## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Domain Intelligence API

One call returns a complete dossier for any domain: registration age, DNS, SSL, technology stack, estimated site size, social profiles, and a trust score. Built for agents and analysts doing due diligence on vendors, leads, counterparties, and acquisition targets. Every input is a stable public protocol (RDAP, DNS, TLS, and one HTTP request), so it is fast, cheap, and does not break when a website changes its markup.

### Features

- Get a full domain dossier in one API call
- WHOIS and RDAP registration: age, registrar, expiry, nameservers
- DNS records with mail provider, SPF, and DMARC detection
- SSL certificate issuer and validity window
- Technology stack detection (WordPress, Shopify, Next.js, Cloudflare, and more)
- Estimated site size and social profiles
- Deterministic 0 to 100 trust score with a per signal breakdown
- Pay per domain, no subscription

### Use cases

- Vet a lead or vendor domain before enriching or reaching out
- Score counterparties in a due diligence workflow
- Detect the tech stack of a list of prospects
- Give an AI agent a domain vetting tool

### Input

| Field | Type | Description |
| --- | --- | --- |
| `domains` | array (required) | Bare domains or full URLs |

```json
{ "domains": ["stripe.com", "https://www.vercel.com"] }
```

### Output

One dossier per domain (trimmed):

```json
{
  "domain": "stripe.com",
  "registration": { "ageYears": 30.8, "registrar": "SafeNames Ltd." },
  "dns": { "hasMail": true, "hasSPF": true, "hasDMARC": true },
  "ssl": { "valid": true, "issuer": "DigiCert Inc", "daysUntilExpiry": 60 },
  "http": { "reachableHttps": true, "technologies": ["Next.js"] },
  "trust": { "score": 100 }
}
```

### Pricing: worked example

Pay per event. You are charged `intel-init` at $0.03 once and `domain-profiled` at $0.05 per domain dossier.

Profiling 10 domains triggers 1 start ($0.03) and 10 domain events ($0.50). Total: $0.53.

### How to use

1. Open the actor and click Try for free.
2. Enter one or more domains or URLs.
3. Click Start.
4. Read the consolidated dossier per domain.
5. Download as JSON, or call the API to vet domains inline in your workflow.

### FAQ

**What does the trust score mean?**
It is a heuristic from public signals (SSL validity, domain age, mail setup, HTTPS, sitemap). Use it as one input, not a security verdict.

**Do you return registrant contact details?**
No. Registrars redact those, and this actor does not attempt to bypass that.

**How is this different from a WHOIS lookup?**
It consolidates WHOIS, DNS, SSL, tech stack, site size, socials, and a trust score in one call, instead of a single record.

**Can it profile many domains at once?**
Yes. Pass an array and it profiles each, stopping cleanly at your budget cap.

**Can an AI agent run this?**
Yes. It supports agentic payments, so a due diligence agent can vet domains and pay per domain.

### API and agents

Run it from the [Apify API](https://docs.apify.com/api/v2) or let an AI agent call it. Supports agentic payments via x402 and Skyfire (pay per event, limited permissions, no Standby).

```bash
curl -X POST "https://api.apify.com/v2/acts/hereditary_model~domain-intelligence/runs?token=YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "domains": ["stripe.com"] }'
```

# Actor input Schema

## `domains` (type: `array`):

Domains to profile. Bare domains or full URLs both work (for example example.com or https://www.example.com/page). One dossier is returned per domain.

## Actor input object example

```json
{
  "domains": [
    "stripe.com",
    "vercel.com"
  ]
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "domains": [
        "stripe.com",
        "vercel.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("hereditary_model/domain-intelligence").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
