Climatiq

Climatiq API

The Climatiq API is a single REST surface at api.climatiq.io that groups search, estimation, and reference operations under a shared API-key (Bearer) auth model. It exposes /data/v1/search for discovering emission factors; /data/v1/estimate for activity-based estimation; family endpoints under /travel, /freight, /energy, /compute, /procurement, /autopilot, /classifications, and /cbam for purpose-built calculations; and reference endpoints for regions and unit types. All endpoints return CO2e in kilograms together with the underlying factor and gas breakdown.
