Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.
Enter a domain, URL, IP, email, or record and get a focused result without setup.
Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.
Use the request and response examples to turn a one-off check into an API call or recipe.
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.
Transparent docs, authenticated requests, and visible reliability details make it easier to evaluate DomScan before you ship.
OpenAPI, Swagger, Postman, CLI, SDK, and MCP links are one click away.
Authenticated endpoints use API keys with clear credit costs before you call them.
Start with 10,000 monthly credits and upgrade only when usage grows.
Start from the curl and HTTP samples, then map the parameters into your application code.
Syntax, MX, disposable, role-based
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.

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.
