INTEGRATION · OPEN API

An API built for
teams that automate

The Kabaun API is built around a simple principle: every piece of carbon data must be accessible and modifiable programmatically. No usage limits, no proprietary format.

The base URL is unique : api.agkarb.kabaun.earth, with a Keycloak token auth managed automatically (refresh 60s before expiration).

  • Unified JSON format across all endpoints : success, data, errors
  • Multi-dimensional aggregates: scope, project, category, period
  • Bulk operations: create_many to import hundreds of activities
  • Native MCP: 42 tools to integrate directly with Claude or any AI agent

USE CASES · INTEGRATIONS

Who uses the Kabaun API?

From SI integrators to carbon data scientists, the API adapts to every technical context.

ERP / IS Integration
Connect your consumption flows (energy bills, purchases, travel) directly from SAP, Oracle or Sage to Kabaun without manual entry.
ERP · SAP · Oracle
Automated ESG reporting
Generate BEGES and CSRD reports programmatically. Schedule annual exports and feed your non-financial reporting tools.
CSRD · BEGES · GHG
AI Agents & MCP
Connect Claude or your own agent to the Kabaun MCP. The agent can query carbon inventories, suggest emission factors and create action plans.
MCP · Claude · AI Agents
BI Dashboards
Consume Kabaun aggregates in Tableau, Power BI or Looker. Visualize Scope 1/2/3 evolution in real time without manual export.
BI · Tableau · Power BI

COMPLIANCE · 4 STANDARDS

Your data, compliant by design

Each calculated impact is linked to a standard. The API exposes the reference framework used in every response.

GHG Protocol
International standard for greenhouse gas inventories. Scope 1, 2 and 3 categorized under the Corporate Standard.
Bilan Carbone®
ADEME reference method in France. Emission factors sourced directly from the official Base Carbone.
ISO 14064
International standard for quantification and reporting of GHG emissions at the organizational level.
CSRD / ESRS
ESRS E1 indicators automatically structured to feed your CSRD sustainability report.
