## 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

## Robots.txt Auditor

Parse supplied robots.txt content into user-agent-scoped directives and flag site-wide crawl blocks.

### Inputs

- `domains`
- `maxDirectives`
- `includeReport`
- `maxChargeUsd`

```json
{
  "domains": [
    {
      "domain": "www.iana.org",
      "statusCode": 200,
      "robotsTxt": "User-agent: *\nDisallow:"
    }
  ],
  "maxDirectives": 2,
  "includeReport": true,
  "maxChargeUsd": 1
}
```

The bundled exact input is a public observation of `https://www.iana.org/robots.txt` captured at 2026-07-12T05:03:20Z; the actor analyzes the supplied snapshot and does not refetch it.

### Dataset

The actor emits structured, actor-specific evidence rows. Empty source input, or a comparison with no selected changes, produces no dataset rows.

### Billing

This actor uses pay-per-event billing with platform usage included in the configured event prices. Configured events are:

- `actor-start`
- `robots-file-checked`
- `rule-parsed`
- `finding-emitted`
- `audit-report-generated`

Every dataset row and report artifact is charge-gated. A zero-dollar cap stops before work with no paid output.

### Use Cases

- Find a site-wide robots.txt block
- Review Googlebot-specific directives
- Export a robots.txt sitemap directive
- Audit multiple robots user agents
- Verify an explicit robots.txt allow rule

### Limitations

The actor analyzes supplied robots.txt observations and does not fetch URLs. It parses User-agent, Allow, Disallow, and Sitemap directives; unsupported extensions remain outside the dataset.

# Actor input Schema

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

Domains and observed robots.txt content.

## `maxDirectives` (type: `integer`):

Hard cap for paid directive rows.

## `includeReport` (type: `boolean`):

Create charged Markdown and JSON report artifacts.

## `maxChargeUsd` (type: `number`):

Stop before an event would exceed this run budget.

## Actor input object example

```json
{
  "domains": [
    {
      "domain": "www.iana.org",
      "statusCode": 200,
      "robotsTxt": "User-agent: *\nDisallow:"
    }
  ],
  "maxDirectives": 2,
  "includeReport": true,
  "maxChargeUsd": 1
}
```

# Actor output Schema

## `dataset` (type: `string`):

Structured rows emitted by the actor.

## `report` (type: `string`):

Run summary report stored in the default key-value store.

# 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("junipr/robots-txt-auditor").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("junipr/robots-txt-auditor").call(run_input=run_input)

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