Investment Growth API

How fast each economy's businesses and governments are investing in new capital, on one comparable screen — real gross fixed capital formation growth from the OECD's official Quarterly National Accounts as an API, live, no key. Gross fixed capital formation — investment in machinery, buildings, infrastructure and equipment — is the most cyclical and forward-looking component of GDP: firms only commit to new plant and projects when they are confident about demand, so investment turns down before recessions and surges first in recoveries. Its year-on-year change is one of the cleanest reads on the business cycle, and a swing factor that moves the currency and the capex-exposed parts of the equity market. The OECD harmonises and seasonally adjusts the real, chain-linked-volume figures so they are genuinely comparable across countries. This API serves the two growth rates people quote — quarter-on-quarter (the latest quarter's pace) and year-on-year (versus the same quarter a year earlier) — for real investment. The board endpoint ranks every economy by its year-on-year investment growth, so you can see where capex is booming and where it is collapsing. The momentum endpoint ranks by the latest quarter-on-quarter move. The country endpoint gives one economy's investment growth with a plain-language read. Each reading carries its own quarter and discontinued series are excluded, so the board is genuinely current. The capital-investment / capex cut — distinct from the headline GDP-growth board (this isolates the investment component), the consumer-demand and trade boards, the annual IMF World Economic Outlook database, and the generic multi-provider data aggregator. Figures are quarterly, in percent.

Investment Return API
Investment return analysis as an API, computed locally and deterministically. The cagr endpoint computes the compound annual growth rate, (end/begin)^(1/years) − 1 — the single constant yearly rate that turns a starting value into an ending value — along with the total return and growth multiple, or runs the other way to project an ending value from a CAGR. The doubling endpoint gives how long an investment takes to double at a given rate, both the exact figure ln(2)/ln(1+r) and the quick Rule-of-72, -70 and -69.3 estimates, or inverts it to the rate needed to double within a target time. The real-return endpoint applies the Fisher equation, real = (1+nominal)/(1+inflation) − 1, to strip inflation out of a headline return — or works backwards to the nominal return needed for a target real return — showing how the rough nominal-minus-inflation shortcut drifts at higher rates. Everything is computed locally and deterministically, so it is instant and private. Ideal for fintech, robo-advisor, portfolio and personal-finance app developers, return and retirement calculators, and finance education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This analyses a lump-sum return; for regular-deposit savings projections use a savings API and for loan amortization a loan API.

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.

Net International Investment Position API
The stock of external wealth — how much each economy owns abroad versus how much the rest of the world owns of it, live from the OECD's official balance-of-payments statistics, no key. Where the current account is the yearly flow of external lending or borrowing, the net international investment position (Net IIP) is the accumulated stock those flows pile up into: a country running persistent surpluses builds a large positive Net IIP and becomes a net creditor to the world (Norway, Japan, Germany, Switzerland), while persistent deficits build a large negative one — a net debtor, like the United States. The Net IIP is one of the deepest gauges of external sustainability and a structural anchor for a currency: a big positive position earns net income on foreign assets and is a buffer in a crisis, while a large negative one leaves a currency exposed to the willingness of foreigners to keep funding it. The board endpoint ranks economies by their Net IIP as a share of GDP — the size-neutral cross-country screen — from biggest net creditors to biggest net debtors. The gross endpoint ranks by gross external assets as a share of GDP, a measure of financial openness and international integration where small financial hubs tower with foreign assets worth multiples of GDP. The country endpoint gives one economy's full external balance sheet: the Net IIP in dollars and as a share of GDP, its gross foreign assets and liabilities, and the net position broken down by function — direct investment, portfolio investment, other investment and reserve assets, which sum to the net position — with a plain-language read. Each reading carries its own quarter and discontinued series are filtered out. This is the external-stock / net-foreign-wealth cut — the companion to, and distinct from, the current-account balance (the yearly flow, not the accumulated stock), trade growth, and the gross-government-debt and debt-service feeds (public-sector domestic debt, not the whole economy's external position). Positions are in billions of US dollars and percent of GDP; figures are quarterly end-of-period stocks.

Current Account Balance API
Whether each economy earns more from the rest of the world than it spends — the current-account balance, live from the OECD's official balance-of-payments statistics, no key. The current account is the single most important external-balance number in macro: it nets a country's trade in goods and services, its cross-border investment income, and its transfers into one figure. A surplus means the economy is a net lender to the world and is accumulating foreign claims; a deficit means it is a net borrower, financing its spending with foreign capital. Persistent current-account positions are one of the deepest drivers of exchange rates — surplus currencies (the yen, the euro-area core, the Nordics) tend to be structurally supported, while large-deficit currencies depend on continued capital inflows and are vulnerable when risk appetite turns. The board endpoint ranks economies by their current-account balance as a share of GDP — the size-neutral cross-country screen — from biggest surpluses to biggest deficits. The goods endpoint ranks by the merchandise (goods) trade balance as a share of GDP, separating the trade story from services and income. The country endpoint gives one economy's full external decomposition: the headline balance as a share of GDP, the goods / services / primary-income / secondary-income balances in US dollars (which sum exactly to the current account) and as shares of GDP, the six-quarter trend, and a plain-language read of whether the position is improving or deteriorating and what drives it. Each reading carries its own quarter and discontinued series are filtered out. This is the external-balance / balance-of-payments cut — distinct from trade growth (real export and import growth rates, the flow of volumes, not the net balance), and from the inflation, labour-cost and confidence feeds. The headline is percent of GDP; the decomposition is in billions of US dollars per quarter and percent of GDP; figures are quarterly, seasonally adjusted.
