Bond / Fixed-Income Performance API
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.
