Financial Data Api For Korean Stocks?

hi everyone, im building a python screener / trade tracker for my portfolio. currently im using xfinlink for US data with eodhd and yfinance as fallback but i need high quality korean fundamentals data, which none of them seem to provide (xfinlink is US-only; eodhd and yfinance yes but inaccurate in many instances).

anyone running python/screener pipelines on korean securities and can share a reputable & reliable data vendor? cost is not really a concern for me. quality is. FYI I’ll be buying as retail so would appreciate recommendations that offer non-institutional plans. cheers.
