SOFR Averages & Index API

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).

Funding Spreads & Repo Stress API
The money-market spreads that signal whether US dollar funding is calm or seizing up, computed live from the Federal Reserve Bank of New York's public rates API — no key, nothing stored. The headline overnight rates all sit within a few basis points of each other when markets are healthy; it is the spreads between them, and their spikes, that reveal stress. The most-watched is SOFR minus EFFR: SOFR is the cost of secured (collateralised, repo) borrowing and EFFR the cost of unsecured fed-funds borrowing, so when SOFR climbs above EFFR it means collateral is suddenly expensive — the classic repo-stress signal that blew out in September 2019 and around quarter-ends. This API computes that and the other key spreads — SOFR vs the Overnight Bank Funding Rate, SOFR vs the Broad General Collateral Rate, and the general-vs-tri-party collateral spread — in basis points, with a funding-stress regime read. The spreads endpoint returns the live rate board and every spread; the distribution endpoint returns SOFR's intraday percentile spread (99th minus 1st), a within-day dispersion gauge that widens when funding is segmented; the history endpoint returns the time series of any spread and counts the stress days. This is the funding-stress / money-market-spread cut — distinct from the raw NY-Fed rate-level feed (which lists the rates but not the spreads or the stress signal), the central-bank-policy and the yield-curve APIs. It is the gap between the rates, which is where the stress lives.

US Reference Rates API
Live US money-market benchmark rates from the Federal Reserve Bank of New York's public markets API — no key, nothing cached. These are the rates that price trillions of dollars of loans and derivatives now that LIBOR is gone. The rates endpoint returns every benchmark the New York Fed publishes in one call: SOFR (the Secured Overnight Financing Rate, the headline US benchmark, around 3.6% on over three trillion dollars of daily volume), the Effective Federal Funds Rate (EFFR), the Overnight Bank Funding Rate (OBFR), and the Treasury and Broad General Collateral Rates (TGCR, BGCR) — each with its rate, the daily transaction volume in billions and the effective date. The sofr endpoint gives SOFR in detail with its full percentile distribution (1st, 25th, 75th, 99th) and recent trend. The history endpoint returns the recent daily path of any one rate. This is the benchmark-rate layer for any fixed-income, derivatives, lending, treasury or macro app that needs authoritative US overnight rates. Live from the New York Fed, nothing stored. Distinct from the ECB and central-bank-policy APIs — these are the US secured and unsecured money-market reference rates. 4 endpoints.

OECD Economic Indicators API
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.

South African Reserve Bank (SARB) API
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. The fx endpoint isolates the rand exchange rates — rand per US dollar, British pound, euro and Japanese yen — plus the nominal effective exchange rate. The interest endpoint returns the policy and lending rates with the benchmark bond yields. The inflation endpoint returns the latest CPI and PPI. The marketrates endpoint returns the fuller current money-market rate list. Every indicator carries its own as-of date and a direction versus the prior print. 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.
