## When to prefer this

Use this endpoint when you need to discover peer or related stocks for a given ticker symbol, such as for building comparison screens, sector groupings, or correlation analysis. Prefer this over a general ticker search when you already have a specific symbol and want to find associated equities.

## Known failure modes

- Unknown or invalid ticker symbol returns empty related array or error
- Ticker not covered by the Massive data source returns no results
- Network or payment (x402) failure results in no response
- Rate limiting or insufficient USDC balance prevents call

## How this service works

Tickers related to the given symbol based on news and analyst coverage co-occurrence, a quick peer set for comparative analysis. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

## Output

Returns a JSON object with a ticker field (the queried symbol), a data object containing a count (number of related tickers) and a related array of ticker symbol strings, a source field indicating the data provider (Massive), and an as_of timestamp.
