How this service works
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 path), so size verdicts need the USDC route. Unmeasured protocols are named, never assumed liquid. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
Output
Returns per-protocol utilization percentages and withdrawable WETH liquidity figures for each measured protocol on Base. Unmeasured protocols are listed by name without assumed liquidity. If amountUsd is provided, includes a size verdict on whether the exit is feasible. USD figures are not included (no price oracle); use the USDC capacity route for USD-denominated size verdicts.
Example use cases
Pre-exit liquidity check for large WETH position
“I'm about to withdraw $300,000 worth of WETH from lending on Base — can you tell me if the exit capacity is there and which protocols are most liquid right now?”
Monitoring WETH market utilization on Base
“What's the current utilization rate across all WETH lending protocols on Base? I want to know how close each one is to the rate kink.”
Comparing available WETH exit liquidity across protocols
“Show me the free withdrawable WETH liquidity on Base across Aave, Morpho, and Compound — I want to know which protocol has the most room to exit without slippage.”
Technical details
Endpoint
GEThttps://yieldsignal.vercel.app/capacity/weth-base-yield?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time exit capacity and utilization data specifically for WETH lending on Base. Prefer this over the USDC capacity route when the asset in question is WETH. Note: because USD figures are omitted (no price oracle), if you need a dollar-denominated size verdict, pair this with the USDC capacity route. Use the /accuracy.json endpoint for free verification of per-asset accuracy before relying on the data for large position decisions.
Side effects
- Missing or unavailable on-chain data for a specific protocol — unmeasured protocols are named but not given liquidity figures
- amountUsd provided but no USD verdict returned because WETH price oracle is not available in the paid path
- Network or RPC issues causing stale or partial utilization data
- Invalid query parameter type for amountUsd (non-numeric)
- Payment failure or insufficient USDC balance for the $0.01 fee via x402
