Listing detection and WebSocket performance
New Listings Feed turns exchange announcements into structured listing and delisting alerts for trading systems.
WebSocket speed and uptime
New Listings Feed provides low-latency detection across supported exchanges. Our WebSocket service has maintained 99.9% uptime over 18+ months.
Our historical event records document the announcements we have processed. Each v2 event includes detection and send timestamps, so you can measure delivery at your own client.
From exchange notice to listing alert
We detect exchange announcements and extract the exchange, event type and tickers. The feed covers spot listings, futures, delistings and exchange-specific events such as Binance Alpha and Upbit KRW additions.
Token and market data
Parsed events include tickers and the original announcement. Paid keys also include token contracts, market metrics and DEX data when available. Suggested token matches are identified separately from confirmed contracts.
Measuring delivery speed
Each event records when we detected the announcement and when we sent it. Comparing those times with arrival at your client shows the delivery time for your setup.
The historical listings on our exchange pages show previous events, with examples of how their data appears in v2 JSON.
