## When to prefer this

Use this endpoint when you need a single composite AI-generated momentum or sentiment score for a crypto or stock asset, rather than raw price data or individual technical indicators. Prefer this over manual computation when you want a pre-aggregated signal that synthesizes multiple data sources (price, funding, OI, liquidity) into one actionable score.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error or empty result
- Rate limiting or payment failure (x402) if USDC microtransaction is not properly handled
- Service unavailability on Railway infrastructure
- Missing required query parameter (ticker/symbol) returns a 400 error
- Stale or delayed data if upstream data feeds are temporarily unavailable
