# Saylor Innovations ETH Staking Deposits

> Saylor Innovations ETH Staking Deposits is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Returns total ETH deposited and number of deposits sent to the Ethereum Beacon deposit contract, plus Lido stETH supply and its share of total deposits.

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 saylor-innovations-eth-staking-deposits-2c5ff3ab
```

Example prompt: Can you pull the latest Ethereum staking deposit stats — total ETH deposited to the Beacon contract, how many deposits have been made, and what share of that is Lido's stETH supply?

## When to prefer this

Use this endpoint when you need a combined snapshot of Ethereum Beacon chain deposit volume and Lido's liquid staking market share in a single call. It is preferable over raw on-chain RPC queries when you want pre-computed metrics like implied validator count and Lido's percentage share without writing contract-level code. Choose this over the sibling Lido-specific endpoint when you need both the aggregate Beacon deposit picture and the Lido context together.

## Known failure modes

- On-chain RPC unavailability may cause stale or missing data
- Lido stETH supply fields may return null if the Lido contract is unreachable
- Incorrect or malformed chain parameters could return an error response
- Network timeouts may occur during high congestion on Ethereum mainnet

## How this service works

Ethereum staking deposits: total ETH and number of deposits sent to the Beacon deposit contract, plus Lido stETH supply for scale.

## Output

A JSON object containing: chain name and EIP-155 chain ID, total number of deposits ever sent to the Beacon deposit contract, total ETH held by the deposit contract, the implied number of 32-ETH validator deposits, Lido stETH total supply in ETH (nullable), Lido's share of deposited ETH as a percentage (nullable), the data source, and a plain-language note summarizing the result.
