## 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-address-count-metric-33d453ca
```

Example prompt: Pull the Glassnode total unique address count for BTC on a daily (24h) interval and return it as JSON so I can track network adoption over time.

## When to prefer this

Use this endpoint when you need cumulative unique address count data from Glassnode for a specific cryptocurrency (BTC, ETH, SOL, etc.) with flexible time resolution and network granularity. Prefer this over general blockchain explorers when you need structured time-series data suitable for trend analysis or charting.

## Known failure modes

- Missing required asset symbol 'a' parameter returns a 400 or error response
- Unsupported asset symbol returns an error or empty dataset
- Unsupported network for the given asset returns an error
- Payment not included or insufficient triggers a 402 Payment Required response
- Invalid interval or format enum value returns a validation error

## How this service works

Number of Addresses — The total number of unique addresses that ever appeared in a transaction of the native coin in the network. Data by Glassnode.

## Output

Returns a time series array of objects, each containing a Unix timestamp ('t') and the cumulative count of unique addresses ('v') that have ever appeared in a transaction on the network, at the requested resolution (24h, 1w, or 1month).
