Introduction
Real-time WebSocket feed for crypto exchange listing announcements. Connect over WSS, receive structured JSON the moment a listing, delisting, or risk event is detected.
No key yet? Binance, Upbit and Bithumb listings, delistings and risk events, and Robinhood events, are also published as a free JSON file and Atom feeds, readable without an API key — see Public JSON & Atom Feeds.
For LLMs, full documentation in a single txt file here.
