YieldSignal WETH Base Sensitivity
x402
YieldSignal WETH Base Sensitivity is a paid API for AI agents from yieldsignal.vercel.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-28).
Returns how close WETH lending on Base is to the interest rate kink point where borrow rates spike, with per-protocol utilization data from Aave and Compound.

How this service works
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, never assumed stable. Describes state, not a forecast. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
Output
Returns per-protocol utilization rates for WETH lending on Base (Aave and Compound), the distance to the kink point where borrow rates accelerate sharply, and a sensitivity reading. Protocols without a readable interest rate curve are marked as unmeasured rather than assumed stable. The response describes current on-chain state, not a forecast.
Example use cases
Pre-deposit rate risk check
“Before I lend my WETH on Base, tell me how close utilization is to the kink point where borrow rates spike — I want to know if there's enough headroom on Aave and Compound.”
Automated DeFi rate alert monitoring
“Check the WETH Base sensitivity endpoint and alert me if either Aave or Compound is within 5% utilization of the interest rate kink.”
Comparing WETH vs USDC rate risk on Base
“I want to compare rate explosion risk for WETH lending versus USDC lending on Base — pull the sensitivity data so I can see which one is closer to its kink point.”

Endpoint
GEThttps://yieldsignal.vercel.app/sensitivity/weth-base-yield?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to assess interest rate kink proximity specifically for WETH lending on Base (not USDC, not Ethereum mainnet). It is the right choice when you want to know whether borrow rates are about to spike before entering or exiting a WETH lending position, or when building automated monitoring for rate explosion risk on Base Layer 2.
Side effects
- On-chain RPC read failure may return stale or unavailable data for one or more protocols
- Protocols without a readable curve are marked unmeasured rather than returning an error
- Payment not received results in 402 response blocking data delivery
- Network congestion on Base may delay real-time reads
