Vietnam Exchange Rates API

healthy 3,724 Subscribers

Live Vietnamese đồng (VND) bank counter exchange rates from Vietcombank, Vietnam's largest commercial bank. Unlike a central-bank reference or a parallel-market rate, these are the rates a customer actually transacts at, quoted in three forms: the cash rate (buying banknotes), the transfer rate (buying via wire) and the sell rate (the bank selling foreign currency). The rates endpoint returns every quoted currency against the đồng with all three rates and the buy/sell spread; the rate endpoint returns one currency; the convert endpoint converts any amount between a currency and the đồng at the chosen rate. Read live, nothing stored. This is Vietnam's own commercial-bank counter-rate layer — distinct from central-bank reference feeds and from parallel-market APIs.

US Debt Composition API

What the US national debt is actually made of, served from the Treasury's Monthly Statement of the Public Debt. The headline debt-to-the-penny figure is one number; this is the breakdown — how the roughly $39 trillion splits across Treasury Bills, Notes, Bonds, TIPS and Floating-Rate Notes (the marketable, tradable debt) versus the non-marketable debt (the Government Account Series held by federal trust funds, Savings Bonds, and State and Local Government Series). The composition endpoint returns the latest full breakdown by security class, each with its share of the total and its split between debt held by the public and intragovernmental holdings. The marketable endpoint isolates the tradable securities (Bills/Notes/Bonds/TIPS/FRN) with each one's share of marketable debt — the issuance mix that rates traders and the Treasury's quarterly refunding watch. The history endpoint returns one security class's outstanding amount month by month. This is the debt-structure data-cut, distinct from the debt-to-the-penny total, the fiscal-deficit and the yield-curve APIs in the catalogue. Live, updated monthly, no key on the upstream, nothing stored.

US Treasury Cash (TGA) API

The US federal government's checking account — the Treasury General Account (TGA) at the Federal Reserve — served from the official Daily Treasury Statement. The TGA is where the government's cash sits, and its day-to-day balance is a closely watched market-liquidity gauge: a falling TGA injects cash into the financial system, a rising one drains it. The balance endpoint returns the latest day's opening balance, total deposits, total withdrawals, closing balance and the net change, in millions and billions of dollars. The history endpoint returns the daily closing TGA balance over a window. The flows endpoint returns the latest day's largest cash deposits and withdrawals by category — withheld and corporate taxes coming in, Social Security and debt redemptions going out — so you can see exactly where the money moved. This is the Treasury-cash and fiscal-liquidity data-cut, distinct from the national-debt, fiscal-deficit and yield-curve APIs in the catalogue. Live, updated each business day, no key on the upstream, nothing stored.

TIPS Real Yields & Breakeven Inflation API

The inflation-adjusted side of the US Treasury yield curve, served from the Treasury's official daily feeds. The realyields endpoint returns the latest TIPS real yield curve — the inflation-protected (real) yield at the 5, 7, 10, 20 and 30-year maturities. The breakeven endpoint returns market-implied inflation: at each maturity it takes the nominal Treasury yield minus the real yield, which is the average annual inflation rate the bond market is pricing in over that horizon, and returns it alongside the nominal and real components. The history endpoint returns the daily time series of the real yield, the nominal yield and the breakeven inflation rate for one maturity over a year. A 10-year breakeven of 2.3 means the market is pricing roughly 2.3% average inflation over the next decade — a core gauge for rates traders, macro funds and inflation hedgers. This is the real-yield and inflation-expectations data-cut — distinct from the nominal yield-curve, the world-government-bond and the central-bank-rate APIs in the catalogue. Live, no key on the upstream, nothing stored.

Big Mac Index API

The Economist's Big Mac Index — "burgernomics" — as an API: how over- or under-valued the world's currencies are, measured by the price of a Big Mac. The same burger costing different amounts across countries reveals purchasing-power-parity (PPP) misalignment in exchange rates. The index endpoint returns the latest release for every country — the local Big Mac price, its US-dollar price at the market exchange rate, and the raw and GDP-adjusted over/under-valuation of that currency against a chosen base (USD, EUR, GBP, JPY or CNY). The country endpoint returns one country's full history — the valuation trend over every release since 2000. The extremes endpoint returns the most over-valued and most under-valued currencies in the latest release. A positive valuation means the currency is over-valued versus the base; negative means under-valued; the GDP-adjusted figure corrects for cheaper labour in poorer countries. This is a PPP / currency-valuation data-cut — a fundamental gauge, not a live FX tick — distinct from the spot-rate, central-bank and conversion APIs in the catalogue. Live from the open dataset, no key on the upstream, nothing stored.
