How API Credits Work

Every API call costs 1 credit and returns default fields: IAB categories v2 & v3, Web Filtering Categories and Personas.

Optionally, you can add enrichment data to any call. Two enrichment models are available:

Standard model — +1 credit (2 credits total per call)
Advanced model — +3 credits (4 credits total per call)
Uses a more advanced AI model for higher accuracy and richer results.
Ad-Tech Intelligence APIs — 4 credits per call (same as the advanced enrichment model)
MFA sites detection, COPPA compliance scoring, audience segmentation and carbon footprint scoring each render the page in a real browser and run AI content analysis, so they are billed at 4 credits per call.

Example — 100 websites

Default fields only 100 credits
+ enrichment (standard) 200 credits
+ enrichment (advanced) 400 credits

Frequently Asked Questions

Get answers to common questions about our API and database solutions.

What is the difference between Enterprise Solutions with multiple categories and Enterprise Solutions 30M and 102M?

The standard Enterprise Solutions (30M and 102M) assign one primary category to each domain, focusing on the main content and purpose of the website. The Enterprise Solution 40M with Multiple Categories provides up to 3 different categories per domain, offering a more nuanced understanding. For example, a news website might be categorized as "News & Politics" (primary), "Entertainment" (secondary), and "Sports" (tertiary), capturing the full breadth of its content. This multi-category approach is ideal for applications requiring deeper content analysis, such as advanced content filtering, sophisticated ad targeting, or comprehensive competitive intelligence.

How current is the categorization data?

Our database is updated quarterly with fresh categorization data including Global Popularity Rank Group and Country Popularity Rank Group (CrUX). The multi-category database contains 40 million domains representing the most stable and trafficked websites on the internet, with millions sourced from Google Chrome UX Report for maximum relevance and accuracy.

What file formats are supported?

We provide data in CSV format for maximum compatibility. Each record includes domain, categorization data, confidence scores, Global and Country Popularity Rank Groups (CrUX), and enrichment fields. Custom formats available for enterprise customers upon request.

Can I get subsets of the database?

Yes, we offer country-specific subsets, industry-focused datasets, and custom filtered versions based on specific IAB categories or other criteria. Contact our enterprise team for custom data requirements.

Is technical support included?

Enterprise customers receive priority technical support, integration assistance, and consultation on optimal database utilization. We also provide documentation and implementation guides for faster deployment.

How does licensing work?

Our database is licensed for internal use within your organization. You may deploy across multiple systems and environments. Redistribution requires separate licensing agreements.

What payment methods do you accept?

We accept PayPal, major credit cards, and bank transfers (SWIFT/SEPA). Enterprise customers can arrange purchase orders and invoice payments. All prices listed in USD.

Do purchased credits require an active subscription?

Yes. An active monthly subscription is required to use any credits, including purchased credit packs. If your subscription is cancelled or expires, all remaining credits — including purchased credits — become inaccessible until the subscription is reactivated. Purchased credits expire 12 months after purchase.

When do I receive the database?

The database is available as instant download after we receive the payment.

Do you offer data updates or refreshes?

Yes, we provide quarterly database updates for enterprise customers. Updated datasets include newly categorized domains and refreshed classifications for existing entries to maintain accuracy over time.
