API Authentication Methods
## Comparing API Authentication Methods

APIs commonly use various authentication methods to secure access. Here's a comparison of three popular methods:

| Method | Description | Example Usage |
|  --- | --- | --- |
| **API Key** | A unique identifier passed along with API requests to authenticate the client. | `curl -H "Authorization: ApiKey your_api_key" https://api.example.com/data` |
| **OAuth 2.0** | An authorization framework that allows third-party services to exchange web resources on behalf of a user. | `curl -H "Authorization: Bearer your_access_token" https://api.example.com/data` |
| **JWT (JSON Web Token)** | A compact, URL-safe means of representing claims to be transferred between two parties. | `curl -H "Authorization: Bearer your_jwt_token" https://api.example.com/data` |


Code Samples in Multiple Languages
## Code Sample: Fetching Data from API

Here's how you can fetch data from the API using different programming languages:

| Language | Code Sample |
|  --- | --- |
| **Python** | 
```python
import requests
response = requests.get('https://api.example.com/data', headers={'Authorization': 'Bearer your_access_token'})
data = response.json()
```
 |
| **JavaScript (Node.js)** | 
```javascript
const fetch = require('node-fetch');
fetch('https://api.example.com/data', {
  method: 'GET',
  headers: { 'Authorization': 'Bearer your_access_token' }
})
.then(response => response.json())
.then(data => console.log(data));
```
 |
| **Ruby** | 
```ruby
require 'net/http'
require 'json'
uri = URI('https://api.example.com/data')
request = Net::HTTP::Get.new(uri)
request['Authorization'] = 'Bearer your_access_token'
response = Net::HTTP.start(uri.hostname, uri.port) { |http| http.request(request) }
data = JSON.parse(response.body)
```
