# MacroTape

> Daily treasuries, FX and crypto in one token-light brief, built for AI agents. Twice each U.S. weekday (AM ~7 AM ET, PM ~1 PM ET): U.S. Treasury par curve and spreads, USD FX crosses from ECB reference rates, and crypto market data. JSON and compact text. API key required (instant self-serve key, early access, payment comes later). Not investment advice.

Data comes straight from the U.S. Treasury, the ECB (via Frankfurter) and CoinGecko; numbers are never modeled or invented. If a core source fails, the run is skipped and the previous brief stays live. Treasuries cover every published par tenor (1M-30Y) with bp moves, spreads (2s10s, 3m10y, 2s5s, 5s30s, 10s30s) and a curve-shape label. FX covers every ECB currency vs USD with top movers and dollar breadth. Crypto covers BTC/ETH/SOL, total market cap, BTC/ETH dominance, top 20, altcoin gainers/losers (ex-stablecoins) and stablecoin market cap.
