# Glassnode ETH Stake Effectiveness Mean

> Glassnode ETH Stake Effectiveness Mean is a paid API for AI agents from x402.glassnode.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns the daily mean Stake Effectiveness ratio for Ethereum — the proportion of staked ETH actively participating in consensus (Effective Balance / Total Staked Balance).

## 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 glassnode-eth-stake-effectiveness-mean-8a40c75a
```

Example prompt: Pull the latest Glassnode stake effectiveness data for ETH in JSON format so I can see what proportion of staked ETH is actively participating in consensus.

## When to prefer this

Use this endpoint when you need on-chain Ethereum validator participation quality data — specifically the ratio of effective balance to total staked balance. Prefer this over raw staking volume metrics when you want to assess consensus health, validator activation lag, or PoS network participation efficiency as computed by Glassnode.

## Known failure modes

- Missing required 'a=ETH' query parameter returns a 400 Bad Request
- Invalid format value for 'f' parameter returns an error
- Payment not included or insufficient USDC results in 402 Payment Required
- Network timeouts if Glassnode data pipeline is delayed
- Rate limiting if too many requests are sent in rapid succession

## How this service works

Stake Effectiveness — Stake Effectiveness is the proportion of staked ETH actively participating in consensus, computed as the ratio of Total Effective Balance to Total Staked Balance of the Proof-of-Stake validator set. Data by Glassnode.

## Output

Returns a JSON (or CSV) array of timestamped data points, each containing a Unix timestamp ('t') and a float value ('v') representing the mean Stake Effectiveness ratio for that 24-hour period — the ratio of Total Effective Balance to Total Staked Balance across all Ethereum PoS validators.
