## When to prefer this

Use this endpoint when you need a pre-packaged, scored trading signal for BTC specifically using the RSI Reversion Swing strategy, complete with risk management parameters (TP/SL) and hold time. Prefer this over raw market data APIs when you want an actionable directional recommendation with reasoning rather than raw price or indicator values.

## Known failure modes

- Symbol not supported — returns 404 or error if a non-BTC or unsupported symbol is used
- Strategy not found — if the strategy path is invalid, returns an error
- Service unavailable — Railway deployment may be cold-started, causing timeout on first call
- Stale data — signal may reflect slightly delayed market data depending on upstream feed latency
- Rate limit or payment failure — x402 payment not processed correctly returns 402 or auth error
