Best Practices for Semantic Understanding from URL APIs in 2025

Best Practices for Semantic Understanding from URL APIs in 2025. Klazify classifies a URL — it does not scrape the page body. That is POST https://www.klazify.com/api/categorize with Bearer auth and {"url":"https://cbsnews.com"}.

Starter is $39.99/mo (500 successful calls) with a 7-day trial. Failed/unreachable calls are not billed. IAB: POST /api/domain_iab_categories. MCP: klazify.com/mcp. Register: klazify.com/register.

Request: official CBS URL

curl -X POST 'https://www.klazify.com/api/categorize' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"url": "https://cbsnews.com"}'

Response: official sample (selected)

{
  "domain": {
    "categories": [
      { "confidence": 0.97, "name": "/News" }
    ],
    "domain_url": "https://cbsnews.com"
  }
}

Pass the website you actually need classified. confidence is 0–1.
