Reference data API
Every table on this site is also a file. Static JSON and CSV, no key, no rate limit, no sign up, CORS open to everything. Use it in a build step, a test fixture, or a side project.

One request lists everything, including the record count and the last change date of each dataset:
Then fetch the dataset you want:
Or the same data as CSV, for a spreadsheet:
Every JSON file is wrapped in an envelope that says where the data came from and how to credit it, so a consumer never has to guess:
The recordCount is counted from the array being served, so it can never disagree with the payload. The checkedAt field is null where the data has not been re-verified against its primary source; that is deliberate, and the methodology explains what it means.

The data is published under CC BY 4.0. You can copy it, change it, and use it commercially. In return, credit it: the line Data from quickref.tips with a link is enough. The full text, with a copy and paste attribution block, is on the licence page.
The files are static and cached for a day, so hammering them costs you nothing and costs us nothing. There is no key and there will not be one. If an endpoint is wrong, that is a bug worth reporting: see the methodology for how.
