## 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

## AI Crawler Access Checker

Check which known AI crawlers a domain's `robots.txt` policy allows or blocks.

### What it checks

- `robots.txt` rules for named AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, and others)
- Whether `robots.txt` itself is reachable and parseable

**This reports declared policy only, not traffic.** It does not measure or infer whether any crawler has crawled the domain — only what the domain's `robots.txt` currently permits or disallows.

### Pricing

**This is a paid, pay-per-event Actor: $0.03 per completed check.**

Exactly one `crawler-access-check` event is charged per run, only after a real result exists (`success` or a useful `partial`). There is no charge for invalid input, a target blocked by the public-network policy, or a run that fails before a result is produced.

### Input

- `domain` (required): a public domain or HTTPS origin to check, e.g. `example.com`.

Example input:

```json
{
  "domain": "example.com"
}
```

### Output

The default dataset receives one result envelope per domain; `RUN_SUMMARY` in the default key-value store records processing, delivery, billing, and dependency totals.

Representative abbreviated output:

```json
{
  "status": "success",
  "target": {"identifier": "example.com"},
  "result": {
    "domain": "example.com",
    "crawlers": {"GPTBot": "blocked", "ClaudeBot": "allowed", "PerplexityBot": "allowed"},
    "robotsUrl": "https://example.com/robots.txt"
  }
}
```

`restricted` means API-IFY rejected the target locally before calling Verify. `unreachable` means the domain could not be reached. `dependency_unavailable` means Verify was temporarily unavailable.

### How it works

This Actor is a thin wrapper around Sentinel Verify's `POST /v1/utilities/inspect-ai-crawler-policy` endpoint. Each domain is checked locally against API-IFY's public-network policy before being sent to Verify.

### Limitations

- Public HTTPS domains only; private, loopback, link-local, metadata, reserved, and CGNAT targets are rejected.
- Reports declared `robots.txt` policy, not observed crawler activity.
- Audit availability depends on Sentinel Verify.

### Privacy and security

The target domain is sent to Sentinel's live Utility API (`/v1/utilities/inspect-ai-crawler-policy`) for analysis after local public-network validation. Results are stored in the customer's Apify run dataset and summary store. `VERIFY_API_KEY` is an operator-managed Actor secret — a scoped `utilities:read` Intelligence API key sent as a bearer token on every request, the same credential mechanism used by any other Utility API consumer; `VERIFY_BASE_URL` is an operator setting, not an Actor input.

### Support

For a reproducible support request, provide the Apify run ID, result `itemId`, and status. Contact Sentinel Signal Systems through the support link on the Actor page.

# 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 example

```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 = {};

// Run the Actor and wait for it to finish
const run = await client.actor("bmiller1009/ai-crawler-access-checker").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();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("bmiller1009/ai-crawler-access-checker").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call bmiller1009/ai-crawler-access-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,bmiller1009/ai-crawler-access-checker"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
