## 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-gini-coefficient-x402-1f578578
```

Example prompt: What's the current Gini coefficient for Bitcoin from Glassnode — pull the daily 24h data in JSON format so I can see how equally BTC is distributed across addresses right now?

## When to prefer this

Use this endpoint when you need a quantitative, time-series measure of wealth concentration across blockchain addresses for Bitcoin or Ethereum. It is the standard econometric Gini inequality statistic applied to on-chain data, making it ideal for comparing distribution fairness over time or across assets. Prefer this over other on-chain metrics when the specific question is about address-level wealth equality or inequality trends.

## Known failure modes

- Missing required asset symbol 'a' returns a 400 validation error
- Unsupported asset symbol returns a 404 or empty result
- Invalid interval or format enum value returns a 400 error
- Payment not included or insufficient USDC results in 402 Payment Required
- Rate limiting may return a 429 Too Many Requests
- Network or upstream Glassnode data unavailability returns a 503

## How this service works

Gini Coefficient — Gini Coefficient is the classical inequality statistic applied to the distribution of coins over addresses. Data by Glassnode.

## Output

A JSON (or CSV) array of objects, each containing a UNIX timestamp (t) and a scalar Gini coefficient value (v) between 0 and 1 representing wealth inequality across addresses for the requested asset — higher values indicate more concentrated holdings
