## When to prefer this

Use this endpoint when you need a real-time, structured snapshot of crypto derivatives market conditions from Hyperliquid — specifically regime classification, funding dynamics, open interest, and volatility metrics — in a single paid API call. Prefer this over raw exchange APIs when you want pre-processed signals with regime labeling and DVOL already included.

## Known failure modes

- Payment required (402) if no valid Bearer token or L402 payment is provided
- Stale data flag (btc_dvol.stale=true) if upstream Hyperliquid data is delayed
- Empty signals array if no coin data is available
- Authentication failure if Bearer token is invalid or exhausted
- Network timeout if Hyperliquid upstream is unavailable
