PageSpeed + Accessibility Audit

Real Lighthouse scores for any website, in bulk. Feed a list of URLs, get back Performance and Accessibility scores, Core Web Vitals, and a ranked list of failing accessibility issues. One row per URL. Backed by Google's official PageSpeed Insights API.

What It Does

For every input URL the actor makes one call to Google's PageSpeed Insights (PSI) API v5 and extracts:

• Lighthouse Performance score (0-100)
• Lighthouse Accessibility score (0-100)
• Core Web Vitals: LCP, CLS, FCP, TBT, Speed Index, Time to Interactive, TTFB, plus INP (Interaction to Next Paint) from CrUX field data
• Accessibility issues: up to 20 failing audits, sorted by impact, with the specific WCAG rule and the count of failing elements per page
• Flags: good / needs_improvement / poor buckets matching Lighthouse's own thresholds

One PSI call returns both Performance and Accessibility, so you pay for one round-trip and get both signals. Best Practices and SEO categories are available via the includeExtraCategories toggle.

How to get your Google API key (3 minutes)

Bring your own key. Google offers a generous free tier of 25,000 queries per day per Google Cloud project with no credit card required.

1. Sign in at console.cloud.google.com and pick or create a project (skip the billing prompt when it appears — PSI is free).
2. Open the API Library, search for "PageSpeed Insights API", and click Enable.
3. Open Credentials, click Create Credentials → API key, copy the generated value.
4. Recommended: click the new key → Edit API key → Restrict key. Under API restrictions, select Restrict key and check only PageSpeed Insights API. This makes a leaked key useless for paid Google APIs.
5. Paste the key into the actor's googleApiKey input field.

The actor will refuse to start without a key and won't consume any billing events until you supply one.

Two shapes accepted, mix them freely.

Flat URL list:

{

  "googleApiKey": "AIza...",
  "strategy": "mobile"
}

Companies shape (with company_id passthrough for CRM join-back):

{
  "companies": [
    { "company_id": "acme-42", "website_url": "https://example-company.example" }
  ],
  "googleApiKey": "AIza..."
}

Configuration

Field	Default	Description
googleApiKey	(required)	Your Google Cloud API key with PageSpeed Insights API enabled
strategy	mobile	mobile or desktop Lighthouse profile
includeExtraCategories	false	Also return Best Practices + SEO scores
outputLanguage	en	ISO 639-1 code for issue titles (en, de, fr, es, ja, ...)
maxConcurrency	5	Parallel PSI calls in flight (max 10)

Output

One row per input URL:

{
  "company_id": "acme-42",
  "url": "https://example-company.example/",
  "final_url": "https://example-company.example/",
  "strategy": "mobile",
  "fetch_time": "2026-07-18T13:00:00.000Z",
  "scores": {
    "performance": 87,
    "accessibility": 92,
    "best_practices": null,
    "seo": null
  },
  "core_web_vitals": {
    "lcp_ms": 2100, "lcp_score": 0.85,
    "inp_ms": 162, "inp_flag": "good",
    "cls": 0.08, "cls_score": 0.92,
    "fcp_ms": 1800, "fcp_score": 0.88,
    "ttfb_ms": 640, "tbt_ms": 210, "si_ms": 3200, "tti_ms": 4100
  },
  "accessibility_issues": [
    {"id": "color-contrast", "title": "Background and foreground colors do not have a sufficient contrast ratio.", "impact": "serious", "count": 3},
    {"id": "image-alt", "title": "Image elements do not have [alt] attributes.", "impact": "critical", "count": 1}
  ],
  "flags": {
    "performance_flag": "good",
    "accessibility_flag": "needs_improvement"
  },
  "psi_status": "success",
  "scraped_at": "2026-07-18T13:00:05Z"
}

Failed audits still emit a row with psi_status: "failed" and psi_error populated, so N URLs in always equals N rows out.
