The fastest listing feed for crypto sniper bots

Build your crypto sniper bot on the New Listings Feed ultra-low-latency WebSocket API, built for speed and performance. Receive raw announcements before parsing, or parsed events ready for your bot to process. This guide explains how to choose between them and compare delivery times from the server where your bot runs.

Receive listing announcements directly in your application

With interval-based polling, your bot asks whether anything changed and may wait for its next request to discover an update. A WebSocket connection stays open so the server can send each message when it is ready. Your application receives events without adding its own polling interval.

Telegram and X are useful for following announcements. A direct WebSocket gives your software structured events without a chat-reading step. The New Listings Feed WebSocket also powers our public channels, so bots can consume the underlying streams directly.

WebSocket is the delivery protocol. Detection speed, configured delay and the route to your server still affect arrival time. That is why choosing the fastest listing feed needs an actual comparison on the setup you plan to use.

Choose raw announcements or parsed listing events

Choose the feed by the work your bot can do when a message arrives. A client with its own parser can use a raw notice immediately. For bots that want classified markets, tickers or contract addresses, measure when those fields become available.

New Listings Feed offers both choices. The raw stream sends before parsing; the full stream supplies the parsed event and optional onchain enrichment. Comparing a raw arrival against a complete parsed event would compare different products.

STARTER and PRO include both v2 streams in Tokyo, New York and Seoul. For Seoul, connect to wss://seoul.newlistings.pro/v2/fast for raw announcements or wss://seoul.newlistings.pro/v2/full for parsed events. FREE uses wss://ws.newlistings.pro/v2/full. Our regional guidance is New York for Coinbase and Robinhood, and Tokyo for the other covered exchanges. Compare arrivals from your own server when choosing a paid region.

Filter the exchange, market and event

A fast message is useful only if it describes an event your system follows. A Binance perps listing, a spot listing and an Alpha notice are different events. On Upbit, a new USDT pair is different from a KRW market addition. Bithumb listing and trading-support termination notices also need separate handling. For Robinhood, keep asset-catalog discoveries separate from spot listing notices.

The published Upbit examples below show why this matters. BFC has markets: ["krw"] and passes a KRW listing filter. REZ has markets: ["usdt"] and is skipped by that same filter. Both are spot listings; checking only the exchange and spot type would accept both.

Why onchain bots need more than a ticker

A ticker names the announced symbol. A chain and contract address identify the onchain asset your system can look up. New Listings Feed full events keep exchange-published contracts separate from inferred suggested_match candidates, with confidence labels on those candidates.

When available, DEX pools, liquidity and market metrics add context for your own checks. If a contract address is required for your bot, compare the arrival of the event carrying that address. Timing a raw headline alone leaves out the work your system still needs to do.

Why detection time, delivery and execution are different

An announcement is published, the feed detects it, and a message is sent to your application. Your bot then parses or evaluates the event and decides what to do. Each step answers a different timing question.

New Listings Feed events carry detection and publication timestamps. Our historical records show detection usually within 1–20ms of original announcement publication for many exchanges. The delivery guide measures from Full event publication to your client, after the configured plan delay. Fast records its publication timestamp before that delay.

Listing sniping also involves your own market-data and execution connections. Receiving an announcement does not mean an exchange has opened trading or an order has filled. New Listings Feed supplies event data; you build and run the execution system.

Why a public track record matters for your listing bot

Your bot can put real money at risk. Signal provenance matters. You should be able to trace an alert to the original exchange notice, assess who runs the feed and see how errors are handled.

An unvetted vendor with no public track record or established reputation adds risk. You have less evidence to judge its data quality, reliability and accountability when something goes wrong. Fast delivery alone does not answer those questions.

New Listings Feed has been built in the open for over two years. Thousands of traders read our public feeds day to day. The main Telegram channel has 50k+ subscribers, and our Telegram and X channels publish from the same streams available through the WebSocket API.

Our public archive contains timestamped announcements with original exchange links, and we investigate reported mistakes. Inspect that operating history alongside the detection records and your own delivery tests before using a feed in live trading.

Compare the arrivals your listing bot uses

New Listings Feed is the fastest listing feed for bots and sniping. Test the same announcements with the information your application uses, using the setup below. The speed guide explains raw-versus-parsed comparisons, configured delays and what to record in a complete sample.

  1. Use the server where your bot will run

    Record the receiver location, client version, provider endpoint and subscription plan. Keep the receiving host and workload consistent across captures.

  2. Match the announcement and payload type

    Use the official notice URL, exchange and event type to match events. Compare raw notices with raw notices, or parsed events with parsed events. Include any enrichment your bot requires.

  3. Capture arrival before other client work

    For two feeds on one receiver, use the same monotonic clock to record arrivals before parsing or logging. For publication-to-client measurements, check clock synchronization and keep the original timestamp rows.

  4. Compare a complete sample

    Collect events across multiple sessions. Report the sample size, filters, missing events and disconnects alongside typical arrival differences and the largest gaps. Keep the source logs so another run can be compared with the first.

Connect your listing bot to the WebSocket API

Start with a FREE key at wss://ws.newlistings.pro/v2/full to inspect parsed events and test your integration. FREE has a 3-second configured delay and no onchain enrichment. Its publication-to-client measurement starts after that delay, so a small result does not demonstrate PRO speed.

Choose one exchange and market type for your first test. Read the READY message for the plan and delay applied to your key, then check that your client accepts the intended event classification and tickers.

For our fastest delivery for listing bots and sniping, test PRO with zero configured delay on the endpoint your bot will consume. Network delivery and client processing still take time. STARTER and PRO include both v2 streams and the same optional onchain fields.

New Listings Feed covers 24 parsed exchange feeds, with listing, launch and additional announcements. Delisting and risk alerts are documented across 16 exchanges. Evaluate the coverage and event data alongside arrival times. Use the results from your own server to decide whether the feed fits your listing bot.
