What Website Categorization API is
Website Categorization API classifies websites in real time through API and web access, and provides a downloadable database of up to 120 million domains. The API returns more than 15 data fields per request with stated response times under 100 ms. Supported taxonomies include IAB v2 and v3, IPTC NewsCodes, Google Shopping, Shopify, Amazon, eBay, and web content filtering. Enrichment covers sentiment, personas, topics, keywords, entities, and competitors; API plans also list phishing-domain and malware detection. The domain database is offered in CSV, JSON, SQLite, and other enterprise formats under a perpetual license, with optional annual refreshes. Integrations use HTTPS POST, with examples for Python, JavaScript, Ruby, and C#. Each call costs one credit by default, with extra credits for enrichment and specialized analyses. Plans start at $99 a month for 10,000 API credits or MCP lookups. Purchased credits require an active monthly subscription and expire after 12 months. A no-card demo is available.
