Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability emblem-ecosystem-base-usdc-trading-leaderboard-44f00196 -d '<json body>'
```

## When to prefer this

Use this endpoint when you need ranked trading data specifically from the Emblem Vault ecosystem on the BASE_USDC market, with support for multi-metric sorting (volume, PnL, transactions, referrals, aura) and user search. Prefer this over generic on-chain analytics when you need Emblem-specific aura scores and referral tracking.
