Subscribe Pair Updates (WS)

Subscribe Pair Updates: Credit Usage 0

Used to subscribe to price changes and related data of a specified pool / pair

URL

wss://api-data-v1.dbotx.com/data/ws/

Header: X-API-KEY

(Please do not disclose your API Key to anyone. If you are at risk of losing it, please refresh it.)

Notes

1. X-API-KEY can be obtained in your "Dashboard", go to check: Dashboard

2. To ensure the availability and stability of the WebSocket connection, a heartbeat subscription must be sent at least once every minute (recommended every 30–55 seconds), otherwise the system will automatically disconnect the timeout link

3. Example in NodeJS:

const WebSocket = require('ws')
function main() {
  const ws = new WebSocket('wss://api-data-v1.dbotx.com/data/ws/', {
    headers: {
      'x-api-key': 'YOUR_API_KEY',
    },
  })
  ws.on('open', () => {
    ws.send(
      JSON.stringify({
        method: 'subscribe',
        type: 'tokenInfo',
        args: {
          pair: '4N389xaQ2jRWDxpXmzwUCEnCQHDcDfprCsTqEd2taPoU',
          token: 'FMaopciCph2TyyQfo4V7sNJhVmadujCcDupefiCdpump',
        },
      })
    )
    setInterval(() => {
      ws.ping()
    }, 30000)
  })
  ws.on('message', res => {
    console.log('res:', res.toString('utf-8'))
  })
}
main()

1. Example in Python:

import asyncio
import websockets
import json

async def main():
    uri = "wss://api-data-v1.dbotx.com/data/ws/"
    headers = {"x-api-key": "YOUR_API_KEY"}
    msg = {
      method: 'subscribe',
      type: 'tokenInfo',
      args: {
        pair: '4N389xaQ2jRWDxpXmzwUCEnCQHDcDfprCsTqEd2taPoU',
        token: 'FMaopciCph2TyyQfo4V7sNJhVmadujCcDupefiCdpump',
      },
    },

    async with websockets.connect(uri, additional_headers=headers) as ws:
        await ws.send(json.dumps(msg))

        async def keep_alive():
            while True:
                await ws.ping()
                await asyncio.sleep(30)

        async def listen_for_messages():
            async for message in ws:
                print(message)

        await asyncio.gather(keep_alive(), listen_for_messages())

if name == "main":
    asyncio.run(main())
