Example prompt: What's the current Carbon & Cashmere market intelligence bundle for SOL — give me the price, ML signal direction and confidence, market regime, fear/greed reading, and overall market score.

## When to prefer this

Use this endpoint when you need a comprehensive, pre-packaged intelligence bundle for SOL specifically, combining price, ML signals, regime detection, and sentiment in a single call rather than assembling from multiple sources. Prefer this over raw exchange APIs when you want scored, interpreted signals rather than raw tick data.

## Known failure modes

- Invalid coin symbol returns 404 or empty response
- Payment not included or invalid x402 payment header returns 402 Payment Required
- Downstream data source unavailable causes 503 or stale data
- Rate limiting may return 429 if called too frequently
- ML model may return low-confidence signals during low-liquidity periods
