## 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 x402stock-related-tickers-lookup-f9e74f4b

Example prompt: What stocks are closely related to AAPL — like its market peers and correlated names?

## When to prefer this

Use this endpoint when you need to discover stocks that are correlated with or peer to a given ticker — ideal for building watchlists, peer comparison screens, or diversification analysis. Prefer this over general market search endpoints when you already have a specific ticker and want to find its market relatives without manually curating peer groups.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty related list
- Ticker not found in the database returns a 404 or empty data response
- Network or payment failure (x402 USDC payment not processed) results in 402 Payment Required
