## 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 synthora-lido-steth-staking-apr-oracle-669ad44d -d '<json body>'
```

Example prompt: What is the current Lido stETH staking APR right now, and can you also give me the 7-day moving average and the daily breakdown so I can see if validator rewards have been drifting?

## When to prefer this

Choose this endpoint when an agent needs real-time Lido stETH APR data with smoothed 7-day SMA context for yield routing, rebalancing, or drift monitoring — particularly in autonomous DeFi agent pipelines that need a single call to get both spot and moving-average staking yield without scraping Lido directly.

## Known failure modes

- Lido eth-api upstream outage returns empty or error result object
- Invalid or missing keys/caller fields may cause authentication failure
- Stale data if Lido API has not refreshed recent validator epoch data
- Network timeout to hergertsynthora.com endpoint causing request failure
- Malformed payload parameter returning a 400-level error response

## How this service works

Returns live and moving-average Lido stETH staking APR (7-day SMA plus per-day breakdown) sourced from the official Lido eth-api. Feeds autonomous yield-optimizer agents, agent-to-agent liquid-staking rebalancers, and A2A DeFi strategies that route ETH into the highest-yield staking derivative and monitor validator reward drift. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

## Output

A JSON response containing a success flag, the service niche identifier ('lido-steth-staking-apr'), and a result object with the live stETH staking APR, 7-day simple moving average, and a per-day APR breakdown sourced from the official Lido eth-api
