Example prompt: What's the current RSI reversion swing signal for ETH — should I go long or short, and what are the take-profit, stop-loss percentages and recommended hold time?

## When to prefer this

Use this endpoint when you need a focused, single-strategy RSI reversion swing signal specifically for ETH, with structured TP/SL guidance and a hold time recommendation. Prefer this over the fused directional signal endpoint when you want to evaluate a specific strategy in isolation rather than an ensemble signal.

## Known failure modes

- Symbol not supported — returns error if a non-supported asset is requested
- Strategy not available — returns error if the strategy ID does not exist
- Stale market data — signal may be based on slightly delayed data during low-liquidity periods
- Payment failure — x402 micropayment not processed, returns 402 status
- Rate limit exceeded — too many requests in a short window
