Exit capacity for USDC lending on Base: per-protocol utilization and withdrawable liquidity read from the protocol's own books (Aave, Compound), plus whether your size (?amountUsd=) can be withdrawn r…
Exit capacity for WETH lending on Base — same contract as the USDC capacity route. Utilization is reported for every measured protocol; USD figures are omitted for WETH (no price oracle in the paid pa…
Buyer-side MOVE/HOLD decision for ETH liquid staking (Ethereum mainnet) — same contract as the lending decision routes, for ETH staking. Verified per-asset accuracy is free at /accuracy.json; raw on-c…
Buyer-side MOVE/HOLD decision for USDC lending on Base: given your position (?position=), size (?amountUsd=), move cost (?moveCostUsd=) and horizon (?horizonDays=), returns whether moving to the best …

How much of the USDC lending APY on Base survives if incentives stop: per-protocol base-vs-reward split, the post-incentive floor, and whether the leader changes without incentives. Derived only from …
How much of the WETH lending APY on Base survives if incentives stop — same contract as the USDC durability route, for WETH. Undecomposable sources are named, never assumed incentive-free. Stress test…
Shared risk exposure across declared positions: pass ?positions=aave:200000,morpho:150000 and get, per factor, how much capital sits behind the same collateral, oracle or curator, and via which venues…
Shared risk exposure across declared WETH positions — same contract as the USDC exposure route. Pass ?positions=aave:100000,morpho:50000. Protocols whose collateral composition cannot be established a…
How long an ETH liquid staking leadership call actually holds — same contract as the lending persistence routes. Median lead duration, survival at 6/24/72h, and the round-trip share of leader rotation…
How long a USDC leadership call actually holds, from hourly on-chain attestations (EAS): median lead duration, survival at 6/24/72h, how much of the rotation is the same two protocols trading places, …
How long a WETH leadership call actually holds — same contract as the USDC persistence route. Where the lead has not changed in the observed window, the duration is reported as a floor with a censorin…
How close USDC lending on Base is to the kink where borrow rates explode: per-protocol utilization, the kink read from the protocol's own rate curve, headroom in bps, and borrow APY at points around i…
How close WETH lending on Base is to the kink where borrow rates explode — same contract as the USDC sensitivity route. Aave and Compound only; protocols without a readable curve are marked unmeasured…
