### Getting Started Guide
```markdown
# Getting Started
This guide will help you make your first API request.
## 1. Get Your API Key
Sign up at [https://example.com/signup](https://example.com/signup) to get your API key.
## 2. Make Your First Request
### Using curl
```bash
curl -X GET https://api.example.com/v1/api/users \
-H "Authorization: Bearer YOUR_API_KEY"
const response = await fetch('https://api.example.com/v1/api/users', {
headers: {
'Authorization': 'Bearer YOUR_API_KEY'
}
});
const users = await response.json();
console.log(users);
import requests
response = requests.get(
'https://api.example.com/v1/api/users',
headers={'Authorization': 'Bearer YOUR_API_KEY'}
)
users = response.json()
print(users)
curl -X POST https://api.example.com/v1/api/users \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"name": "John Doe",
"email": "john@example.com"
}'
Always check the response status:
try {
const response = await fetch('https://api.example.com/v1/api/users', {
headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
});
if (!response.ok) {
const error = await response.json();
console.error('Error:', error.message);
return;
}
const data = await response.json();
console.log(data);
} catch (error) {
console.error('Network error:', error);
}
