## When to prefer this

Choose this endpoint when you need a single comprehensive, decision-ready crypto market snapshot that spans spot, derivatives, on-chain, and macro dimensions — rather than querying multiple specialized APIs separately. Best for trading agents and financial advisors needing a holistic view at a point in time.

## Known failure modes

- Rate limit exceeded returns 429
- Transient market data gaps may yield partial brief with missing sub-sections

## How this service works

Institutional-grade, decision-ready crypto market brief — spot, derivatives (funding, options skew, DVOL), on-chain flows, regional premiums and macro-event odds. For trading and advisor agents.

## Output

A structured market brief containing spot price levels, derivatives data (funding rates, options skew, DVOL volatility index), on-chain flow metrics, regional exchange premiums, and probability estimates for upcoming macro events — formatted for immediate trading or advisory use.
