}One platform, several ways to use it
Move from exploration to production without rebuilding the decision model around separate catalogs.
One API key
Use one account and authentication model across the public product catalog.
Usage-based credits
Each operation publishes its credit cost. Multi-step and high-depth work can cost more than a basic check.
REST APIs
Call focused endpoints with documented inputs, response shapes, errors, and credit behavior.
MCP tools
Let compatible agents discover and call supported DomScan operations with structured inputs.
SDK-ready contracts
Use maintained contracts and examples to integrate from common application environments.
Bulk and asynchronous options
Queue supported GET requests in batches of up to 100, or use product-specific bulk and job endpoints where listed.
Give your AI domain expertise
Connect DomScan to Claude, ChatGPT, Cursor, or any MCP-compatible AI. One config, instant domain intelligence.

}Evidence before certainty
DomScan distinguishes observed, absent, unknown, not requested, and unsupported outcomes when the product contract supports them.
Stable product contracts
Product and endpoint pages publish the supported inputs, response shapes, execution modes, and credit behavior.
Examples tied to the docs
Marketing examples lead to the exact API documentation instead of substituting for the contract.
Limits stay visible
Redacted records, incomplete sources, blocked checks, and mode-specific coverage are reported as limitations rather than hidden.
Unknown stays unknown
Inconclusive, rate-limited, timeout, unsupported, or unavailable checks are not presented as absent, safe, or claimable.
Built for teams that need explainable internet evidence
Choose a product or workflow based on the decision your team owns.
Developers
Add focused internet data to product flows with stable endpoints and machine-readable responses.
Security teams
Triage brand, domain, DNS, certificate, reputation, email-control, and passive vulnerability signals.
Growth and research teams
Collect public pages, understand websites and companies, compare domains, and build review queues.
Domain professionals
Research availability, records, lifecycle, pricing, valuation, portfolio health, and related candidates.
Agent builders
Give agents bounded web and internet context through REST or supported MCP tools.
Start with the decision, then price the operations
A focused check can cost one credit. Rendering, deep analysis, multi-product recipes, and larger jobs consume the published cost of the work requested.
