Data and API
The public API returns exactly the numbers on these pages, with 1000 requests a month on the free plan (data as of 2026-09-25, source: this page). MeasuredLab measures promise against fact: the file and the page are built from one slice.
Data as of 25 September 2026 · source: this page
How to read the data
Every page has an index.json next to it at the same address, and tables also have a .csv. The JSON is the very slice the page was built from, so a number in the file and the number on the page cannot drift apart. Exports carry an X-Robots-Tag: noindex header — they are for machines to read, not for search engines to index instead of the page.
Rules of use
Attribution to the source page is required. Quotes from third-party sources stay under their own rights: what we license is the measurement, not the material we measured. A name removed at its owner's request disappears from the exports too, on the same deadline as from the pages.

A plan marked “not switched on” cannot be bought yet — it is published so that the terms are known before it can be.
