DEVELOPER PLATFORM

Build on a Trusted API Foundation

Everything you need to integrate carbon accounting, deterministic emission calculations, and compliance reporting into your workflows.

01

Unified Carbon Data API

Submit operational activities, compute Scope 1, 2, and 3 emissions, and generate compliance-ready reports directly from a single REST API surface.

02

Official Node.js & Python SDKs

Ship quickly with typed official SDKs for Node.js (zerocarbon-nodejs-sdk) and Python, featuring automated retry logic and developer documentation.

03

Audit-Ready Compliance Reporting

Generate SEBI BRSR Core, GHG Protocol, and CDP-aligned reporting outputs with traceable calculation lineage and consistent schema validation.

04

Grid Factors & Emissions Monitoring

Access national grid Central Electricity Authority (CEA) emission factors, multi-facility tracking, and high-throughput calculations backed by a 99.9% uptime SLA.

REST & MCP SPECIFICATIONS

Production Endpoints & Protocol

Documented with OpenAPI 3.1, enforcing strict schema validation and generating verifiable execution hashes for statutory compliance.

ANTHROPIC & OPENAI MCP SPECIFICATION

Connect AI Coding Agents directly to ZeroCarbon

Run the ZeroCarbon MCP server inside Cursor, Claude Desktop, Windsurf, or Antigravity. Your LLM can inspect Scope 3 purchase orders, look up emissions factors, and verify ledger chains autonomously.
