## When to prefer this

Use this endpoint when you need a comprehensive snapshot of a stock's fundamental financial health in a single call — covering valuation, profitability, growth, and risk. Prefer this over price/OHLCV endpoints when the goal is investment analysis or screening rather than technical trading. Ideal for comparing stocks on fundamental criteria or evaluating whether a stock is overvalued/undervalued.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Metrics unavailable for OTC or thinly-traded stocks
- Data may be stale if underlying financial data provider hasn't updated recently
- Payment failure (402) if USDC balance is insufficient
- Rate limiting if too many requests are made in quick succession
