Decide the OCEAN SOURCING STRATEGY for a lane over a YEAR — lock an annual/quarterly CONTRACT rate, stay on SPOT, or SPLIT — and in what proportion. This is the procurement/CFO decision the other tools don't touch: not 'book this box now' but 'how do I source my whole volume?'. It costs THREE strategies over your expected annual volume: 100% SPOT, 100% CONTRACT, and the OPTIMAL MIX. The spot side is a real DISTRIBUTION, not a mean: it builds a 52-week expected-spot path from our own forecast (Holt-Winters), the corridor's spot volatility and the seasonal calendar, so a peak-season spike shows up as a fat P95 TAIL. It reads the MARKET REGIME (soft / balanced / tight / extreme) — because the contract↔spot relationship FLIPS with the cycle: in a soft market a contract sits ABOVE cheap spot (you'd overpay), in a tight market spot spikes above contract (the contract PROTECTS you). It computes the BREAK-EVEN contract rate (where 100% contract beats expected 100% spot), optimizes the contract/spot MIX on a mean-variance objective for your risk tolerance (contract the steady base, leave the peak on spot), models MQC shortfall penalties (the cost of over-committing in a light year) and the loading-PRIORITY a contract buys (less peak rollover), and quantifies the VALUE OF PROTECTION in dollars. Honest by design (regla 7): the contract↔spot relationship is regime-dependent and uncertain, so contract rates are MODELED BANDS anchored to the lane's mid-cycle — NOT a filed carrier tariff. Pass your own offered contract rate to score it against break-even. PREMIUM: pay per call with x402 (USDC on Base) or set a prepaid key (FREIGHT_PULSE_KEY). Same UN/LOCODE port normalization as get_spot_rate.
