US Reference Rates API
Live US money-market benchmark rates from the Federal Reserve Bank of New York's public markets API — no key, nothing cached. These are the rates that price trillions of dollars of loans and derivatives now that LIBOR is gone. The rates endpoint returns every benchmark the New York Fed publishes in one call: SOFR (the Secured Overnight Financing Rate, the headline US benchmark, around 3.6% on over three trillion dollars of daily volume), the Effective Federal Funds Rate (EFFR), the Overnight Bank Funding Rate (OBFR), and the Treasury and Broad General Collateral Rates (TGCR, BGCR) — each with its rate, the daily transaction volume in billions and the effective date. The sofr endpoint gives SOFR in detail with its full percentile distribution (1st, 25th, 75th, 99th) and recent trend. The history endpoint returns the recent daily path of any one rate. This is the benchmark-rate layer for any fixed-income, derivatives, lending, treasury or macro app that needs authoritative US overnight rates. Live from the New York Fed, nothing stored. Distinct from the ECB and central-bank-policy APIs — these are the US secured and unsecured money-market reference rates. 4 endpoints.
