## 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

Example prompt: Pull the daily Glassnode data on total ETH 2.0 validator count — I want to see how many unique addresses have deposited 32 ETH to the deposit contract, returned as JSON.

## When to prefer this

Use this endpoint when you need authoritative on-chain Glassnode data specifically about ETH 2.0 validator counts — the total cumulative number of unique addresses depositing 32 ETH to the beacon chain deposit contract. Prefer this over generic staking dashboards when you need programmatic, time-series access to this metric for analysis, monitoring, or integration into dashboards.

## Known failure modes

- Invalid format parameter 'f' (must be 'json' or 'csv') returns 400 error
- Insufficient USDC balance or x402 payment failure returns 402 Payment Required
- Rate limiting or provider downtime returns 429 or 503
