APIs are one of the internet’s secret engines. But What Is API With an Example? Give an example and tell me why you should care. You may not have known it, but you’ve already used an API if you’ve ever bought something online, logged into a service with Google or Facebook, or even used a crypto card like the BitLily Crypto Card.
What Is an API?
API is short for “Application Programming Interface.” It’s a bridge that lets two different software programs talk to each other in simple terms.
Think of it like a waiter at a restaurant:
- You (the user) tell the waiter (the API) what you want to eat.
- The waiter brings your order to the kitchen (the system).
- The waiter brings your food back after the kitchen makes it.
You don’t need to know how the kitchen works because the waiter (API) takes care of talking to the kitchen for you.
An API in Action
If you want to pay a freelancer on BitLily, the e-commerce site for freelancers, creators, and digital service providers, you can do so.
- You can use your BitLily Crypto Card to pay with Bitcoin.
- An API lets the BitLily platform talk to the blockchain network.
- The API quickly confirms the transaction, changes it if necessary, and updates your account balance.
It looks like a smooth payment process to you, but APIs are doing all the hard work behind the scenes.
Why APIs Are Important in Crypto
APIs are very important in the world of crypto:
- Price Data: APIs get live exchange rates, so you can see how much Bitcoin or Ethereum is worth in dollars when you use your BitLily Crypto Card.
- Wallet Integration: APIs link your BitLily wallet to the blockchain.
- Merchant Payments: Freelancers and creators on BitLily get paid right away in crypto because APIs check the payments behind the scenes.
The best part is that BitLily doesn’t need KYC to work. You don’t have to go through long verification processes to start using the platform, which makes it faster and easier for people all over the world to use.
