What is Pump Fun API?

A 3rd-Party API secure endpoints that give you the opportunity to trade tokens, request liquidity information, implement stop loss and take profit strategies, and connect to streams

Our Trading API is gated by an API key and charges a 0.1% fee per trade. API keys can be created at api-pump.fun

The following methods are available:

Live stream

Stream real-time trading and token creation data by connecting to the PumpPortal Websocket at wss://rpc.api-pump.fun/ws.

Once you connect, you can subscribe to different data streams. The following methods are available:

• subscribeNewPools For token creation events.

• subscribeToken For all trades made on specific token(s).

• subscribeAccount For all trades made by specific account(s).

• subscribeTrades For all trades on pump.fun.

• subscribePublications For completed bonding curve events (publication on Raydium).

Examples:

import WebSocket from 'ws';

const ws = new WebSocket('wss://rpc.api-pump.fun/ws');  

ws.on('open', function open() {

      // Subscribing to all pump.fun trades
      payload = {
          method: "subscribeTrades",
          params: []
        }
      ws.send(JSON.stringify(payload));

      // Subscribing to new pools
      payload = {
          method: "subscribeNewPools",
          keys: []
        }
      ws.send(JSON.stringify(payload));

     // Subscribing to trades on specific mint
      payload = {
          method: "subscribeToken",
          params: ["8LPjGAPtCywvo51UACHxDg3ygzbrm9qi2XxhB2Ropump"]
        }
      ws.send(JSON.stringify(payload));
});

ws.on('message', function message(data) {
      console.log(JSON.parse(data));
});
