## 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 hoodgrow-markets-overview-2baca241
```

Example prompt: What are the top gaining and losing tokenized stocks on Robinhood Chain right now, and which ones have the highest swap volume and deepest Uniswap V3 liquidity?

## When to prefer this

Use this endpoint when you need a broad, ranked market overview of all Robinhood Chain tokenized stock tokens at once — covering gainers, losers, volume leaders, and TVL leaders in a single call. Prefer it over per-token endpoints when you don't know which specific ticker to query and want to discover market leaders or scan for opportunities across the entire catalog.

## Known failure modes

- Payment required (402): x402 micropayment of $0.05 USDC not provided or rejected
- Data staleness: on-chain data may lag by one block or indexing delay
- Empty results: if no markets are active or indexed yet
- Rate limiting: too many calls in quick succession may be throttled
