CryptoListing.ws vs other WebSocket listing providers
Plenty of services stream crypto data over WebSocket. CryptoListing.ws does one job, for trading bots: it pushes listing, delisting and other exchange announcements from Binance, Upbit, Bithumb and Robinhood to your bot as clean JSON, in real time. Here is what you get, and what to check before you choose any provider.
What your bot gets with CryptoListing.ws
All of it is live today and documented in the API documentation.
Real-time WebSocket push
Keep one WebSocket open: each announcement is pushed to your bot as soon as it is detected. No request loop, no page to scrape.
Ticker already extracted
Clean JSON with ticker, publisher and listingType on every event, next to the original exchange title. Upbit listings also name the markets that open (KRW, BTC, USDT).
Listings, delistings and more
Spot and futures listings, spot and futures delistings, Binance Monitoring Tag changes, HODLer airdrops, Upbit and Bithumb caution releases, and Robinhood Listing and Robinhood Live events.
Microsecond timestamps
Detection and dispatch times in microseconds on every event, so you can measure delivery to your own servers.
Three endpoints, one API key
Tokyo, Seoul and US. The same key works on all three, and ?cex= filters any of them by exchange.
Two free tiers
SpeedTrial runs on the same dispatch path as Premium, with a 1 ms courtesy delay and the ticker and title redacted, so you can benchmark us: a free 15-day key, renewable on request. FreeDelayed is the full feed with a 240 ms delay, free for the first month, then a monthly fee for all exchanges.
Public price charts
Every Binance, Upbit and Bithumb announcement gets a public page with its detection time and, when the token already traded, a price chart you can zoom down to the millisecond.
Docs and code examples
Quick start, message reference, AsyncAPI schema and working examples in Python, Node.js, Go and Rust.

Tokyo, Seoul, US: pick the endpoint closest to your bot
- Tokyo,
wss://jp.cryptolisting.ws. The full feed for Binance, Upbit and Bithumb. Binance is served from Tokyo only. - Seoul,
wss://kr.cryptolisting.ws. Upbit and Bithumb, ultra-fast end-to-end for bots co-located in Korea. - US,
wss://us.cryptolisting.ws. Robinhood: Robinhood Listing (not tradable yet on Robinhood) and Robinhood Live (tradable on Robinhood). - One API key on all three. Connect to several at once and filter each one with
?cex=to avoid duplicates.
Every announcement, public and checkable
You don’t have to take our word for it. Latest listings shows the Binance, Upbit, Bithumb and Robinhood announcements we detect, each on its own page — with a price chart for Binance, Upbit and Bithumb. The listing price reaction statistics show how prices moved after each type of announcement since April 2026. The same announcements are free as a JSON feed and an Atom feed for RSS readers, with no key.

Frequently asked questions
What does a CryptoListing.ws message look like?
One JSON object per announcement: the original exchange title, the ticker (comma-separated when one announcement names several tokens), the publisher, the listing type, and the detection and dispatch timestamps in microseconds. Upbit spot listings also carry a markets field. The message reference in the documentation lists every field.
Does CryptoListing.ws have a Seoul endpoint?
Yes. wss://kr.cryptolisting.ws runs in AWS Seoul and carries Upbit and Bithumb, for bots co-located in Korea. The same API key works on the Tokyo, Seoul and US endpoints; rate limits and connection caps are tracked per server.
Can I use several endpoints at once?
Yes. For example, open wss://jp.cryptolisting.ws filtered with ?cex=binance, wss://kr.cryptolisting.ws for Upbit and Bithumb, and wss://us.cryptolisting.ws if you trade Robinhood. Same API key on all three; connection caps apply per server.
How can I check the timing myself?
Every event carries detectedTimestampUs and dispatchTimestampUs, in microseconds. Compare them with your own receive time to measure delivery to your servers on real announcements. The free SpeedTrial key uses the same dispatch path as Premium, with a 1 ms courtesy delay so that paying subscribers are served first.

Yes. Ask for a free SpeedTrial or FreeDelayed key on Telegram: SpeedTrial is a 15-day key, renewable on request; FreeDelayed is free for the first month, then a monthly fee for all exchanges. Basic and Premium are billed per exchange; see the pricing page.
