When to prefer

Choose this endpoint when you need transparent, rule-based crypto trading signals grounded in standard technical indicators (RSI, MACD, Bollinger Bands) plus real-time perpetual funding rates for BTC, ETH, or SOL — especially when you want auditable, non-black-box signal logic rather than opaque ML predictions.

Side effects

Unsupported asset symbol returns an error
Market data feed unavailable causes stale or null indicator values
Malformed POST body returns a 400 validation error
Micropayment not processed correctly returns a 402 Payment Required
Rate limiting may return 429 if called too frequently
