### Axra: A Modern Solution

Axra positions itself as a modern, developer-friendly payment platform that offers a sophisticated payment gateway solution. Its API is designed to simplify integration, enhance security, and provide flexible customization options for businesses of all sizes.

## Understanding Payment API

### Key Features of a Payment API
- **Flexibility**: Customizable to fit various business models.
- **Security**: Incorporates industry-standard encryption and tokenization.
- **Scalability**: Supports businesses as they grow and expand.

### Practical API Integration Examples

#### JavaScript/Node.js Example
Here's a basic example of how you might use a payment API in a Node.js environment to process a payment.

```javascript
const axios = require('axios');

async function processPayment() {
try {
const response = await axios.post('https://api.axra.com/v1/payments', {
amount: 5000,
currency: 'USD',
payment_method: 'credit_card',
card_details: {
number: '4111111111111111',
expiry_month: '12',
expiry_year: '2025',
cvv: '123'
}
}, {
headers: {
'Authorization': 'Bearer YOUR_API_KEY'
}
});
console.log('Payment successful:', response.data);
} catch (error) {
console.error('Error processing payment:', error);
}
}

processPayment();
```

#### cURL Example
For testing purposes, you can use cURL to interact with the payment API.

```bash
curl -X POST https://api.axra.com/v1/payments \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"amount": 5000,
"currency": "USD",
"payment_method": "credit_card",
"card_details": {
"number": "4111111111111111",
"expiry_month": "12",
"expiry_year": "2025",
"cvv": "123"
}
}'
```

#### HTML Example
When integrating payment forms on a website, the HTML might look like this:

```html
<form id="payment-form">
<input type="text" name="card_number" placeholder="Card Number" />
<input type="text" name="expiry_date" placeholder="MM/YY" />
<input type="text" name="cvv" placeholder="CVV" />
<button type="submit">Pay Now</button>
</form>

<script>
document.getElementById('payment-form').addEventListener('submit', function(e) {
e.preventDefault();
// Add JavaScript to call the payment API
});
</script>
```
