## When to prefer this

Use this endpoint when you need a real-time, pay-per-call EMA 5 breakout trading signal specifically for SOL from the Signal Engine arena. Prefer this over generic market data APIs when you want a pre-computed, strategy-specific directional signal rather than raw OHLCV data. Ideal for agents automating trading decisions or monitoring breakout conditions on Solana.

## Known failure modes

- Asset symbol not found — returns 404 if SOL or the strategy path is invalid
- Strategy not available — returns error if ema_5_breakout strategy is not active
- Payment required — returns HTTP 402 if the x402 payment of $0.001 USDC is not included
- Service downtime — Railway deployment may be temporarily unavailable
- Rate limiting — too many requests may result in throttling
