Climatiq provides a developer-first API for carbon accounting and emissions calculations. The platform packages a curated emission-factor database together with calculation endpoints that turn activity or spend data into auditable CO2-equivalent estimates aligned with the GHG Protocol. Capabilities span search across the factor catalog, generic activity-based estimation, and purpose-built endpoints for travel, freight (GLEC), energy, cloud computing, procurement, and the EU Carbon Border Adjustment Mechanism. The API is keyed (Bearer token) and hosted at api.climatiq.io.

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.
