Production Examples

Real code examples for common domain data use cases

Domain Validation

// Check domain availability
const response = await fetch('https://api.ops.tools/v1/whois/example.com', {
  headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
});

const data = await response.json();
if (data.available) {
  console.log('Domain is available!');
} else {
  console.log('Domain expires:', data.dates.expires);
}

Validate domain availability and get registration details with a single API call. Perfect for domain registration platforms and brand protection tools.

Security Analysis

// Security screening workflow
async function screenDomain(domain) {
  const [whois, dns, ssl] = await Promise.all([
    fetchWhois(domain),
    fetchDnsRecords(domain),
    fetchSslStatus(domain)
  ]);

  return {
    riskScore: calculateRisk(whois, dns, ssl),
    trustSignals: extractSignals(whois, dns, ssl),
    recommendation: getRecommendation(riskScore)
  };
}

Combine multiple APIs for comprehensive security screening. Ideal for fraud detection, KYC processes, and enterprise security platforms.
