DomScan

About DomScan

DomScan is an API and MCP server that provides domain, DNS, web, security, and identity intelligence through a catalog of products including WHOIS lookup, RDAP lookup, domain availability, DNS lookup, SSL certificate checks, email authentication and verification, subdomain finder, security headers, domain reputation, typosquatting detection, web scraping, tech stack detection, SEO auditing, and website screenshots. Products are organized into suites covering web data, domain intelligence, DNS and infrastructure, security and trust, identity and verification, and monitoring and automation. The identity and verification suite checks public contact, organization, social-handle, and website-declared signals, and does not perform KYC or prove legal identity.

Requests can be run individually or combined into workflows, with a published credit cost and execution limit for each operation. The platform offers 62 products, 171 endpoints, and 105 MCP tools, accessible via API, SDKs, a CLI, and an OpenAPI/Swagger/Postman reference. It is aimed at developers and teams building products or agents that need to turn public internet signals into structured data for decisions such as domain research, infrastructure mapping, and security or reputation assessment.

A free tier includes 10,000 credits per month, with a dashboard for API keys, usage logs, billing, and team members.
