Key macroeconomic indicators for the 38 OECD member countries, sourced from the official OECD SDMX data service. Pull the harmonised unemployment rate, the consumer price index and the long-term (10-year government bond) interest rate for any member country, look up a single indicator for one country, or read a full country snapshot with all indicators at once. Every value carries the indicator label, its unit and the exact period it refers to, and always resolves to the latest published observation — no date juggling. Coverage spans Australia to the United States, with the United Kingdom, Germany, Japan, France and every other OECD member in between. Built for dashboards, macro research and currency or rates models that need authoritative, comparable cross-country economic data. Distinct from market and FX feeds: this surfaces official OECD statistics.

The SOFR term reference rates that actually price US dollar floating-rate loans and notes, live from the Federal Reserve Bank of New York's public markets API — no key, nothing stored. Now that LIBOR is gone, trillions of dollars of loans, FRNs and derivatives reference SOFR, but almost none of them reference the overnight SOFR fixing directly: they reference the New York Fed's compounded SOFR Averages (30-, 90- and 180-day) and the SOFR Index, the backward-looking term rates that turn the daily fixing into a usable loan rate. The rates endpoint returns the three averages, the SOFR Index value and a plain-language read of the term-average slope (with the overnight SOFR for context). The accrual endpoint is the operational one: give it a start and end date and it computes the realized compounded SOFR over that period straight from the SOFR Index — the exact arithmetic (Index_end / Index_start − 1, ACT/360) a loan servicer or FRN desk runs to settle an interest period, with the resulting rate and dollar interest. The history endpoint returns the averages and index as a daily time series. This is the SOFR term-rate / accrual cut — distinct from the overnight money-market benchmark board (the daily SOFR fixing, without the compounded averages or the index) and from the funding-spread stress monitor (the spreads between overnight rates, not the term reference rates).

Live headline economic and financial indicators from the South African Reserve Bank (SARB), the central bank of South Africa — read straight from the SARB public web-indicators feed, no key, nothing stored. The dashboard endpoint returns the bank's full headline board exactly as published on its home page: the policy repo rate, prime lending rate, Sabor and Zaronia money-market rates, benchmark government-bond closing yields, the rand exchange rates and the latest inflation prints.

This is South-African central-bank data (ZAR rates, yields and inflation) — distinct from the crypto ZAR exchange-ticker and the other central-bank APIs in the catalogue.
