The Bit-Z Websocket Market Data API allows developers to subscribe and unsubscribe from data streams. For a given trading pair, streams are available that provide the market overview, depth, contract note, and K-line. This API will only return GZIP compressed data, which should be decompressed locally.
Bit-Z is a popular digital assets trading exchange with branches in multiple countries and regions, including Singapore, Japan, and South Korea. Documentation is provided in Chinese, Japanese, Korean, and English.
