## 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-decision-24d4278a
```

Example prompt: Should I move my ETH liquid staking position or hold it? I'm currently staked with Lido — give me a MOVE or HOLD signal based on today's risk-weighted yields across Ethereum mainnet staking protocols.

## When to prefer this

Use this endpoint when an agent or user needs a binary buy-side MOVE/HOLD signal for ETH liquid staking on Ethereum mainnet specifically, rather than raw APY data alone. Prefer this over the sibling APY-only endpoints when you need a decision recommendation rather than numeric yield data. Choose this over generic DeFi yield aggregators when you want a pre-computed, risk-adjusted, on-chain-attested signal with verifiable accuracy.

## Known failure modes

- On-chain RPC unavailability may cause stale or failed yield reads
- Payment not completed or invalid x402 payment header returns 402 error
- Rate limiting or network errors from the Vercel deployment returning 503
- Protocol data source outage causing incomplete APY comparison

## How this service works

## Output

A MOVE or HOLD decision signal for ETH liquid staking on Ethereum mainnet, informed by real-time risk-weighted APY data aggregated from protocols such as Lido, Rocket Pool, and Coinbase Wrapped ETH. The response indicates whether a buyer should reposition their staking allocation or remain in their current position.
