Styvio API

Overview

Styvio is an API provider specializing in financial market data, established in 2022. It offers developers and quantitative analysts access to a range of data types, including real-time and historical information for stocks, options, forex, and cryptocurrencies. The platform is designed to support the development of trading applications, quantitative analysis models, and portfolio management tools by providing structured access to market movements and historical trends.

The core products offered by Styvio include dedicated APIs for distinct market segments. The real-time stock data API delivers current pricing and trading information, which can be critical for applications requiring immediate market insights. Historical stock data APIs provide access to past price movements and trading volumes, essential for backtesting strategies and conducting trend analysis. For derivatives, Styvio offers an options data API, supplying details on contracts, strike prices, and expiration dates. Additionally, it provides forex data APIs for currency exchange rates and crypto data APIs for various digital assets, catering to a broad spectrum of financial markets.

Styvio aims to simplify the integration process through its developer experience, offering comprehensive documentation and API references. It provides SDKs for popular programming languages such as Python, Node.js, and Go, which can streamline the coding process and reduce implementation time. A free tier is available, allowing users to make up to 50 API requests per day, which is suitable for initial testing, proof-of-concept development, or small-scale, non-commercial projects. This accessibility enables developers to evaluate the API's suitability for their specific use cases before committing to a paid plan. Styvio's compliance with GDPR addresses data privacy considerations for users operating within the European Union.

For developers building trading platforms or analytical tools, access to reliable and timely financial data is paramount. The Styvio API facilitates this by providing endpoints that deliver structured JSON responses, allowing for programmatic consumption of market information. Whether the objective is to display live stock quotes, analyze historical performance, or power automated trading algorithms, Styvio offers the data streams necessary for such financial applications. The clarity of its API reference and the availability of language-specific SDKs contribute to a developer-friendly environment, distinguishing it from general-purpose data providers by focusing specifically on the financial domain.

Getting started

To begin using Styvio's API, you typically need to sign up for an API key through their developer portal. Once you have an API key, you can make requests to various endpoints to retrieve financial data. The following Python example demonstrates how to fetch the latest stock price for Apple (AAPL) using the requests library, which is a common method for interacting with RESTful APIs. This example assumes you have replaced YOUR_API_KEY with your actual key obtained from the Styvio dashboard.

import requests

API_KEY = 'YOUR_API_KEY' # Replace with your actual Styvio API key
SYMBOL = 'AAPL'

def get_latest_stock_price(symbol, api_key):
    base_url = 'https://api.styvio.com/v1/stock/quote'
    params = {
        'symbol': symbol,
        'apikey': api_key
    }
    try:
        response = requests.get(base_url, params=params)
        response.raise_for_status() # Raise an exception for HTTP errors
        data = response.json()
        if data and 'price' in data:
            print(f"Latest price for {symbol}: ${data['price']:.2f}")
        else:
            print(f"Could not retrieve price for {symbol}: {data}")
    except requests.exceptions.RequestException as e:
        print(f"Error fetching data for {symbol}: {e}")

if __name__ == "__main__":
    get_latest_stock_price(SYMBOL, API_KEY)

This Python code snippet illustrates a basic API call to retrieve real-time stock quotes.
