Pre-trade risk check for AI agents trading crypto: live orderbook slippage at YOUR size, side-aware funding carry, open-interest crowding, and optional contract security — composed into a single ok/caution/avoid verdict with per-factor reasons and raw data embedded. Answers 'is this trade sane?' before trading, not after. Replaces four API integrations plus the judgment layer.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
