Example prompt: What tickers are most closely related to NVDA based on news and analyst co-occurrence? I want to build a quick peer set for comparison.

## When to prefer this

Use this endpoint when you need a fast, data-driven peer set for a US-listed stock without manually curating a competitor list — particularly useful for comparative valuation, watchlist construction, or identifying analyst coverage clusters. Prefer this over manually searching news or financial databases when you need a programmatic, structured list of co-occurring tickers. Best for US-listed equities where news and analyst co-occurrence data is rich.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty related list
- Ticker not covered by co-occurrence data returns zero results
- Payment failure via x402 protocol blocks the request
- Delisted or OTC tickers may not be supported
- Rate or network issues may cause timeouts
