• POST /api/v1/freight — Freight carbon: CO2e for road/rail/sea/air shipments by weight × distance, single-leg or multi-leg intermodal. Ports/airports by UN-LOCODE, IATA, name or lat/long. (0.003 USDC on Base)
• GET /api/v1/factor — Emission-factor lookup: fetch the underlying factor (value, unit, methodology, source, licence) by id, activity_type, BEA code, or spend classification. Audit-grade provenance, no calculation. (0.003 USDC on Base)
• POST /api/v1/cbam/batch — Batch EU CBAM: liability for a portfolio of shipments in one call (1–100 shipments; a single live ETS price is shared). Priced per shipment. (0.016 USDC on Base)
• POST /api/v1/transaction — Spend-based carbon (Scope 3): convert a transaction amount + industry code (MCC/NAICS/BEA/ISIC/SIC/NACE) into verified CO2e. 200+ countries, licensed emission factors with full provenance. (0.003 USDC on Base)
• POST /api/v1/flight — Flight carbon: great-circle CO2e for a route by IATA/UN-LOCODE or lat/long, by cabin class and passengers, with optional radiative forcing (BEIS 2025 factors). (0.003 USDC on Base)
• POST /api/v1/activity/batch — Batch activity-based carbon: many activity calculations in one call (1–100 items). Priced per item. (0.006 USDC on Base)
