WCAG Accessibility Checker API | ADA & EAA Compliance Audit

Audit websites for WCAG 2.1 accessibility compliance in bulk. Get A-F grades, violation details with severity, and actionable remediation steps per URL.

Store Quickstart

Run this actor with your target input. Results appear in the Apify Dataset and can be piped to webhooks for real-time delivery. Use dryRun to validate before committing to a schedule.

Key Features

• 🛡️ Compliance-first — Produces audit-ready reports mapping findings to standards (WCAG, GDPR, SOC2)
• 🔒 Non-invasive scanning — Uses only observable public signals — no intrusive probing
• 📊 Severity-scored output — Each finding rated for criticality with remediation guidance
• 📡 Delta-alerting — Flag new findings since last run via webhook delivery
• 📋 Evidence export — Raw headers/responses captured for compliance documentation

Use Cases

Who	Why
Developers	Automate recurring data fetches without building custom scrapers
Data teams	Pipe structured output into analytics warehouses
Ops teams	Monitor changes via webhook alerts
Product managers	Track competitor/market signals without engineering time

Input

Field	Type	Default	Description
urls	array	prefilled	List of URLs to audit for WCAG accessibility compliance. Maximum 50 per run.
wcagLevel	string	"AA"	WCAG conformance level to check against. AA is the most common legal requirement (ADA, EAA). AAA is the strictest.
includeWarnings	boolean	true	Include incomplete checks that need manual review, in addition to definite violations.
delivery	string	"dataset"	How to deliver results. 'dataset' saves to Apify Dataset, 'webhook' sends to a URL.
webhookUrl	string	—	Webhook URL to send results to (only used when delivery is 'webhook'). Works with Slack, Discord, or any HTTP endpoint.
snapshotKey	string	"wcag-accessibility-snapshots"	Key name for storing snapshots (used for change detection between runs).
concurrency	integer	2	Parallel browser tabs. Higher = faster but uses more memory. Keep at 2-3 for most cases.
waitForSelector	string	—	Optional CSS selector to wait for before auditing. Useful for SPAs that load content dynamically.

Input Example

Output

Field	Type	Description
url	string (url)	Audited page URL
score	object	Overall score { total, grade (A-F), level (AA/AAA) }
summary	object	{ violations, critical, serious, moderate, minor, passes, incomplete, totalAffectedNodes }
violations	array	Array of WCAG violations with rule id, impact, description, nodes
recommendedActions	array	Prioritized remediation suggestions
changes	array	Diff vs previous snapshot (grade/total delta)

Output Example

{
  "status": "ok",

API Usage

Run this actor programmatically using the Apify API. Replace YOUR_API_TOKEN with your token from Apify Console → Settings → Integrations.

cURL

curl -X POST "https://api.apify.com/v2/acts/taroyamada~wcag-accessibility-checker/run-sync-get-dataset-items?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "urls": [ "https://example.com", "https://www.w3.org" ], "wcagLevel": "AA", "includeWarnings": true, "delivery": "dataset", "snapshotKey": "wcag-accessibility-snapshots", "concurrency": 2, "timeout": 30000, "dryRun": false }'

Python

from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("taroyamada/wcag-accessibility-checker").call(run_input={
  "urls": [
    "https://example.com",
    "https://www.w3.org"
  ],
  "wcagLevel": "AA",
  "includeWarnings": true,
  "delivery": "dataset",
  "snapshotKey": "wcag-accessibility-snapshots",
  "concurrency": 2,
  "timeout": 30000,
  "dryRun": false
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript / Node.js

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });
const run = await client.actor('taroyamada/wcag-accessibility-checker').call({
  "urls": [
    "https://example.com",
    "https://www.w3.org"
  ],
  "wcagLevel": "AA",
  "includeWarnings": true,
  "delivery": "dataset",
  "snapshotKey": "wcag-accessibility-snapshots",
  "concurrency": 2,
  "timeout": 30000,
  "dryRun": false
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

Tips & Limitations

• Schedule weekly runs against your production domains to catch config drift.
• Use webhook delivery to pipe findings into your SIEM (Splunk, Datadog, Elastic).
• For CI integration, block releases on critical severity findings using exit codes.
• Combine with ssl-certificate-monitor for layered cert + headers coverage.
• Findings include links to official remediation docs — share with dev teams via the webhook payload.

FAQ

Is running this against a third-party site legal?

Passive public-header scanning is generally permitted, but follow your own compliance policies. Only scan sites you have authorization for.

How often should I scan?

Weekly for production domains; daily if you have high config-change velocity.

Can I export to a compliance tool?

Use webhook delivery or Dataset API — formats map well to Drata, Vanta, OneTrust import templates.

Is this a penetration test?

No — this actor performs passive compliance scanning only. No exploitation, fuzzing, or auth bypass.

Does this qualify as a SOC2 control?

This actor produces evidence artifacts suitable for SOC2 CC7.1 (continuous monitoring). It is not itself a SOC2 certification.
