## 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`):

Example prompt: What's the current on-chain price and liquidity for tokenized NVDA on Robinhood Chain, and is it trading at a premium or discount to the real share price?

## When to prefer this

Use this endpoint when an agent needs real-time price, liquidity, or volume data specifically for tokenized equities on Robinhood's L2 blockchain, especially for 24/7 trading workflows where traditional market hours don't apply. Prefer this over generic DEX price endpoints when the asset is a tokenized stock or ETF and scam-token filtering is important.
