stock — ideal for long-term trend analysis, backtesting strategies, or computing multi-year technical indicators. Prefer the 1-month or 1-year endpoints if you only need shorter windows and want to minimize cost.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty dataset
- Unsupported exchange code results in a default KRX lookup or error
- Stock with limited trading history returns fewer than 780 data points
- Payment failure (insufficient USDC) blocks the request with a 402 response
- Rate limiting or network timeout returns a 429 or 5xx error
