Greenspark is an Impact-as-a-Service platform that lets businesses embed climate and environmental action into their products and customer journeys. Its Climate API programmatically funds verified impacts — carbon offset, tree planting, ocean-plastic recovery, kelp restoration, clean water and bee protection — and provides carbon-footprint estimation (by Merchant Category Code or Open Banking category), impact reporting, email/notification templates, and embeddable impact widgets for storefronts. Authentication is a single x-api-key header with separate sandbox, demo and production environments. Greenspark ships six first-party TypeScript SDKs, a ReadMe-hosted MCP server, and packaged Agent Skills. Backed by Anthemis; profiled and enriched by the API Evangelist network.
