LINE Yahoo Data Parser & API

LINE Yahoo (LY Corporation) operates Yahoo! Finance Japan, the leading retail finance and market-data portal for Japanese investors, and StockAPIS extracts its data — JP stock quotes, Nikkei 225 and TOPIX index levels, FX rates, fund NAVs and finance headlines — through a single REST API. LINE Yahoo does not publish a public market-data API, so StockAPIS parses the portal directly and normalizes the output to the same schema you use for every other source, letting you query Japanese retail market data alongside global brokers without a separate integration.
