Market Data API

CoinAPI’s Cryptocurrency Data API Guide

This guide offers a concise overview of CoinAPI’s cryptocurrency data API, detailing offerings from real-time exchange rates to historical data. It equips you with the necessary insights to effectively analyze the crypto market using this comprehensive tool.

Real-Time exchange rates

At CoinAPI, our crypto exchange rates, a key aspect of Market Data API, are calculated using the 24-hour Volume Weighted Average Price (VWAP-24H). This calculation is derived from a variety of high-quality data sources, with a specific focus on “SPOT” data types. We meticulously exclude any data from sources that are not deemed legitimate. Our approach involves a combination of quotes, trades, and metadata datasets, applying strict criteria for spreads in quotes and placing a strong emphasis on midpoint data for accurate pricing.

Trade volumes are integral to our VWAP24 algorithm, another component of CoinAPI’s cryptocurrency data API. We give utmost priority to data freshness, updating the last 24-hour volume for each symbol every 4 hours and ensuring continuous updates every second. The algorithm is further enhanced with statistical filtering and a preference for high-ranking exchanges, ensuring the provision of the highest quality data. Lastly, we utilize a tree structure based on the VWAP24 data to determine the final exchange rates, guaranteeing that our users have access to the most current and accurate exchange rates as part of CoinAPI’s cryptocurrency data API.

Quotes

Quotes are crucial for traders and investors who depend on current information for making informed decisions. They typically include bid and ask prices, providing a snapshot of the current market demand and supply, and are a vital tool for assessing the market. In cryptocurrency, quotes are particularly important for algorithmic trading, where accuracy and speed are essential. They also form the basis for market analysis, aiding in identifying trends and gauging market sentiment. Additionally, quotes are used as reference points for executing trades, ensuring that transactions reflect the latest market conditions.

Crypto OHLCV data (Open, High, Low, Close, Volume)

OHLCV data is a comprehensive summary of market activity within a specific timeframe, capturing crucial market movement aspects. This data is fundamental to technical analysis, helping traders identify market trends and patterns and providing insights into market psychology and potential future movements. It’s widely used in charting for visualizing market trends, creating trading indicators like moving averages and Bollinger Bands, and backtesting trading strategies.

CoinAPI offers OHLCV updates for each symbol, with periods from 1SEC to 1MIN. Updates are sent when a period closes or every 5 seconds if the period has been updated but not closed, ensuring users have timely and accurate data for analysis and decision-making.

Traders use this information to gauge market sentiment, develop hedging strategies, and perform comprehensive risk assessments, making it an invaluable tool for informed decision-making in the dynamic world of derivatives trading.

Liquidations

Liquidations in trading occur when an exchange forcibly closes a trader’s position due to their margin balance falling below the required maintenance margin, a measure to maintain the trading system’s integrity. These events are significant indicators of market volatility and the level of risk traders are taking on. High volumes of liquidations typically suggest extreme market conditions and can signal impending shifts in market dynamics.

This data is vital for thorough market analysis, aiding in evaluating market sentiment, identifying potential reversal points, and forming part of effective risk management strategies. Understanding trends in liquidations allows traders and analysts to gain valuable insights into current market conditions, enabling them to tailor their strategies more effectively.

Trade volume data

Trade volume data measures the total cryptocurrency traded on an exchange within a specific period, acting as a key indicator of the exchange’s liquidity and the overall activity in the market. Its significance lies in its ability to reflect market dynamics; high trade volumes often correlate with heightened market activity and can signal the strength or importance of price movements. In market analysis, trade volume data is crucial for identifying trends, confirming chart patterns, and understanding supply and demand dynamics. Both analysts and traders depend on this data for informed decision-making, as it offers essential insights into market momentum and potential future trends.

CoinAPI’s blend of speed, precision, and thoroughness makes its latest quotes data a critical tool for traders and analysts in the ever-evolving cryptocurrency market.

Raw data

CoinAPI distinguishes between aggregated and raw data types to cater to diverse data analysis needs. Aggregated data types, such as OHLCV and Exchange Rates, require a specific period for aggregation, with our datasets starting from a minimum interval of 1 second. On the other hand, raw data types represent the pinnacle of real-time information, capturing every market nuance as it happens. This unaggregated, real-time data is disseminated continuously, ensuring that every update is promptly available. For those seeking the most granular level of market data, our historical API and flat files offer tick-by-tick data, accessible through our dedicated platform, Cryptotick.com.

Providing the most detailed and granular data, raw data types are particularly valuable for custom analysis and the development of unique trading algorithms. Institutions and advanced traders leverage this data for conducting comprehensive market analysis, developing proprietary trading models, and for extensive research purposes. This level of detail and immediacy in data provision makes CoinAPI an essential resource for those requiring in-depth, real-time market insights.

Flat files

CoinAPI’s Flat Files S3 API, a vital part of CoinAPI Cryptocurrency Data Types, is a RESTful interface designed for seamless access to data stored in flat file formats. This API is in line with Amazon S3 standards, offering the flexibility to integrate with existing Amazon S3-based infrastructure. While it shares similarities with Amazon S3, the Flat Files S3 API is specifically tailored for listing and downloading files, and does not cover the entire spectrum of Amazon S3 features. This specialized approach ensures that users can efficiently manage their data retrieval needs, a key aspect of utilizing CoinAPI Cryptocurrency Data Types, especially when accessing and downloading the extensive data archives provided by CoinAPI.

Crypto index data

Our another product is Indexes API which gives you comprehensive access to historical and real-time crypto index data. You can access more than 7k indexes and 2k assets as well as create your custom index. Indices are the proper way to research the overall cryptocurrency market performance or its segment. They are also a way to attract non-crypto investors because of the simplified and accessible investment process that doesn't require researching and selecting individual cryptocurrencies.

CoinAPI provides crypto index data in various formats, including JSON, CSV, and XML. The data typically includes information such as the index name, timestamp, value, and other relevant metrics that are part of the index calculation.
