Upbit Listing Notice Alert

Detect new Upbit listing announcements the instant they are posted. Capitalize on Korean exchange listing notice pumps with ultra-fast alerts.

Why Upbit listing announcements cause massive price pumps

Upbit is South Korea's largest cryptocurrency exchange, processing billions of dollars in daily trading volume. When Upbit publishes a new coin listing notice, the token's price on international exchanges (Binance, OKX, Bybit) can surge 30-100% within minutes. This is known as the "Upbit listing effect."

The Korean crypto market operates somewhat independently due to regulations, creating the famous "Kimchi premium". New Upbit listings attract massive Korean retail buying pressure, which spills over to global markets. Traders who detect Upbit listing announcements first can position on other exchanges before the pump reaches them.

How to get Upbit listing notice alerts

Connect to our WebSocket. From the Tokyo endpoint, filter for Upbit only with the ?cex=upbit parameter; the Seoul endpoint already streams Upbit announcements exclusively, so the filter is optional there.

# Upbit listings only (Tokyo endpoint)
import json, websocket

def on_message(ws, msg):
    data = json.loads(msg)
    if data["type"] == "announcement":
        print(f"UPBIT LISTING: {data['ticker']}")
        # Execute your trade here

websocket.WebSocketApp(
    "wss://cryptolisting.ws?cex=upbit",
    header=["X-API-Key: YOUR_KEY"],
    on_message=on_message,
).run_forever()

Two endpoints — pick the closest to your bot

We dispatch Upbit listings from two AWS regions. Same API key works on both. Pick by your bot's location, not by what you trade:

• Tokyo — wss://cryptolisting.ws — global feed (Binance, Upbit, Bithumb). Best if your bot lives in AWS Tokyo / Asia-Pacific (Japan). Seoul → Tokyo network hop on the Upbit detection side.
• Seoul — wss://kr.cryptolisting.ws — Upbit-only mirror in AWS Seoul. Best if your bot is co-located in Korea and trades Upbit. Eliminates the Seoul → Tokyo detection hop: ultra-fast end-to-end.

Quick start — Seoul endpoint from a Korea-based bot:

"wss://kr.cryptolisting.ws"

Upbit listing notice detection speed

Our detection engine monitors Upbit's announcement and notice channels continuously, 24 hours a day. When a new listing notice is published, we detect it as soon as their backend updates, parse the ticker and listing details, and broadcast to every connected subscriber. Two endpoints, two latency profiles: from wss://cryptolisting.ws (Tokyo), the announcement crosses a Seoul → Tokyo network hop on the detection side — Upbit's servers are in Seoul. From our Seoul mirror wss://kr.cryptolisting.ws, that hop disappears: a Korea-based trading bot gets ultra-fast end-to-end. The Seoul endpoint dispatches Upbit announcements exclusively — purpose-built for Korea-based Upbit traders.

Either way, we are faster than any other listing alert provider — including other WebSocket services. Our edge comes from purpose-built low-latency infrastructure optimized at every layer. No unnecessary overhead.

Upbit vs Binance listing announcements

Both exchanges cause significant price movements on listing notices, but the dynamics differ. Binance listing announcements tend to have a more gradual impact because Binance is globally accessible. Upbit listing notices create sharper, faster pumps because the Korean market reacts explosively, and international traders need time to catch up. This makes speed even more critical for Upbit announcements.

Multi-exchange monitoring

You don't have to choose. Subscribe to both Upbit and Binance simultaneously:

"wss://cryptolisting.ws?cex=upbit,binance"

Or leave the cex parameter empty to receive listing announcements from all monitored exchanges (Binance, Upbit, Bithumb, and more as they are added). See the full API reference for details.

Frequently asked questions

What kind of Upbit listings does CryptoListing.ws cover?

All new KRW market listings on Upbit, the dominant Korean exchange. Upbit publishes new listings to its announcement page, and our detection engine picks up each new entry within milliseconds. Use ?cex=upbit to subscribe to Upbit only, or combine with bithumb for full Korean market coverage.

Why are Upbit listings important for traders?

Upbit KRW listings consistently produce Kimchi premium events: a new pair often pumps 30-200% in the first minutes because Korean retail demand is large and the local won market is segmented from global liquidity. Bots that act on the listing announcement before the broader market notices can capture significant alpha.

Should I use the Tokyo or Seoul endpoint?

For Upbit specifically, our Seoul endpoint offers the lowest latency since our detection engine and the Upbit infrastructure are both in Korea. The Tokyo endpoint adds a Japan-Korea network hop. If your trading bot is hosted in Korea, use Seoul; if hosted globally, Tokyo is fine for most strategies.

How does latency to Korea affect my fills?

Network round-trip from Tokyo to Seoul is roughly 30 ms. From the US it can exceed 150 ms. For Upbit listing pumps that can move tens of percent in seconds, every saved millisecond matters. The free tier lets you measure real end-to-end timing from your own infrastructure.

Can I subscribe to Upbit and Binance together?

Yes. Use ?cex=upbit,binance on a single connection to receive announcements from both exchanges through one WebSocket stream. The listingExchange field on each message tells you which exchange it came from, so your bot can route orders to the correct venue.
