Capabilities / EU CBAM liability
The CBAM endpoint calculates EU Carbon Border Adjustment Mechanism liability for an imported good. Send a CN code, country of origin and weight; it returns embedded emissions, the free-allocation benchmark, certificates required, and estimated EUR liability using the year's phase-in rate and the live EU ETS price — under EU default values or your verified MRV. Batch a portfolio via /v1/cbam/batch.
