## 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 stablejack-onchain-user-activity-d2867841 -d '<json body>'
```

Example prompt: Pull the onchain user activity proxy for Ethereum from StableJack — I want to see how active the network is right now across a broad scope.

## When to prefer this

Choose this endpoint when you need a quick, agent-ready derived proxy for onchain user activity on a specific blockchain or DeFi protocol, especially when you want a synthesized signal rather than raw transaction counts. Prefer it over generic blockchain explorers when you need a pre-computed activity metric suitable for downstream agent reasoning or automated workflows.

## Known failure modes

- Invalid or unrecognized protocol slug returns an error
- Missing required scope parameter causes request failure
- Unsupported chain or protocol returns no data
- API returns stale or delayed data during high network load
- Payment of $0.05 USDC not fulfilled causes 402 rejection

## How this service works

Retrieve a derived chain or protocol activity proxy. Include scope and a canonical target such as Ethereum or a protocol slug.

## Output

Returns a derived proxy metric or score representing on-chain or protocol user activity for the specified chain or protocol, along with scope context and relevant signals indicating network or protocol engagement levels.
