Frequently asked questions
Which exchanges do you monitor?
?cex=binance,upbit
query parameter.What types of announcements are detected?
wallet_listing) and Robinhood Live (cex_listing) events, plus maintenance and token-swap announcements. Every message carries the type, so you can filter programmatically.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 and Bithumb — 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.

wss://jp.cryptolisting.ws, wss://kr.cryptolisting.ws or wss://us.cryptolisting.ws (Robinhood) with your API key in the X-API-Key header — the same key works on all three. You get structured JSON instantly, with any WebSocket library in any language.Where are your servers located?
Three regions on AWS. Tokyo (ap-northeast-1a - apne1-az4) hosts the global endpoint wss://jp.cryptolisting.ws — same AWS region as Binance — carrying the full feed. Seoul (ap-northeast-2c - apne2-az3) hosts the Korea-region mirror wss://kr.cryptolisting.ws, carrying Upbit and Bithumb. A third endpoint, wss://us.cryptolisting.ws in AWS N. Virginia (us-east-1a - use1-az1), carries Robinhood only.
For the best end-to-end latency, co-locate your bot with the exchange it trades: AWS Tokyo for Binance, AWS Seoul for Upbit and Bithumb, AWS N. Virginia for Robinhood.
Which endpoint should I use — Tokyo, Seoul or N. Virginia?
Pick by your bot’s location, not the exchange you trade. Bot in AWS Tokyo / Japan → wss://jp.cryptolisting.ws (full feed). Bot in AWS Seoul / Korea → wss://kr.cryptolisting.ws (Upbit + Bithumb, no Seoul → Tokyo hop). Bot trading Robinhood → wss://us.cryptolisting.ws (Robinhood only, AWS N. Virginia).
Same API key on all three — one endpoint per bot, chosen by its region.
