# YieldSignal ETH Liquid Staking Yield Persistence

> YieldSignal ETH Liquid Staking Yield 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 historical persistence statistics for ETH liquid staking yield leadership — median lead duration, survival rates at 6/24/72h, and leader rotation round-trip share — based on observed on-chain history.

## Facts

- Price: $1/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability yieldsignal-eth-liquid-staking-yield-persistence-6a024dad
```

Example prompt: How long does the top ETH liquid staking yield leader typically hold its position — can you pull the median lead duration, 6h/24h/72h survival rates, and rotation stats from YieldSignal's ETH staking persistence data?

## When to prefer this

Choose this endpoint when you need historical persistence and durability statistics for ETH liquid staking yield leadership — specifically survival rates and median lead duration — rather than real-time APY rankings or lending protocol data. Best used alongside the real-time ETH staking APY endpoint and the MOVE/HOLD decision endpoint for a complete yield strategy picture.

## Known failure modes

- Insufficient on-chain history for meaningful sample sizes — returns data with small sample size warnings
- Payment not received — 402 Payment Required response before data is returned
- Service unavailable — Vercel deployment downtime
- Stale data if on-chain indexing is delayed

## How this service works

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. 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 observed historical statistics for ETH liquid staking yield leadership including: median lead duration, survival probability at 6h/24h/72h horizons, round-trip share of leader rotation, and sample sizes. Data is based on on-chain history and never a forecast. Accuracy data available at /accuracy.json and raw on-chain attestations at /track-record.
