YieldSignal WETH Base Yield Leadership Persistence
x402
YieldSignal WETH Base Yield Leadership Persistence is a paid API for AI agents from yieldsignal.vercel.app, paid per call via x402, $1/call, status unknown (last checked 2026-10-29).
Returns how long the current WETH lending yield leader on Base has held its top position, with censoring flags for unbroken leadership windows, based on observed on-chain history.

How this service works
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 censoring flag, never as a median. Observed history with sample sizes, never a forecast. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
Output
Returns the observed duration for which the current WETH lending yield leader on Base has held its position, expressed as a floor value with a censoring flag when leadership has not changed during the observation window. Includes sample sizes from the observed history. Does not forecast future leadership; purely historical and on-chain attested.
Example use cases
Evaluating WETH yield stability before allocating
“Before I move my WETH into a lending protocol on Base, can you check how long the current yield leader has actually held that top spot — I want to know if leadership is stable or flips around constantly.”
Automating rotation only on genuine leadership change
“I want my agent to only rotate my WETH lending position on Base when the yield leader actually changes — can you pull the leadership persistence data so we can see how often that really happens?”
Comparing WETH vs USDC yield leadership stability
“Pull the WETH lending leadership persistence on Base and tell me if the top protocol holds its lead longer for WETH than it does for USDC — I'm trying to figure out which asset has more predictable yield rankings.”

Endpoint
GEThttps://yieldsignal.vercel.app/persistence/weth-base-yield?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to assess the stability of WETH lending yield leadership on Base over observed historical windows, especially when distinguishing between genuinely long-held leadership (censored duration) versus frequent protocol turnover. Prefer this over raw APY endpoints when your decision logic depends on how reliable or persistent a yield ranking is, not just its current value. Complements the real-time WETH APY endpoint by adding a temporal stability dimension.
Side effects
- Payment not included or invalid — 402 response requiring x402 USDC payment
- Network congestion on Base causing stale or unavailable on-chain data
- Insufficient observation history for a statistically meaningful sample size — response may include very small sample sizes
- Service unavailability on Vercel hosting — 503 or timeout
