How this service works
Pay-per-call tools for AI agents, 31 in all: read web pages and RSS feeds, OCR, PDF text, transcription; email, phone and domain checks; UK, Irish and Polish company lookups and UK risk reports; website contacts, tech stack and SEO audits; PageSpeed; AI review, job post and row enrichment; data cleaning, joins, dedupe and diffs; US and EU compliance rules. No account or API key: pay each call in USDC on Base over x402.
Output
A JSON object with a 'rows' array where each item contains the tested URL, final URL, check timestamp, redirect flag, duplicate flag, mobile/desktop status, Lighthouse version, scores (performance, accessibility, best-practices, SEO) with ratings (good/needs improvement/poor), Core Web Vitals (LCP, CLS, INP, TBT), a link to the full PageSpeed report, and up to N optimization opportunity descriptions with estimated savings — plus a summary count.
Example use cases
Pre-launch site performance audit
“Before we launch, can you run PageSpeed Insights on these 5 pages — https://mystore.com, https://mystore.com/products, https://mystore.com/checkout, https://mystore.com/about, and https://mystore.com/contact — on mobile, and show me the performance and SEO scores plus the top 3 things to fix on each page?”
Competitor benchmarking
“I want to compare my site against two competitors — run Lighthouse on https://mysite.com, https://competitor1.com, and https://competitor2.com for desktop strategy, return all four categories, and flag any pages scoring below 50 on performance.”
Accessibility compliance check
“Can you check these 8 pages for accessibility and best-practices scores using PageSpeed Insights on mobile? Here are the URLs: https://gov-portal.example.org/home, /services, /about, /contact, /faq, /apply, /results, /help — I only need the accessibility and best-practices categories, no performance or SEO.”
Technical details
Endpoint
POSThttps://x402-agent-tools.nerolabs.workers.dev/pagespeed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need bulk Lighthouse audits (up to 10 pages in one call) with structured JSON output including Core Web Vitals, category scores, and actionable fix suggestions — especially when you want to automate performance monitoring or integrate scores into a reporting pipeline. Prefer this over manually running PageSpeed.web.dev when you need machine-readable results across multiple pages at once.
Side effects
- URL is unreachable or returns non-200 status — row shows error status
- More than 10 URLs submitted — request rejected or truncated
- PageSpeed API timeout for slow or heavy pages — row may show error
- Invalid URL format — row flagged with error status
- Strategy enum value not recognized — validation error returned
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| urls | array | Optional. A plain list of pages to test, one per line (for example example.com or https://www.python.org/). Use this when you have no dataset, file or sheet. Combined with 'Data (inline)' if both are set. |
| strategy | string | Google tests the page as a mid-range phone on a slow connection, or as a computer. Google ranks on the mobile version, so most people want mobile. 'Both' runs two tests per page and adds mobile* and desktop* columns side by side. |
| categories | array | Which Lighthouse scores to return. The price is the same whichever you pick; leaving some out makes each test a little faster. |
| slowBelowScore | integer | Sets the 'Slow sites only' and 'Fast sites only' filters and the slow count in the summary. Google's own bands: 90 and up is good, 50 to 89 needs improvement, under 50 is poor. |
| maxOpportunities | integer | How many of Google's 'what would make this faster' suggestions to return per page, biggest estimated time saving first (for example 'Reduce unused JavaScript (Est savings of 588 KiB)'). 0 turns them off. |
