PageSpeed Insights API
Analyze a page with runPagespeed and feed performance diagnostics into site quality tooling.
Simple surface centered on runPagespeed
Very narrow surface, not a general website management API
Start with a single runPagespeed request against a target URL, then decide how you want to store thresholds, regressions, and historical comparisons in your build pipeline.

About this API
This API is intentionally narrow: the center of gravity is runPagespeed. Its value comes from turning page performance analysis into an automated check, release gate, or trend dashboard. In the published OpenAPI surface, the most concrete handles are "/pagespeedonline/v5/runPagespeed", backed by tags such as "pagespeedapi".
That makes the API practical for run page performance checks in ci, track regression on important urls, and pipe optimization suggestions into a site quality dashboard. The spec lists scopes such as "openid".
