🚩 Playground

This form opens a real WebSocket connection, sends the selected JSON, and shows incoming messages. You can change the endpoint, payload, and experiment with subscriptions:

wss://api2.yodao.io

🚧 Getting data over WebSocket with JS

Choose a unique id (for example, your wallet public key). Use it both in the URL and in the message body.
Open WebSocket: wss://api2.yodao.io/?id=<YOUR_ID>. The id query param is required.
After the connection opens, send a subscription JSON to the desired channel with the same id in data.id.
The server sends { "type": "ping" } every ~30 seconds. Reply with { "type": "pong" } to keep the connection alive.

View Code

javascript

const userId = 'wallet_pubkey_or_any_id'
const wsUrl = new URL('wss://api2.yodao.io')
wsUrl.searchParams.set('id', userId)
const ws = new WebSocket(wsUrl)

// open websocket connection
ws.addEventListener('open', () => {
const payload = {
  // event we want to subscribe to
  // e.g. 'update_pools_info' – latest 50 tokens from New, Completing, Completed
  event: 'update_pools_info',
  data: {
    // action: subscribe
    action: 'subscribe',

    // Your unique identifier (wallet address or custom ID), 
    // which you've passed as x-socket-id to meme tables route,
    // if you need real-time updates for meme tables
    id: userId
  }
}

// send subscription
ws.send(JSON.stringify(payload))

// subscribe to additional channels in the same connection—no need for extra sockets
})

// handle incoming messages
ws.addEventListener('message', (event) => {
const incoming = JSON.parse(event.data)

// reply to server ping to keep the connection open
if (incoming?.type === 'ping') {
  ws.send(JSON.stringify({ type: 'pong' }))
  console.log('→ sent pong')
  return
}

console.log('New message', incoming)
})

// To unsubscribe from any channel send __STRING_0__
function unsubscribe() {
ws.send(
  JSON.stringify({
    event: 'update_pools_info',
    data: {
      // action: unsubscribe
      action: 'unsubscribe',
      id: 'docs-demo'
    }
  })
)
}

// Cleanup on page unload
window.addEventListener('beforeunload', () => ws.close())

Caution

Do not open a new WebSocket for every subscription message. Otherwise we’ll have to block you—contact us to unblock.
