Capabilities / Emission-factor lookup
The factor endpoint returns the underlying emission factor — value, unit, methodology, source, licence, data year, gas basis and GWP version — without performing a calculation. Look up by factor id, activity type, BEA code, or spend classification (MCC / NAICS / ISIC / SIC / NACE) for audit-grade provenance.
