The Metals-API is a robust platform that empowers developers to build next-generation applications focused on precious metals trading. With its extensive capabilities, the API provides access to real-time and historical data for various metals, including gold, silver, platinum, and palladium. The API's design emphasizes innovation and technological advancement, making it an essential tool for anyone involved in the precious metals market.

One of the standout features of the Metals-API is its ability to deliver real-time exchange rate data. Depending on your subscription plan, the API's latest rates endpoint can return data updated every 60 minutes, every 10 minutes, or even more frequently. This ensures that users have access to the most current market information, which is critical for making timely trading decisions.

In addition to real-time data, the Metals-API offers a historical rates endpoint that allows users to query historical prices dating back to 2019. This feature is particularly useful for analyzing trends over time and understanding how external factors influence gold prices. By appending a specific date to the API request, users can retrieve historical rates for any given day.

The API also includes a bid and ask endpoint, which provides real-time bid and ask prices for metals. This feature is invaluable for traders looking to execute orders at the best possible prices. The convert endpoint allows users to convert amounts from one metal to another or to/from USD, facilitating seamless transactions across different currencies.

For those interested in tracking price movements over time, the time-series endpoint allows users to query daily historical rates between two dates of their choice. This functionality is essential for conducting thorough analyses and understanding market dynamics. Additionally, the fluctuation endpoint provides insights into how prices change on a day-to-day basis, helping traders identify patterns and make informed decisions.

The Metals-API also offers a carat endpoint, which allows users to retrieve gold rates by carat. This feature is particularly useful for jewelers and consumers looking to understand the value of gold in different forms. Furthermore, the lowest/highest price endpoint enables users to query the API for the lowest and highest prices within a specified timeframe, providing a comprehensive view of market performance.
