Calculate CBAM liability for up to 100 shipments in one request and return a portfolio-level summary (total embedded tCO2e, total certificates, total EUR liability). Ideal for pricing a whole shipment manifest or product catalogue. Per-item ok/not_covered/error — one bad item doesn't fail the batch. Each shipment supports actual_emissions_tco2e_per_t and carbon_price_paid_eur_per_tonne.
