1

Making the API Call

With the API key, craft a request to the endpoint with required parameters.In this example, Sam is interested in a used car withVIN WP0AF2A99KS165242 and lives in ZIP code 33132.Sam has a credit score of 720.
const vin = 'WP0AF2A99KS165242'
const url = new URL(`https://taxes.vin/${vin}`)

const params = {
  zip: '33132',
  creditScore: '720',
}

url.search = new URLSearchParams(params).toString()

const headers = {
  Authorization: 'Bearer YOUR_API_KEY',
}

fetch(url, { headers }).then((r) => r.json())

Processing the Response

After receiving the response, extract the necessary information to present the taxes, fees, and loan payment calculations to Sam.
const taxes = data.payments.taxes
const fees = data.payments.fees
const loanAmount = data.payments.loanAmount
const monthlyPayment = data.payments.loanMonthlyPayment
const monthlyPaymentWithTaxes = data.payments.loanMonthlyPaymentWithTaxes

Presenting the Results

Present the taxes, fees, and loan payment calculations to Sam. Sam can now make an informed decision about the potential costs and loan payments for the vehicle.
console.log('Loan Amount:', loanAmount)
console.log('Monthly Payment (without taxes):', monthlyPayment)
console.log('Monthly Payment (with taxes):', monthlyPaymentWithTaxes)

console.log('\nTaxes:')
for (const [key, value] of Object.entries(taxes)) {
  console.log(' ', key, ': $', value)
}

console.log('\nFees:')
for (const [key, value] of Object.entries(fees)) {
  if (key === 'dmvFeesItemized') {
    console.log(' DMV Fees Itemized:')
    for (const dmvFee of value) {
      console.log(' ', dmvFee.name, ': $', dmvFee.value)
    }
  } else {
    console.log(' ', key, ': $', value)
