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
A JSON object containing: the stock's ticker and name, the as-of date, a net buy breakdown (1-day window) split into foreigner, individual, and institutional flows in KRW (positive = net buy, negative = net sell), an array of block trade records (date, volume, closing price in KRW, change percent, share of total volume), and an array of short selling records (date, volume, amount in KRW, share of total volume).
Example use cases
Foreigner flow surveillance on KOSPI
“Show me the foreigner net buy and sell figures for Kakao (ticker 035720) on KRX today — I want to know if overseas investors are accumulating or dumping shares.”
Short selling pressure check before earnings
“Before SK Hynix reports earnings, can you pull the short selling volume and its share of total trading volume for ticker 000660 on the KRX?”
Block trade detection for institutional activity
“Are there any notable block trades in LG Energy Solution (ticker 373220) recently? I want to see dates, volumes, and how they compare to total daily trading volume.”
Technical details
Endpoint
GEThttps://x402.deepsearch.com/v1/context/flows/%7Bticker%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need granular investor-type flow data (foreigner vs. retail vs. institutional net buy/sell) for a specific KRX-listed Korean stock, especially to detect unusual accumulation, distribution, block trades, or short-selling pressure. Prefer this over the full company report endpoint when you only need flow/sentiment signals and want to minimize cost ($0.05 vs $0.30+). Not suitable for US stock flows or crypto assets.
Side effects
- Invalid or unrecognized KRX ticker returns an error or empty response
- Payment failure (insufficient USDC balance on Base Mainnet) results in 402 response
- Data not yet available for the current trading day (market still open or settlement delay)
- Non-KRX tickers (e.g. NYSE, NASDAQ) are not supported by this endpoint
- Network timeout or upstream data feed outage
