Frequently asked questions
Which exchanges do you monitor?
?cex=binance,upbit
query parameter.What types of announcements are detected?
How fast are the alerts?
How fast are you compared to competitors?
Every alternative adds delivery overhead we don’t have: Telegram listing bots typically deliver in 150–500 ms, X / Twitter pipelines in 2–10 s, email alerts in 5–60 s, and DIY scrapers in 200 ms – 2 s. CryptoListing.ws pushes each announcement over a persistent WebSocket the instant it is detected — no broadcast queue, no polling.
That edge comes from a purpose-built low-latency stack and in-region infrastructure: the Tokyo endpoint sits in the same AWS region as Binance, and the Seoul mirror wss://kr.cryptolisting.ws removes the Seoul → Tokyo hop for Upbit — making us consistently the fastest option across all monitored exchanges.
And you don’t have to take our word for it: the free SpeedTrial tier streams the production feed with a 1 ms courtesy delay so paying subscribers are served first and microsecond timestamps on every event, so you can benchmark us directly against whatever you use today.
How do I measure my latency?
Can I use this for automated trading?
How much does it cost?
How do I get an API key?
How do I connect?
wss://cryptolisting.ws or wss://kr.cryptolisting.ws with your API key in the X-API-Key header — the same key works on both. You get structured JSON instantly, with any WebSocket library in any language.Where are your servers located?
Dual-region on AWS. Tokyo (ap-northeast-1a - apne1-az4) hosts the global endpoint wss://cryptolisting.ws — same AWS region as Binance — carrying the full feed. Seoul (ap-northeast-2c - apne2-az3) hosts the Upbit-only mirror wss://kr.cryptolisting.ws.
For the best end-to-end latency, co-locate your bot with the exchange it trades: AWS Tokyo for Binance, AWS Seoul for Upbit.
Which endpoint should I use — Tokyo or Seoul?
Pick by your bot’s location, not the exchange you trade. Bot in AWS Tokyo / Japan → wss://cryptolisting.ws (full feed). Bot in AWS Seoul / Korea → wss://kr.cryptolisting.ws (Upbit only, no Seoul → Tokyo hop).
Same API key on both — one endpoint per bot, chosen by its region.
