HKEX (Hong Kong Exchanges and Clearing Limited, SEHK 388) operates the Stock Exchange of Hong Kong, the Hong Kong Futures Exchange, and their clearing houses, and also owns the London Metal Exchange. As an exchange data arm it sells real-time securities and derivatives market data through the sales-gated HKEX Orion Market Data (OMD) platform - binary multicast datafeeds licensed to vendors and subscribers rather than a self-serve HTTP API - plus historical tick, full order book, and CCASS shareholding reference data through the HKEX Data Marketplace, delivered via SFTP, cloud-to-cloud transfer, and direct download. Its one publicly documented RESTful JSON API is the FINI API Gateway for IPO settlement workflows, restricted to registered market participants using OAuth 2.0 JWT credentials.
