GET /api/v1/price returns the latest USTEC candle for one timeframe.
curl "https://api.realmarketapi.com/api/v1/price?apiKey=YOUR_API_KEY&symbolCode=USTEC&timeFrame=H1"const params = new URLSearchParams({
apiKey: process.env.REALMARKETAPI_KEY,
symbolCode: "USTEC",
timeFrame: "H1",
})
const res = await fetch(`https://api.realmarketapi.com/api/v1/price?${params}`)
if (!res.ok) throw new Error(`HTTP ${res.status}`)
console.log(await res.json())import os
import requests
res = requests.get("https://api.realmarketapi.com/api/v1/price", params={

print(res.json())USTEC candles and history
GET /api/v1/candle returns the most recent USTEC candles for one timeframe.
curl "https://api.realmarketapi.com/api/v1/candle?apiKey=YOUR_API_KEY&symbolCode=USTEC&timeFrame=H1"GET /api/v1/history pages through stored candles between startTime and endTime. Needs a plan with historical data.

WebSocket streams need a plan with WebSocket access (see the table above).
// /price streams USTEC H1 candles; use /candles for the rolling window.
const ws = new WebSocket("wss://api.realmarketapi.com/price?apiKey=YOUR_API_KEY&symbolCode=USTEC&timeFrame=H1")
ws.onmessage = (event) => console.log(JSON.parse(event.data))
ws.onclose = (event) => console.log("closed", event.code, event.reason)import asyncio, json, websockets

url = "wss://api.realmarketapi.com/price?apiKey=YOUR_API_KEY&symbolCode=USTEC&timeFrame=H1"
