Deepline Native: Domain Health Check

Checking whether a company domain resolves, follows redirects to a canonical domain, returns 404/410, or is merely blocked by Cloudflare/Akamai before running.

Tool ID: domain_health_check

Run this action

Use the TypeScript SDK for a single call. Put ctx.tools.execute(...) inside a Play when the call should be durable, scheduled, or run across a CSV.

import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'domain_health_check',
  {
    "domain": "example.com"
  },
);

console.log(result.toolResponse.raw);

CLI

deepline tools execute domain_health_check --input '{
  "domain": "example.com"
}' --json

Example response

The SDK exposes this shape at result.toolResponse.raw. Values below are representative.

{
  "input_domain": "example.com",
  "input_url": "https://example.com",
  "status": "live",
  "http_status": 1,
  "final_url": "https://example.com",
  "final_domain": "example.com",
  "redirected": true,
  "canonical_url": "https://example.com",
  "page_title": "example",
  "response_server": "example",
  "protection_detected": true,
  "attempts": [
    {
      "method": "HEAD",
      "url": "https://example.com",
      "status": 1,
      "location": "example",
      "error": "example"
    }
  ]
}

Use deepline tools get domain_health_check --json for the latest machine-readable contract.

Input reference

Check whether a domain resolves to a live website, follows redirects to a canonical domain, or returns a not-found/unreachable status. Use before company contact search to catch stale domains such as old .io domains that moved to .com.

Name	Type	Required	Default	Details
`payload.domain`	`string`	Yes	—	Domain or URL to probe. The action normalizes to a root hostname, tries HTTPS then HTTP, follows redirects, and refuses localhost/private IP targets. Minimum length: 1.
`payload.timeout_ms`	`integer`	No	`5000`	Per-request timeout in milliseconds. Minimum: 1000. Maximum: 10000.
`payload.fallback_get`	`boolean`	No	`false`	When true, retry with GET only when HEAD is explicitly unsupported (405/501). The probe never retries GET after Cloudflare/protection blocks.

Output reference

Domain health and redirect resolution result. final_domain is the value to prefer as canonical_domain when status is live or redirected.
