Daily total value locked history for one chain or for all of DeFi, up to ten years of points, with latest, first, minimum, maximum and mean and the change over the window. Use it when an agent is charting a chain's growth or checking whether a TVL move is new or a return to trend.

DeFi lending rates vs Treasury yields: USDC supply and borrow APR on Aave v3 across five chains, read on chain, against the 3-month T-bill, with the spread and what it says about on-chain leverage demand. Use to compare DeFi and TradFi dollar yields.

Collateralized DeFi loan (Aave/Compound style): health factor, current LTV, collateral liquidation price, drop it can withstand, extra borrowing room and how much to repay or add to reach a 1.5 health factor.

Protocols ranked by fees paid by users or by revenue kept, with 24h, 7d, 30d, 1y and all-time totals, change, category and chains, and chain-level gas fees on request. Use it when an agent is comparing protocols on real usage rather than TVL or valuing a token against the fees its protocol earns.

Top DeFi protocols ranked by total value locked (TVL) — name, category, chains, 1d/7d TVL change, and mcap/TVL ratio as JSON. Filterable by chain and category. Use for: DeFi market share, protocol comparison, TVL rankings, ecosystem research. $0.001 USDC per call.

Look up the current Total Value Locked (TVL) for a DeFi protocol from an open DeFi analytics API. Identify the protocol by its slug (uniswap, aave, lido, ethena, etc.). Returns the total TVL plus per-chain breakdown and 24h/7d/30d change where the source exposes it.

Every DefiLlama protocol with current TVL, filtered server-side (the raw index is 8.5MB). Query: chain, category (Lending, Dexes, ...), min_tvl (USD), sort (tvl|change_1d|change_7d), limit (1-100). Each: name, slug, chain, category, tvl_usd, change_1d, change_7d, mcap. Use the slug with /llama/tvl for a live single-number poll.
