Trust signals before you integrate
Transparent docs, authenticated requests, and visible reliability details make it easier to evaluate DomScan before you ship.
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.
10,000
Free allowance
Start with 10,000 monthly credits and upgrade only when usage grows.
What this API helps you ship
Use this page as a production brief: endpoints, examples, response shape, and the workflow pieces needed to plug DomScan into your own product.
Embed domain checks, DNS intelligence, risk signals, or enrichment into onboarding, search, and internal tools.
Replace repeated manual lookups with scheduled jobs, alerting, and reproducible investigation steps.
Use predictable fields, documented status codes, and credit costs instead of scraping provider pages.
Feed agents, dashboards, SOAR playbooks, and CRMs through OpenAPI, SDK, Postman, or MCP.
Integration workflow
A simple path from first request to repeatable production usage.
Authenticate once
Send your API key with the documented header and keep requests consistent across services.
Query with examples
Start from the curl and HTTP samples, then map the parameters into your application code.
Operate and monitor
Use status codes, credit costs, and response fields to build retries, logs, and alerts.
Developer kit
Jump from this page into machine-readable docs, request collections, SDKs, or agent tooling.
OpenAPI schema
Generate clients or inspect every request and response shape.
Postman collectionImport ready-made requests for manual testing and team handoff.
SDKs and CLIUse maintained packages and command-line workflows instead of writing boilerplate.
MCP integrationExpose domain intelligence to AI agents and internal assistant workflows.
Parameters and response map
Scan the inputs, output fields, and status codes before wiring the endpoint into your client.

}Frequently Asked Questions
How is reputation score calculated?
Score combines multiple factors: domain age, blacklist status, SSL configuration, DNS setup, historical behavior, and threat intelligence feeds. Higher scores indicate greater trustworthiness.
How often is data updated?
Blacklist and threat intelligence data is updated multiple times per day. Historical data and domain age are calculated in real-time.
Can a domain improve its score?
Yes. Domains can improve reputation by maintaining clean history over time, proper SSL configuration, and avoiding association with malicious activity.
What blacklists do you check?
We check 15+ major security blacklists including Spamhaus, SURBL, URIBL, PhishTank, Google Safe Browsing, and others.
