## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Accessibility WCAG / EAA Checker

Run [axe-core](https://github.com/dequelabs/axe-core) accessibility checks on public pages in bulk.

Default rule tags: **wcag2a, wcag2aa, wcag21a, wcag21aa, wcag22aa** — useful for **EAA readiness reviews** that commonly reference WCAG 2.1 AA / EN 301 549.

**Not a legal compliance certificate.** Automated findings support remediation; they do not certify WCAG or EAA conformance.

Built by [Steadfeed](https://apify.com/steadfeed).

### How it works

1. Fetches each public URL as static HTML (polite, SSRF-safe)
2. Loads HTML into **jsdom** and runs **axe-core**
3. Returns violations (capped list), incomplete checks, pass sample, impact counts, and a 0–100 heuristic score

### Input

| Field | Default | Notes |
|---|---|---|
| `urls` | required | 1–40 public http(s) pages |
| `tags` | WCAG A/AA set above | axe-core tags |
| `includeBestPractice` | false | Adds axe `best-practice` rules |
| `maxViolationsListed` | 25 | Row size cap; counts still full |
| `dryRun` | false | Built-in fixture with known issues |

### Pricing (draft — not live until owner approval)

- **page-checked** — **$0.005** per successful page (`status=ok`)
- **Actor start** — $0.00005
- Error rows free; do not enable `apify-default-dataset-item`

### Limitations (honest)

- Static HTML / jsdom — **JS-rendered** content may be missed
- Some contrast, focus, and keyboard rules need a **real browser** and human testing
- Incomplete axe results mean “needs review,” not pass/fail
- jsdom may log missing canvas/`getContext` notices; they do not fail the run
- EAA coverage involves more than page HTML (docs, support, products); this Actor checks pages only

### Example

```json
{
  "urls": ["https://example.com/", "https://www.w3.org/WAI/"],
  "tags": ["wcag2a", "wcag2aa", "wcag21a", "wcag21aa", "wcag22aa"]
}
```

# Actor input Schema

## `urls` (type: `array`):

1–40 public http(s) page URLs. Static HTML is fetched and analyzed with axe-core in jsdom (no login, no full browser).

## `tags` (type: `array`):

Rule tags to run. Default: wcag2a, wcag2aa, wcag21a, wcag21aa, wcag22aa (AA-oriented, useful for EAA readiness reviews).

## `includeBestPractice` (type: `boolean`):

When true, also run axe best-practice rules (not strictly WCAG). Default false.

## `maxViolationsListed` (type: `integer`):

Cap on violation objects in the dataset row (5–100). Counts still reflect the full run. Default 25.

## `requestIntervalMs` (type: `integer`):

Polite per-host spacing. 200–30000; default 1000.

## `maxRetries` (type: `integer`):

Retries for network errors and 408/429/5xx. 0–5; default 2.

## `timeoutMs` (type: `integer`):

3000–60000; default 20000.

## `dryRun` (type: `boolean`):

When true, analyze a built-in fixture with known issues; no network. Default false.

## Actor input object example

  "urls": [
    "https://example.com/",
    "https://www.w3.org/WAI/"

    "wcag2aa",
    "wcag21a",

  ],
  "includeBestPractice": false,
  "maxViolationsListed": 25,
  "requestIntervalMs": 1000,
  "maxRetries": 2,
  "timeoutMs": 20000,
  "dryRun": false
}

# 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 = {
    "urls": [
        "https://example.com/",
        "https://www.w3.org/WAI/"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("steadfeed/accessibility-wcag-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 = { "urls": [
        "https://example.com/",
        "https://www.w3.org/WAI/",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("steadfeed/accessibility-wcag-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 '{
  "urls": [
    "https://example.com/",
    "https://www.w3.org/WAI/"
  ]
}' |
apify call steadfeed/accessibility-wcag-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,steadfeed/accessibility-wcag-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).
