Everything in one call, and the one most people want. Scores with their spread, real-user data if Google has any, and what is failing ranked by what fixing it is worth. Returns a self-contained HTML page as well, to save or forward. Comes back as a job id.

check_pagespeed

Scores only. Median of N distinct analyses with the spread. `urls`, `strategy` (mobile, desktop or both), `runs` (1-10, default 5). Anything past a single analysis comes back as a job id.

diagnose_page

What is failing, ranked. Only reports a fault that failed in every analysis, because audits are as noisy as scores. Comes back as a job id.

field_data

Real-user data from the Chrome UX Report. `urls`, and `history` for the weekly p75 series.

explain_lcp

Which of four phases owns a slow Largest Contentful Paint: server response, the wait before the browser starts fetching the largest image, the download, then the wait before it is painted. One call, answers at once.
