Technical details
Endpoint
GEThttps://x402.deepsearch.com/v1/context/stock/%7Bticker%7D/1yWhen to prefer
Choose this endpoint when you need structured daily closing price history for Korean (KRX) stocks specifically, especially when you want pay-per-query access without a subscription. Ideal for agents performing ad-hoc equity research, backtesting signals, or charting Korean equities. Prefer this over broader financial data providers when the focus is KRX-listed stocks and cost-per-call transparency is important.
Side effects
