#reference-rates

The value of one bitcoin expressed across every unit CoinGecko tracks — world fiat currencies, precious metals (gold and silver, troy ounce) and other cryptocurrencies, powered by the public CoinGecko exchange-rates feed, no key, nothing stored. This is the "Bitcoin standard" / unit-of-account view: not a coin's dollar price, but how much of each asset one BTC buys right now — 1 BTC in US dollars, euros and yen, in ounces of gold and silver, and in ether, satoshi and dozens more. The rates endpoint returns every unit with its value and asset type; the rate endpoint returns one specific unit (gold, the euro, ether); the groups endpoint splits the units into fiat, commodity and crypto so you can see what a bitcoin is worth across asset classes at a glance. This is the Bitcoin-denominated reference-index cut — distinct from the coin-price converters, the market-overview and the per-exchange ticker APIs in the catalogue.

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.
