Guidelines for optimizing performance, managing costs, and building reliable integrations with the Website Categorization API.
Following these best practices ensures your integration performs optimally while minimizing costs and maximizing reliability. Whether you're building a real-time filtering system or a batch enrichment pipeline, these guidelines help you get the most from the API.
Website categories typically remain stable over time. Implement caching to reduce redundant API calls and improve response times for frequently accessed domains.
When processing multiple domains, use batch endpoints rather than individual requests. Batch processing is more efficient and cost-effective for bulk operations.
// Efficient: Batch request
POST /v1/batch/categorize
{ "domains": ["example1.com", "example2.com", "example3.com"] }
// Inefficient: Multiple individual requests
GET /v1/categorize?domain=example1.com
GET /v1/categorize?domain=example2.com
GET /v1/categorize?domain=example3.com
Ensure consistent domain formatting before API calls to maximize cache efficiency and avoid duplicate requests for the same domain.
function normalizeDomain(input) {
return input
.toLowerCase()
.replace(/^https?:\/\//, '')
.replace(/^www\./, '')
.split('/')[0];
}
// "HTTPS://WWW.Example.COM/page" → "example.com"
Network issues and transient errors happen. Implement retry logic with exponential backoff for resilient integrations.
async function fetchWithRetry(url, options, maxRetries = 3) {
for (let i = 0; i < maxRetries; i++) {
try {
const response = await fetch(url, options);
if (response.ok) return response.json();
if (response.status === 429) {
await delay(Math.pow(2, i) * 1000);
continue;
}
throw new Error(`HTTP ${response.status}`);
} catch (error) {
if (i === maxRetries - 1) throw error;
await delay(Math.pow(2, i) * 1000);
}
}
}
Monitor your API usage and implement proper rate limit handling to avoid service interruptions. See our rate limits guide for details.
Protect your API credentials to prevent unauthorized access and unexpected charges. See our authentication guide for detailed security guidance.
Apply these best practices and get the most from the API.
