PumpSwap Data API

Accessing PumpSwap data requires a PumpPortal API key and linked wallet funded with at least 0.02 SOL. By streaming PumpSwap data your wallet will incur a charge of 0.01 SOL for every 10000 websocket messages you receive.

PumpSwap data is enabled only if you connect to the websocket using the following URL format:

wss://pumpportal.fun/api/data?api-key=your-api-key-here

If the wallet linked to your API key does not contain the minimum balance of SOL, the connection will be restricted to only trades on the bonding curve.

Examples:

Python

import asyncio
import websockets
import json

async def subscribe():
  uri = "wss://pumpportal.fun/api/data?api-key=your-api-key-here"
  async with websockets.connect(uri) as websocket:
      
      # Subscribing to trades made by accounts
      payload = {
          "method": "subscribeAccountTrade",
          "keys": ["AArPXm8JatJiuyEffuC1un2Sc835SULa4uQqDcaGpAjV"]  # array of accounts to watch
      }
      await websocket.send(json.dumps(payload))

      # Subscribing to trades on tokens
      payload = {
          "method": "subscribeTokenTrade",
          "keys": ["GkyPYa7NnCFbduLknCfBfP7p8564X1VZhwZYJ6CZpump"]  # array of token CAs to watch
      }
      await websocket.send(json.dumps(payload))
      
      async for message in websocket:
          print(json.loads(message))

# Run the subscribe function
asyncio.get_event_loop().run_until_complete(subscribe())

JavaScript

import WebSocket from 'ws';

const ws = new WebSocket('wss://pumpportal.fun/api/data?api-key=your-api-key-here');

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

  // Subscribing to trades made by accounts
  payload = {
      method: "subscribeAccountTrade",
      keys: ["AArPXm8JatJiuyEffuC1un2Sc835SULa4uQqDcaGpAjV"] // array of accounts to watch
    }
  ws.send(JSON.stringify(payload));

  // Subscribing to trades on tokens
  payload = {
      method: "subscribeTokenTrade",
      keys: ["GkyPYa7NnCFbduLknCfBfP7p8564X1VZhwZYJ6CZpump"] // array of token CAs to watch
    }
  ws.send(JSON.stringify(payload));
});

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

You can also unsubscribe from any data stream in the same way, using the following methods:

• unsubscribeTokenTrade

• unsubscribeAccountTrade
