## 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 messari-x-users-social-signal-rankings-f0119b79
```

Example prompt: Show me the top 20 crypto influencers on X right now from Messari's signal rankings — include their mindshare scores, sentiment, and follower counts. Search for accounts related to 'DeFi'.

## When to prefer this

Use this endpoint when you need a broad ranked view of influential crypto X users with mindshare and sentiment context, rather than deep-diving into a single user's profile. Prefer this over the single-user profile endpoint when you want to discover or compare multiple accounts, or when searching for influencers by keyword. Best suited for building leaderboards, identifying trending voices, or filtering the crypto influencer landscape by name.
