Overview

Real Time Finance is a WebSocket API that streams live stock prices, trade data, and market events directly to your application with minimal latency. Unlike REST APIs that require polling, WebSocket connections push data to you as it happens, making it ideal for live dashboards or trading tools. An API key is required; connect using a WebSocket client and subscribe to the ticker symbols you want.

Beginner Tip

WebSocket APIs differ from REST — you open a persistent connection and receive data as a continuous stream instead of making individual requests. Use a library like ws (Node.js) or websockets (Python) to handle the connection lifecycle.

Available Data

stock price and symbol

open/close/high/low values

trading volume

market cap

historical price data

Example Response

JSON Response

{
  "status": "success",
  "data": {
    "result": "Data from Real Time Finance",
    "description": "Websocket API to access realtime stock data",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

symbol The stock ticker symbol for this data point (e.g., "AAPL").

price Current trade or bid price of the asset.

timestamp Unix timestamp (milliseconds) when this data was generated.

volume Trading volume associated with this price update.

type Message type such as "trade" or "quote", indicating the event category.

Implementation Example

Request

const url = "https://github.com/Real-time-finance/finance-websocket-API/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

What Can You Build?

Common Errors & Troubleshooting

Connection refused / 401 Unauthorized Missing or invalid API key in the WebSocket handshake.

✓ Include your API key as a query parameter or in the connection headers as specified in the documentation.

Connection drops unexpectedly The server closes idle connections after a timeout period.

✓ Implement a heartbeat/ping mechanism in your client to keep the connection alive.

No data received after subscribing Subscription message format is incorrect or the ticker symbol is invalid.

✓ Send the subscription JSON message immediately after connection opens and verify the symbol format (e.g., "AAPL" not "AAPL.US").

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
