## 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 market-data-related-peer-tickers-3cc07dc3
```

Example prompt: What are the peer and comparable tickers for NVDA — I want to see which stocks are grouped with it based on news and return correlations?

## When to prefer this

Use this endpoint when you need to identify comparable companies, build a peer basket, or find stocks that trade similarly to a reference ticker — especially useful for relative valuation, benchmarking, or portfolio construction workflows. Prefer over manual sector lookups when you want news- and returns-derived similarity rather than simple SIC/GICS classification.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Ticker not covered by the data provider returns no peers
- Network or payment authorization failure returns a 402 or 5xx error
- Rate limiting may cause transient failures

## How this service works

Related / peer tickers for a given ticker — comparables and peer baskets derived from news and returns.

## Output

A list of related/peer ticker symbols for the queried stock, representing the comparable basket derived from news co-occurrence and return-based similarity analysis.
