Sources
Every number here comes from a public publisher. Most arrive through the datasites APIs, a family of free, keyless APIs that each re-read one kind of public data, keep every version, and record the publisher's own files by checksum. This site reads 21 of their 29 datasets. Its checks then go back to the publisher's files and recompute every figure without the API.

What the checks read
The site's checks never trust the API a number came through. For each publisher they fetch the original files below, accept them only if their checksum is the one the API version recorded (or, for a file the publisher has revised since, say so and limit what may differ), and recompute every figure from them.
