## How it works

The API is a set of JSON files generated every time the site is built, so it is always in step with the site. There are no keys, no accounts and no rate limits, and nothing is logged beyond what the static host keeps.

## Why an API

Most giving decisions happen somewhere else: on donation platforms, in workplace giving portals and in advisors’ spreadsheets. An open API lets the method travel to where decisions are made, which helps the system coordinate instead of fragmenting further. See [the Fragmentation Problem](/diagnosis/fragmentation/).
