  title: Climatiq Autopilot Computing API
  version: '3'
  description: Climatiq is a carbon emissions calculation API that gives developers programmatic access to a curated database of emission factors and to purpose-built calculation endpoints. The API exposes search over the factor catalog and a family of estimation endpoints for activity-based and spend-based calculations across travel, freight, energy, cloud computing, procurement, and CBAM workflows. Authentication uses an API key sent as a Bearer token in the Authorization header. Responses are JSON with deterministic emission outputs in CO2e (kg) plus the underlying factor metadata.
