How Long A Weth Leadership Call Actually Holds API
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.
