Quick examples

Clients for both the REST API and streaming WebSocket API are included. Private endpoints as indicated in the API docs require authentication with an API key and secret key.

REST API example:

import Gemini from 'gemini-api-node'

const gemini = new Gemini({ key, secret, sandbox: false })
gemini.getOrderBook('btcusd', { limit_asks: 10, limit_bids: 10 })
  .then(console.log)
  .catch(console.error)

WebSocket API examples:

import Gemini from 'gemini-api-node'

const gemini = new Gemini()
let ws = gemini.newWebSocketMarketData('btcusd', { 'top_of_book' : 'true', 'offers': true })

ws.onopen = () => {
  console.log('Websocket is open')
}
  
ws.onmessage = (message) => {
  let data = JSON.parse(message.data)
  console.log('Websocket data received')
}
import Gemini from 'gemini-api-node'

const gemini = new Gemini({ key, secret, sandbox: true })
let ws = gemini.newWebSocketOrderEvents({ symbolFilter: ['btcusd'], eventTypeFilter: ['fill', 'closed']})

ws.onopen = () => {
  console.log('Websocket is open')
}
  
ws.onmessage = (message) => {
  let data = JSON.parse(message.data)
  console.log('Websocket data received')
}
