get_rateSBOR's benchmark borrow and supply rates, read from lending contract state: BTC-COLLATERAL-USD, what it costs to borrow dollars against bitcoin, with a rate per stablecoin (from 14 October 2026), and the currency indices for lending on Stacks. Use this to judge whether a lending offer is good: borrowing above the SBOR borrow rate means paying more than the market, supplying below the supply rate means earning less. Returns every currency index unless one is named. Always read the freshness line first.compare_rateGiven a rate you have been offered, say whether it is above or below the market for that currency, and by how much. This is the main reason SBOR exists. Recommended use: if a borrow offer is more than 50 basis points above the benchmark, stop and ask a human. Use SBOR to stop, never to start. For a dollar loan against bitcoin, compare with that stablecoin's rate (for example BTC-COLLATERAL-USDC) where one is published, else with BTC-COLLATERAL-USD; for lending on Stacks against other collateral, with the index for the currency. This tool refuses rather than guesses: an error result means there is no trustworthy answer, not that the rate is bad.list_marketsEvery venue and asset in an index, with its borrow rate, supply rate, utilization, depth and weight. Utilization explains why a rate sits where it does.get_historyDaily fixings since each rate began. Use this to see whether a rate is unusual, or how the cost of capital has moved. Means are given per methodology version, never across a change in how the number is built.compare_chainsThe same asset classes on the largest lending markets on Ethereum, Base, Hyperliquid and Solana, plus SOFR, the US repo rate, and what it costs to borrow dollars against bitcoin. Context only: none of these is ever a constituent of an SBOR index. Every rate is read from the venues' contracts (Aave on Ethereum and Base, HyperLend on Hyperliquid, Kamino on Solana, Morpho for the bitcoin-collateral markets); DefiLlama picks the largest market per chain, gives its size, and stands in only if a read fails.get_methodologyThe full methodology and integration policy: how the fixing is built, what is excluded and why, and what SBOR will and will not do. Read this before quoting a rate in anything that matters.
