Automated Accessibility Audits: The PageBolt /audit Endpoint

You just deployed a new feature. Everything looks great. But you forgot to test one thing: accessibility.

A week later, a customer reports: "Your new page is completely unusable with a screen reader." Another customer: "The color contrast is too low, I can't read it."

You scramble to fix it. Now you're patching live code. The feature could have shipped accessible if you'd just run an audit before release.

Here's the reality: 95% of websites fail accessibility checks. It's not because developers are careless. It's because accessibility testing isn't automated. It's manual, tedious, and easy to skip.

The Problem: Manual Accessibility Testing

Right now, your accessibility workflow probably looks like:

• Developer manually clicks through pages
• Browser extensions run axe, highlight violations
• Developer fixes them manually
• QA tests screen reader (if you have time)
• Edge cases slip through

It's slow. It's incomplete. Violations ship to production.

The Solution: /audit Endpoint

PageBolt's /audit endpoint runs axe-core (the industry standard) on any URL and returns violations organized by severity.

const response = await fetch('https://api.pagebolt.com/v1/audit', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer YOUR_API_KEY`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    url: 'https://yoursite.com/new-feature'
  })
});

const data = await response.json();
console.log(data.violations);
// Returns: [
//   { severity: 'critical', count: 2, violations: [...] },
//   { severity: 'serious', count: 5, violations: [...] },
//   { severity: 'minor', count: 12, violations: [...] }
// ]

One API call. Full accessibility audit. Violations sorted by severity.

Real Example: CI/CD Accessibility Gate

You want to enforce accessibility in your deployment pipeline. No feature ships without passing accessibility checks.

const axios = require('axios');

async function auditPageBeforeDeploy(stagingUrl) {
  console.log(`Running accessibility audit on ${stagingUrl}...`);

  const response = await fetch('https://api.pagebolt.com/v1/audit', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.PAGEBOLT_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      url: stagingUrl,
      standard: 'wcag2aa' // or wcag21aa, section508
    })
  });

  const audit = await response.json();

  // Check for critical violations
  const critical = audit.violations.find(v => v.severity === 'critical');

  if (critical && critical.count > 0) {
    console.error(`❌ DEPLOYMENT BLOCKED: ${critical.count} critical accessibility violations`);
    critical.violations.forEach(v => {
      console.error(`   - ${v.description}`);
      console.error(`     Impact: ${v.impact}`);
      console.error(`     Fix: ${v.remediation}`);
    });
    process.exit(1);
  }

  const serious = audit.violations.find(v => v.severity === 'serious');
  if (serious && serious.count > 0) {
    console.warn(`⚠️  Warning: ${serious.count} serious violations (review before shipping)`);
  }

  console.log(`✅ Accessibility check passed`);
  return true;
}

// In your GitHub Actions workflow
await auditPageBeforeDeploy(process.env.STAGING_URL);
// Runs as part of CI/CD. Fails the build if violations found.

What /audit Returns

{
  "url": "https://yoursite.com/page",
  "tested_at": "2026-03-18T14:32:00Z",
  "passes": 25,
  "violations": [
    {
      "severity": "critical",
      "count": 2,
      "violations": [
        {
          "id": "color-contrast",
          "description": "Background and foreground colors do not have sufficient contrast",
          "elements_affected": 3,
          "impact": "Users with low vision cannot read the text",
          "remediation": "Change text color to #000000 or background to #ffffff",
          "help_url": "https://dequeuniversity.com/rules/axe/..."
        }
      ]
    },
    {
      "severity": "serious",
      "count": 5,
      "violations": [...]
    }
  ]
}

Full details for every violation. Severity, element count, remediation guidance.

Use Cases

Deploy gate: Block deployments if critical violations detected

Compliance: Prove WCAG 2.1 AA compliance to auditors (screenshot + audit report)

Competitor monitoring: Audit competitor sites, compare accessibility maturity

Bulk auditing: Audit 100 pages weekly, track progress over time

Team accountability: Engineering dashboard showing accessibility violations by page

Customer demands: Enterprise customers often require accessibility certification

Cost vs. Manual Testing

Manual approach:

• Developer time: 30 min per page
• Coverage: ~70% of violations caught
• Cost: 5 pages/week × 0.5 hours × $150/hr = $375/week

/audit approach:

• API call: <1 second per page
• Coverage: ~95% of violations caught (axe-core standard)
• Cost: $29/month (Starter) = $1.50/audit if doing 500/month

Annual savings: $19,000+ if auditing 5 pages/week

Plus: automated audits catch issues before they ship. Manual testing catches them in production.
