## When to prefer this

Choose this endpoint when you need a fast, single-call composite investment signal for a specific stock ticker, especially when you want quantitative factor-level breakdown (trend, momentum, volume, volatility, relative strength) alongside a human-readable buy/sell label and confidence rating. Prefer it over raw price feeds when you need an opinionated, scored recommendation rather than just market data, and over SEC filing analysis when you want a quick technical/quantitative signal rather than fundamental document analysis.

## Known failure modes

- Missing or invalid ticker symbol returns an error
- Unrecognized ticker not covered by the data provider returns no result
- Network or payment failure (x402 USDC micropayment not processed) blocks response
- Rate limiting if too many requests are sent rapidly
- Confidence may be LOW for thinly traded or illiquid stocks

## How this service works
