aikstockdata
Free Korean stock market data API: T+1 closing prices for KOSPI/KOSDAQ/KONEX stocks, DART filings, and accumulating daily price history as JSON and CSV, with no API key or signup.
Publishes daily closing prices for 2,778 KOSPI/KOSDAQ/KONEX stocks, KOSPI and KOSDAQ index levels, DART regulatory filings with materiality scores, earnings data, and per-stock accumulating price history. Data is sourced from the FSC open data portal and DART, updated every trading day around 18:30 KST, and served as self-describing JSON, CSV, JSON Schema, and an OpenAPI 3.1 spec. Also provides an MCP server (12 tools, Streamable HTTP, no auth) for querying the data from AI assistants, plus datasets on Hugging Face and Kaggle. Prices are T+1 settled closes, not real-time. Terms: non-commercial use with attribution; commercial redistribution not permitted.
