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.

Product workflows

Embed domain checks, DNS intelligence, risk signals, or enrichment into onboarding, search, and internal tools.

Analyst automation

Replace repeated manual lookups with scheduled jobs, alerting, and reproducible investigation steps.

Clean JSON data

Use predictable fields, documented status codes, and credit costs instead of scraping provider pages.

AI and ops tooling

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 collection

Import ready-made requests for manual testing and team handoff.

SDKs and CLI

Use maintained packages and command-line workflows instead of writing boilerplate.

MCP integration

Expose 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.
