Interactive intelligence tool
Run the check, then ship the workflow
Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.
Review decision-ready signals
Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.
Automate the workflow that works
Use the request and response examples to turn a one-off check into an API call or recipe.

What this tool helps you decide
Each page is shaped around a practical operational question, not just a raw lookup.
See the current DNS, registration, security, pricing, or reputation evidence.
Compare the result with related checks so the next move is easier to trust.
Copy examples, open linked tools, or move into API documentation when you need scale.
Trust signals before you integrate
Transparent docs, authenticated requests, and visible reliability details make it easier to evaluate DomScan before you ship.
Live
Service status
Check live service health and documented failure responses before you integrate.
OpenAPI
API artifacts
OpenAPI, Swagger, Postman, CLI, SDK, and MCP links are one click away.
API keys
Protected access
Authenticated endpoints use API keys with clear credit costs before you call them.

quality score
The quality score (0-100) is based on multiple factors: valid syntax (+), MX records present (+), not disposable (+), not role-based (+), clean DNS reputation (+), strong domain authentication (+), and low-risk local/domain signals (+). Deductions apply for issues like disposable domains (-40), no MX records (-50), role-based addresses (-15), suspicious local parts, reserved domains, or blacklist hits.

Frequently asked questions
What is email verification?
Email verification checks whether an email address has a valid format and a domain that can receive mail. It verifies MX records, detects disposable domains, reviews role-based addresses, checks DNS reputation, and scores delivery risk without mailbox-level SMTP probing.
How is the quality score calculated?
The quality score (0-100) is based on multiple factors: valid syntax (+), MX records present (+), not disposable (+), not role-based (+), clean DNS reputation (+), strong domain authentication (+), and low-risk local/domain signals (+). Deductions apply for issues like disposable domains (-40), no MX records (-50), role-based addresses (-15), suspicious local parts, reserved domains, or blacklist hits.
