// Install: npm install ccai-node
import { CCAI } from 'ccai-node';

const ccai = new CCAI({
  clientId: process.env.CCAI_CLIENT_ID,
  apiKey: process.env.CCAI_API_KEY
});

// Validate a single email address
const result = await ccai.contactValidator.validateEmail('[email protected]');

console.log(result.status);
// "valid" | "invalid" | "risky"

if (result.status === 'valid') {
  // Safe to add to your campaign
  addToEmailCampaign(result.contactField);
}

// Validate up to 50 emails at once
const results = await ccai.contactValidator.validateEmails([
  '[email protected]',
  '[email protected]',
  '[email protected]',
  '[email protected]'
]);

console.log(results.summary);
// { total: 4, valid: 2, invalid: 1, risky: 1, landline: 0 }

// Filter to only valid emails for your campaign
const validEmails = results.results
  .filter(r => r.status === 'valid')
  .map(r => r.contactField);

console.log(`Sending to ${validEmails.length} verified addresses`);

// Validate a single phone number (E.164 format)
const result = await ccai.contactValidator.validatePhone(
  '+15551234567',
  'US'
);

console.log(result.status);
// "valid" | "invalid" | "landline"

if (result.status === 'valid') {
  // Mobile number — safe to send SMS
  addToSMSCampaign(result.contactField);
} else if (result.status === 'landline') {
  // Cannot receive SMS — skip
  console.log('Landline detected, skipping SMS');
}

// Validate up to 50 phone numbers at once
const results = await ccai.contactValidator.validatePhones([
  { phone: '+15551234567' },
  { phone: '+15559876543', countryCode: 'US' },
  { phone: '+15550000000' }

Why Validate Before You Send?

Reduce Bounce Rates

High email bounce rates hurt your sender reputation. Validate before every campaign to keep your list clean.

Avoid SMS Waste

Sending to landlines and invalid numbers burns credits. Bulk validate your list before launching SMS campaigns.

Protect Deliverability

ISPs and carriers penalize senders with high invalid rates. Validation keeps your deliverability score healthy.

Automate List Hygiene

Integrate validation into your signup flow or CRM sync to automatically filter bad contacts before they enter your list.
