## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

## LLMs.txt Discovery Auditor

Audit a website for `/llms.txt` and `/llms-full.txt` AI discovery readiness. Returns a readiness score, markdown structure summary, and actionable recommendations. The `llms.txt` convention lets websites expose clean markdown for AI crawlers and LLMs.

### Use cases

- **GEO/AI-SEO consultants** - audit client sites for AI crawler readiness
- **Documentation teams** - verify `/llms.txt` is properly structured and linked
- **B2B SaaS marketers** - ensure product docs are discoverable by AI search
- **DevRel teams** - check that documentation is AI-accessible
- **AI search consultants** - benchmark competitor AI discovery readiness

### Input

| Field | Type | Required | Default | Description |
|---|---|---|---|---|
| `startUrl` | string | yes | - | Public website URL to audit |
| `checkFullFile` | boolean | no | `true` | Also check `/llms-full.txt` |
| `timeoutSeconds` | integer | no | `10` | Per-request timeout (3-30 seconds) |

#### Example input

```json
{
  "startUrl": "https://example.com",
  "checkFullFile": true,
  "timeoutSeconds": 10
}
````

### Output

A single dataset item with the full audit:

| `checkedAt` | string | ISO timestamp |
| `files` | array | Per-file audit results (see below) |
| `recommendations` | array | Actionable recommendations |

#### `files` array

Each entry contains:

| Field | Type | Description |

| `path` | string | File path checked (`/llms.txt` or `/llms-full.txt`) |
| `present` | boolean | Whether the file exists and has content |
| `status` | integer | HTTP status code |
| `finalUrl` | string | Final URL after redirects |
| `contentType` | string | HTTP content-type |
| `byteLength` | integer | File size in bytes |
| `truncated` | boolean | Whether the file exceeded the 1 MB limit |
| `title` | string | H1 title extracted from the markdown |
| `headingCount` | integer | Number of headings in the file |
| `headings` | array | First 20 headings with level and text |
| `linkCount` | integer | Number of markdown links |
| `links` | array | First 100 links with text, URL, and domain |
| `uniqueLinkedDomains` | array | Unique domains linked from the file |
| `likelyDocsLinks` | array | Links matching docs/api/guide/reference patterns |
| `lineCount` | integer | Total line count |
| `warnings` | array | Issues found (missing file, empty, HTML instead of markdown, no links, etc.) |

#### Score breakdown

| Condition | Points |
|---|---|
| `/llms.txt` present | +45 (baseline) |
| H1 title present | +10 |
| 2+ headings | +10 |
| 5+ links | +15 |
| 2+ documentation links | +10 |
| `/llms-full.txt` present | +10 |
| **Maximum** | **100** |

### FAQ

**What is llms.txt?**
`llms.txt` is a convention where websites expose a markdown file at `/llms.txt` to help AI crawlers and LLMs understand their content. It serves a similar role to `robots.txt` but for AI models.

**What is the difference between /llms.txt and /llms-full.txt?**
`/llms.txt` is a concise overview with curated links. `/llms-full.txt` is the complete documentation in markdown. The actor checks both by default.

**What does the readiness score mean?**
The score (0-100) is based on file presence, content quality (headings, links, title), and whether the response is markdown rather than HTML. Higher scores indicate better AI discovery readiness.

**Can I audit multiple sites in one run?**
This actor audits one site per run. For bulk audits, schedule multiple runs.

# Actor input Schema
