Live US federal fiscal data from the US Treasury's official FiscalData API — the cost-and-flow side of US public finance. Get the federal budget deficit or surplus by month for the current fiscal year (receipts, outlays and the net) from the Monthly Treasury Statement; the interest the United States pays to service its national debt, by month and fiscal-year-to-date, broken down by security type; and the average interest rate the Treasury pays on each class of its debt (Bills, Notes, Bonds, TIPS) plus the weighted overall rate. Live, no key, nothing cached. Distinct from debt-level (debt-to-the-penny) and auction feeds — this is the deficit, the interest bill and the average rate on the debt.

Live Chilean economic indicators from mindicador.cl (Banco Central de Chile data). Chile runs on indicators no other currency uses: the UF (Unidad de Fomento) is an inflation-indexed unit that prices mortgages, rents and contracts, and the UTM (Unidad Tributaria Mensual) is the tax unit — both quoted in pesos and updated daily.

The indicators endpoint returns every indicator's latest value; the indicator endpoint returns one with its recent series; the history endpoint returns a full year of daily values; the convert endpoint converts amounts between the peso, UF, UTM, dollar and euro.

On P2P, people buy and sell USDT (a USD proxy) directly for local currency, so the advertised prices reveal the REAL street value of a currency — for stressed currencies (Argentine peso, Venezuelan bolívar, Nigerian naira and more) this is the rate the economy actually transacts at, far from the official one. The rate endpoint returns the best buy and sell P2P price for an asset in a fiat, the mid and the spread.

Live European wholesale (day-ahead) electricity prices and the live power-generation mix, from the Fraunhofer ISE Energy-Charts public data.

Turkey's high-inflation economy makes physical gold a primary store of value, and the gram-altın and coin prices quoted here are what the bazaar trades on.
