# Solend / Save Solana Lending API
> Live lending-market data from Solend (now Save), the leading Solana money market, over its public API — no key, nothing stored. This is the Solana lending view: every asset in the main pool with its supply and borrow APY, utilisation, value supplied and value borrowed, distinct from the other DeFi, DEX and lending APIs in the catalogue — Solend is an on-chain money market on Solana. The markets endpoint lists every asset with its live rates, utilisation and TVL, ranked by value supplied. The asset endpoint returns one asset by its symbol — its supply and borrow APY, utilisation, oracle price and the dollar value supplied and borrowed. The summary endpoint aggregates the pool: total value supplied and borrowed, asset count, the overall utilisation and the largest markets. Build DeFi lending dashboards, yield comparators, borrow-rate monitors and risk tools on top of real Solend data. Rates are live supply/borrow APYs and USD values are derived from on-chain reserve amounts and oracle prices; look up an asset by symbol (SOL, USDC).
