π CoinGecko API 101:
Imagine you want to build an app that shows the latest price of Bitcoin, but you don't want to type it in manually every second. That's where an API, or Application Programming Interface, comes in! Think of it like a polite waiter who takes your order (a request for data) to the kitchen (CoinGecko's huge database) and brings back exactly what you asked for.
The CoinGecko API lets your own computer programs or websites "talk" directly to CoinGecko to get real-time information about thousands of cryptocurrencies. This includes their prices, how much they're being traded, their overall market value, and more. Developers use this "waiter" to make their apps smart and always up-to-date with the latest crypto happenings.
π Key AI Concepts Explained:
1. Data Integration: How different software systems can connect and share information with each other seamlessly.
2. Algorithmic Trading: Using pre-set rules or computer programs to automatically buy and sell cryptocurrencies based on market data.
3. Real-time Data Processing: The ability to handle and react to new information as soon as it becomes available, without delay.
π Words to Know:
1. API (Application Programming Interface): A set of rules allowing different software programs to communicate and share data.
2. Endpoint: A specific URL that an API provides for accessing particular resources or data points from its database.
