## 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 saylor-innovations-data-desk-liquid-staking-apy-comparison-28858a9e
```

Example prompt: Can you pull the latest liquid staking APY comparison for Marinade mSOL, Jito JitoSOL, and Rocket Pool rETH — including TVL and validator counts — and tell me which one has the highest yield right now?

## When to prefer this

Choose this endpoint when you need a single consolidated lookup of liquid staking yields across Marinade mSOL (Solana), Jito JitoSOL (Solana), and Rocket Pool rETH (Ethereum) with protocol metadata like TVL and validators in one call, rather than hitting each protocol's own API separately.

## Known failure modes

- Upstream staking protocol data unavailable causing stale or missing APY values
- Payment not processed resulting in 402 response
- Rate limiting or provider downtime returning 5xx error
- Partial data if one protocol (e.g. Rocket Pool) is temporarily unreachable

## How this service works

Liquid staking yields compared - Marinade mSOL, Jito JitoSOL and Rocket Pool rETH APY with protocol details such as TVL, validators and beacon chain APR

## Output

A JSON object containing an array of yield records, each with asset name, chain, protocol, APY percent, averaging window, and as-of date, plus a count of items, the asset with the highest APY, a data source attribution, and an optional contextual note.
