The US Street API is an essential tool for businesses and developers looking to ensure the accuracy and completeness of US postal addresses. By validating and appending data, this API enhances the quality of address data, helping reduce delivery errors and ensuring efficient shipping processes. Whether you're managing an e-commerce platform or a customer relationship management (CRM) system, having accurate address information is crucial. With features that allow for real-time validation and the ability to append missing address components like city, state, and ZIP codes, this API streamlines operations and improves customer satisfaction.

Integrating the US Street API into your application provides numerous benefits, including the following:

• Accurate address validation to eliminate typographical errors.
• Enhanced data quality with appended address components.
• Reduction of delivery costs through improved address accuracy.
• Increased customer trust and satisfaction with reliable shipping information.
• Seamless integration into existing workflows and databases.

Here is a JavaScript code example for calling the US Street API:

const axios = require('axios');

const validateAddress = async (address) => {
    try {
        const response = await axios.get('https://api.smarty.com/street-address/validate', {
            params: {
                address: address,
                key: 'YOUR_API_KEY' // Replace with your Smarty API key
            }
        });
        console.log(response.data);
    } catch (error) {
        console.error('Error validating address:', error);
    }
};

validateAddress('1600 Amphitheatre Parkway, Mountain View, CA');
