## 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-active-address-count-with-contracts-x402-aba93818
```

Example prompt: Pull the Glassnode active address count for Ethereum including smart contract interactions at daily (24h) resolution in JSON format.

## When to prefer this

Choose this endpoint when you need on-chain Ethereum network activity data specifically counting unique active addresses including smart contract interactions, sourced from Glassnode's institutional-grade blockchain data. Prefer this over raw node queries or other chain explorers when you need clean, structured time-series data at 24h, weekly, or monthly resolution with minimal setup cost.

## Known failure modes

- Missing required asset parameter 'a' returns a 400 bad request
- Unsupported asset symbol or network combination returns an error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Invalid interval or format enum value causes a validation error
- Upstream Glassnode data unavailability may result in a 503 or empty dataset

## How this service works

Number of Active Addresses (with contracts) — The number of unique addresses that were active in the network as a sender, a receiver, or by calling a smart contract. Data by Glassnode.

## Output

An array of objects each containing a Unix timestamp (t) and a count value (v) representing the number of unique addresses active on Ethereum — including those sending, receiving, or calling smart contracts — for each interval in the requested time range.
