In the context of CoinAPI, symbol metadata refers to the comprehensive set of descriptive information associated with each trading symbol available through the API. This metadata provides essential details about the cryptocurrency pairs, enabling users to understand and interact with the market data effectively.

Key Components of Symbol Metadata

• Symbol ID (symbol_id): A unique identifier for each trading pair (e.g., BINANCE_SPOT_BTC_USD).
• Exchange ID (exchange_id): Specifies the exchange where the symbol is listed (e.g., BINANCE_SPOT).
• Symbol Type (symbol_type): Indicates the type of trading pair, such as SPOT, FUTURES, PERPETUAL, etc.
• Base Asset (asset_id_base): The primary asset in the trading pair (e.g., BTC in BTC/USD).
• Quote Asset (asset_id_quote): The secondary asset used to price the base asset (e.g., USD in BTC/USD).
• Price Precision (price_precision): The number of decimal places used for the asset's price.
• Size Precision (size_precision): The number of decimal places used for the asset's size.
• Data Start and End Dates (data_start, data_end): The time frame during which the symbol's data is available.
• Volume Metrics (volume_1hrs_usd, volume_1day_usd, volume_1mth_usd): Trading volumes over different time intervals.

Purpose

• Symbol Metadata is crucial for:
• Data Integration: Facilitates the accurate integration of market data into applications by providing detailed information about each trading pair.
• Market Analysis: Enables analysts to perform in-depth market analysis by understanding the characteristics and trading specifics of each symbol.
• Automated Trading: Assists in developing automated trading strategies by providing necessary symbol details such as precision and asset identifiers.

Integration

Developers can integrate Symbol Metadata into their applications by:

1. Fetching Metadata: Use the REST API endpoint to retrieve the latest symbol information. Example request:
   GET https://rest.coinapi.io/v1/symbols
2. Parsing Metadata: Utilize the retrieved metadata to configure trading pairs, set precision levels, and manage data streams effectively.
3. Real-Time Updates: Subscribe to WebSocket symbol messages to receive live updates, ensuring that the application adapts to any changes in symbol configurations.
