How this service works
Up to 10 years of financials + 3 years of daily price history for all 2,000+ KRX stocks. Pay-per-query with USDC on Base Mainnet — no subscription.
Output
A JSON object containing the ticker symbol, the period ('1m'), a count of data points (typically ~22 trading days), and an array of daily data points each with date, close price, and percent change from the prior day.
Example use cases
Monitor competitor stock momentum in Korean market
“Pull the last month of daily closing prices for our three main competitors on the KRX - could you grab those for me and tell me which one has been gaining the most traction lately?”
Track Korean tech stock performance trends
“I need to keep tabs on how Naver and Kakao have been moving over the past month. Can you fetch their daily closing prices from DeepSearch so I can spot any interesting patterns?”
Analyze recent volatility for investment decisions
“Before I make a decision on adding Korean stocks to our portfolio, can you pull the daily price history from the last month for Samsung, SK Hynix, and LG Electronics so I can see which one has been most stable?”
Technical details
Endpoint
GEThttps://x402.deepsearch.com/v1/context/stock/%7Bticker%7D/1mWhen to prefer
Use this endpoint when you need recent (1-month) daily price history for KRX-listed stocks or US symbols, especially when you want pay-per-query pricing with no subscription commitment. Prefer this over broader financial data APIs when you specifically need Korean market (KRX) coverage across 2,000+ stocks.
Side effects
- Invalid or unknown ticker returns an empty data set or error response
- Non-KRX tickers without specifying exchange may return unexpected results
- Payment failure (insufficient USDC balance) returns HTTP 402 and no data
- Network timeout if the KRX data backend is slow
- Ticker with insufficient trading history may return fewer data points than expected
