As of 2026-10-25 (UTC): 20 active currencies, with the 1-day delay of the free tier. A currency is active when the index has a day within the last 14 days. Rates are fiat per 1 USDT, so a rising index means the currency is weakening.
Sources — independent market sources behind the latest day (shown from two on). high / medium / limited — confidence class: limited means fewer sources or fewer data points, or a latest day that is a few days old. Updated — when the latest day of the currency was. Every code links to the currency page with charts, the last 30 days and the official-vs-street comparison where available. The API serves the full history of every currency (API reference).
Coverage in progress: 38 currencies
We are adding market sources for these currencies. A currency moves to the table above on its own once its index has a recent day; the history already published stays available in the API.
