TIPS Real Yields & Breakeven Inflation API

healthy 4,750 Subscribers

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.

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.

Advice Slip API

Short pieces of advice via the open Advice Slip API — no key. The random endpoint returns a random advice slip; the advice endpoint fetches a specific slip by its id; and the search endpoint finds slips containing a phrase. Each slip carries its id and advice text. Real advice, with id lookups cached for speed — no key. 4 endpoints. Ideal for daily-advice widgets, chatbots, fortune-cookie features, loading screens and onboarding delight.

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.

Crypto Treasury API

Live data on the public companies that hold Bitcoin and Ethereum on their balance sheets, from the public CoinGecko feed. Rank every public company by how much of the coin it holds, with current and entry value, average entry price, country and share of total supply; get the aggregate corporate holdings, USD value and market-cap dominance; find a specific holder by name, ticker or country; and compare Bitcoin and Ethereum corporate treasuries side by side. The corporate crypto-treasury layer — distinct from price and exchange feeds: it answers who holds how much, and what they paid. Live, with a short 60-second upstream cache.
