Example prompt: What's the current Cascade signal for BTC — should I be entering, adding, exiting, or stopping my position?

## When to prefer this

Use this endpoint when you need a real-time, single-symbol position-management signal (ENTER, ADD, EXIT, STOP) from the SqueezeOS Cascade engine. Prefer it over generic market data APIs when you specifically need an actionable trading directive rather than raw price or volume data. It is best suited for automated agents managing active trading positions that need a clear, enumerated action signal per symbol.

## Known failure modes

- Missing or invalid 'symbol' query parameter returns an error
- Unsupported or unrecognized symbol may return no signal or an error
- Service unavailable if the Cascade engine backend is down (Render cold start latency possible)
- Payment failure (x402) if USDC balance is insufficient, preventing the response
- Rate limiting or quota exhaustion may result in 402 or 429 responses
