About

The Companies API is a comprehensive company enrichment platform that provides developers and marketers with access to detailed profiles of over 18 million companies worldwide. Through its RESTful API, users can search for companies by domain or name, enrich company data with over 50 attributes, including industry, revenue, employee count, technologies used, and social media links, and identify similar businesses to enhance lead generation and market segmentation. It utilizes AI models and data extraction algorithms to continuously update its database, ensuring access to the most current company information. Users can also create and manage dynamic lists, receive real-time notifications when new companies match their criteria, and integrate the API seamlessly into their CRM, marketing, or product tools. The Companies API offers flexible pricing plans to accommodate various usage needs, from startups to enterprises.

About

afterSpark is a B2B company intelligence platform for researching businesses, building target-account audiences, and enriching company records. Users filter company lists by geography, industry, employee range, and revenue, preview audiences, and export matched companies. Company lookups return firmographics such as industry classifications, employee and revenue ranges, locations, and parent-child domain relationships. Free tools match company names to domains or LinkedIn pages and enrich domains with firmographics. Developers can use APIs for company lookups, IP-to-company resolution, domain relationships, and industry classification, plus MCP access for AI tools and agents. A Chrome extension displays company intelligence while browsing. Marketing agencies, sales and marketing teams, developers, and AI builders can use afterSpark for account research, audience development, data enrichment, and automated workflows.
