Generating real reports since April 2026 · api.grevlo.com/docs

What you get

PageSpeed Score

Mobile and desktop Core Web Vitals from a live Lighthouse audit

SSL Certificate

Certificate validity, expiry date and issuer

Uptime Log

30-day availability record from real monitoring

Your retainer clients deserve better than a spreadsheet.

Web agencies spend 3 to 4 hours every month manually pulling uptime logs, running PageSpeed audits, and checking SSL certificates. The tools that exist were built for marketing agencies tracking ad spend, not developers proving infrastructure value.

You are either paying per-client fees for a dashboard your clients never log into, or spending Sunday afternoon copying numbers into a Word document.

Legacy reporting tools charge per client. Every agency win costs you more in software fees. That's a variable tax on your growth.

The old way

  • Manually pulling uptime logs
  • Paying per-client fees for dashboards clients ignore
  • Spending Sunday compiling spreadsheets
  • Data scattered across 5 different tools

The Grevlo way

  • One API call generates the full report
  • from £49/month, flat-rate pricing
  • Branded PDF delivered automatically
  • PageSpeed, SSL and uptime in one place

Three steps. One API call. One professional PDF.

01

Set up once

Upload your agency branding and connect your UptimeRobot account. Takes five minutes.

02

Point us at a URL

At the end of each month, POST your client's website URL to the Grevlo API. That is it.

03

Receive a branded PDF

Grevlo fetches live PageSpeed scores from Google, checks the SSL certificate, pulls uptime data from UptimeRobot, and returns a fully branded PDF report ready to send to your client. No dashboard. No login. No manual work.
