What is moving across the bond market, by duration and credit, computed live from Yahoo Finance via the major fixed-income ETFs (no key, nothing stored). Bonds are the other half of every portfolio, and their moves are the cleanest read on interest rates and credit: when long Treasuries (TLT) fall, the market is pricing higher long rates; when high-yield (HYG) lags investment-grade (LQD), credit risk is being repriced. For every fixed-income ETF — Treasuries from ultra-short to 20-year-plus, investment-grade and high-yield credit, TIPS, munis, emerging-market and aggregate bonds — this measures the change on the day, the week and the month, the 52-week high and low and where the price sits in that range, tagged by category and rate sensitivity. The board endpoint returns the whole complex ranked by daily change with the gainers and losers and a category breakdown. The bond endpoint returns one ETF's performance card. The bonds endpoint lists what is covered. The fixed-income performance / bond-board cut — distinct from the government-bond-yield, yield-curve, central-bank-rate and bond-pricing-math APIs. Remember: a bond ETF's price moves inverse to its yield.

BYMA Argentina Stock Exchange API
Live data from BYMA (Bolsas y Mercados Argentinos), the Argentine exchange, with no key. Read the live value of every BYMA index — the S&P MERVAL, the S&P BYMA General and the BYMA CEDEAR index among them — with level, change and VWAP; look up a single index; pull the public-bond market with prices, maturities and days-to-maturity (Argentine sovereign and public bonds); and look up a single bond. The Argentina-equities-index / sovereign-bond layer for trading dashboards, screeners and research — distinct from other exchange readers, this is BYMA index and bond data. Live from the BYMA free API; short cache only.

MOEX Moscow Exchange API
Live multi-market data from the Moscow Exchange (MOEX), with no key. Read the live quote for any share (last, open/high/low, change, volume and value); the bond market with clean prices, yields to maturity and maturity dates (government OFZ and corporate); the value of any MOEX index (IMOEX, RTSI and the rest); the end-of-day price history; and the securities directory for shares, bonds or indices. The Russia-equities / bonds-with-yield / multi-market layer for trading dashboards, screeners and research — distinct from other exchange readers, MOEX spans shares, bonds and indices in one feed. Live from the MOEX ISS API; short cache only.

Cross-Asset Correlation Matrix API
How the major asset classes move together — a live correlation matrix across stocks, bonds, gold, oil, crypto and the dollar (no key, nothing stored). Correlation is the single most important input to diversification and risk: two assets with a correlation near 1 are effectively the same bet, while a low or negative correlation is genuine diversification. Where a crypto-correlation API stays inside crypto and an FX-correlation API stays inside currencies, this spans the whole multi-asset book at once — US and international equities, Treasuries and credit, gold, silver, oil and broad commodities, Bitcoin and Ether, the dollar and real estate — so an allocator can see in one call whether bonds are still hedging stocks, whether gold is decoupled and whether crypto is trading as a risk asset. The matrix endpoint returns the full pairwise return-correlation matrix over a chosen window, with the most- and least-correlated pairs. The asset endpoint returns one asset's correlation to every other, ranked, so you see its best diversifiers at a glance. The assets endpoint lists what is covered. The cross-asset / multi-asset correlation surface — distinct from the crypto-only correlation API, the FX-only currency-correlation API and the bring-your-own-series CAPM, risk-metrics and portfolio-optimiser calculators.

US Treasury Auctions API
Live results and schedule of US Treasury debt auctions, served from the US Treasury's FiscalData API — no key, nothing cached. Every Treasury bill, note, bond, TIPS and FRN is sold at auction, and the results are the market's clearest read on demand for US government debt. The auctions endpoint returns the most recent auctions — bills, notes, bonds and more — each with its CUSIP, security type and term, auction and issue dates and offering amount. The results endpoint returns the recently completed auctions with the numbers that matter: the high yield or discount rate, the bid-to-cover ratio (how many dollars were bid for each dollar offered — the headline demand gauge, around 2.5 for a healthy 20-year bond), the interest rate and the price. The security endpoint returns the full detail of one auctioned security by its CUSIP. Everything is the Treasury's own published auction data, live, nothing stored. This is the Treasury-auction layer for any fixed-income, rates, macro or research app. Distinct from debt-level and yield-curve APIs — this is the auction calendar and results: what the Treasury sold, at what yield, and how strong the demand was. 3 endpoints, no key on our side.
