Guide

Everything you need to make the first request.

The base URL is shown on the home page and at the start of each example. The dataset name with a .json extension is added to it.

The data is served as-is; on the client side it only needs to be parsed.

Do I need a token

No. The service neither requires nor checks a token, an authorization header or a cookie.

A request comes down to opening an address; everything else is the client's business.

A dataset address is a contract. While it lives, the response shape is predictable.

We announce the retirement of a version in advance on the documentation page.

The service answers with standard HTTP codes. A successful response comes with code 200 and a JSON body.

If a dataset or record is missing, you get 404. On too many requests, 429; try again later.

Each object in the array describes one record: a country, currency, zone or unit. The set of fields is the same for every record in a dataset.

We avoid empty and optional fields so parsing stays simple.

Code	Meaning
200	Request succeeded; the body is JSON.
404	No such dataset or record.
429	Too many requests, try again shortly.
