DomScan is an internet intelligence API platform that collects web data, investigates domain infrastructure, assesses security signals, and automates monitoring workflows. It offers six product suites: Web Data parses web pages into structured formats; Domain Intelligence tracks domain availability, ownership, and valuation; DNS and Infrastructure analyzes subdomains and DNS records; Security and Trust evaluates risks, reputation, and SSL validity; Identity and Verification extracts public contact details; Monitoring and Automation manages watchlists and batch processing. The platform indicates data certainty in responses, distinguishing between observed, absent, unknown, and unsupported outcomes. DomScan provides REST APIs, SDKs, MCP tool compatibility, and a command-line interface. All features operate with a single API key and usage-based credit pricing, with each operation specifying its cost, inputs, and response formats.
