A DataMaxi+ alternative focused on listing announcements

DataMaxi+ is a crypto data platform for traders, with listing data among its datasets. CryptoListing.ws is built around a single event: the exchange announcement. If your bot needs Binance, Upbit, Bithumb and Robinhood announcements as real-time, machine-readable events, here is what you get.

One event, pushed the moment it is detected

When Binance, Upbit or Bithumb posts a listing, delisting or caution notice, or a token is added to Robinhood (Robinhood Listing) or becomes tradable there (Robinhood Live), CryptoListing.ws pushes it to every connected bot as a single JSON message over a WebSocket: the original title, the ticker already extracted, the publisher, a listingType to route on, and detection and dispatch times in microseconds. Nothing to poll, no title to parse — your code receives an event it can act on.

• Classified events. Spot and futures listings, delistings, Monitoring Tag changes, HODLer airdrops, caution releases and Robinhood’s two event types each have their own listingType.
• Microsecond timestamps. detectedTimestampUs and dispatchTimestampUs on every message, so you can measure delivery on your own host.
• Three regional endpoints, one key. Tokyo, Seoul and N. Virginia; ?cex= keeps only the exchanges you trade.

Upbit and Bithumb, covered in depth

• New listings with their markets. Upbit KRW listings and Bithumb listings arrive as spot_listing; each Upbit listing carries a markets field (KRW, BTC, USDT), so a new KRW market is told apart from a BTC-only pair without reading the Korean title.
• The caution lifecycle. A lifted designation (유의 종목 지정 해제) arrives as caution_released and the end of trading support (거래지원 종료) as spot_delisting — the two stages traders act on. See caution released.
• A Seoul endpoint. wss://kr.cryptolisting.ws, in AWS Seoul, carries Upbit and Bithumb for bots running in Korea.

Binance and Robinhood on the same key

From the Tokyo endpoint, wss://jp.cryptolisting.ws: Binance spot and futures listings, delistings, HODLer airdrops, and tokens added to or removed from the Monitoring Tag. From N. Virginia, wss://us.cryptolisting.ws: Robinhood — wallet_listing (Robinhood Listing) when a token is added to Robinhood but not tradable yet on Robinhood, and cex_listing (Robinhood Live) when it becomes tradable on Robinhood.

Free keys to wire your bot

Two free tiers let you build before you pay. SpeedTrial, made for benchmarking, is served by the same dispatch pipeline as Premium, with the ticker and title redacted and a 1 ms courtesy delay so paying subscribers come first. FreeDelayed carries the full feed with a 240 ms delay — enough to build and test your logic on real announcements. SpeedTrial is a free 15-day key, renewable on request; FreeDelayed is free for the first month, then a monthly fee for all exchanges. Both are usually issued on Telegram within minutes.

Send {"type":"test"} at any time to receive a test announcement (one per minute per key). The documentation covers the quick start, every message field, an AsyncAPI schema and working clients in Python, Node.js, Go and Rust.

Past announcements, on the record

Each announcement on latest listings is kept on a public page: its detection time to the microsecond and, if the token was already trading, a trade-by-trade chart of the price from the first milliseconds up to 24 hours later. The listing price reaction statistics give the median move per exchange and announcement type, and the caution release record lists the Upbit and Bithumb releases tracked since April 2026. The same data is free as a JSON file and an Atom feed, with no key.

Fits next to your market data

CryptoListing.ws does one job. If your strategy also reads prices, premiums or spreads, keep that source: the announcement feed fires the trigger, and your market data gives the context around it.

FAQ

Is CryptoListing.ws a good DataMaxi+ alternative?

Yes, if the listing announcement is your trigger. CryptoListing.ws pushes every Binance, Upbit, Bithumb and Robinhood listing, delisting and caution release as structured JSON over a WebSocket, with the ticker extracted, microsecond timestamps and free keys to test it. It focuses on announcements only, so it sits well next to the market data you already use.

Can I use the WebSocket API for free?

Yes. SpeedTrial (ticker and title redacted, 1 ms courtesy delay, for benchmarking) is a free 15-day key, renewable on request; FreeDelayed (full feed, 240 ms delay) is free for the first month, then a monthly fee for all exchanges. Both are issued on Telegram. Paid tiers are on the pricing page.

Which Upbit and Bithumb events does it send?

New listings (with the markets field on Upbit), caution releases (caution_released) and delistings (spot_delisting). Both exchanges are also served from the Seoul endpoint, wss://kr.cryptolisting.ws.

Does CryptoListing.ws cover Robinhood?

Yes. Robinhood has two event types — wallet_listing (Robinhood Listing) when a token is added to Robinhood but not tradable yet on Robinhood, and cex_listing (Robinhood Live) when it becomes tradable on Robinhood — from the US endpoint, wss://us.cryptolisting.ws, on the same API key.
