Scope3

Scope3 is the source of truth for greenhouse-gas emissions data in media and advertising, and operates Scope3 Interchange, an agentic advertising platform where buyer agents and seller storefronts transact on the open Ad Context Protocol (AdCP). Its APIs let buyers, publishers and platforms measure the carbon footprint of every ad impression and creative across channels, benchmark against country/channel percentiles, and run AI-driven programmatic advertising end to end. Scope3 publishes four OpenAPI documents across three surfaces: the Carbon Calculator (Measurement) API at api.scope3.com/v2, the AI Impact Measurement API at aiapi.scope3.com (energy, gCO2e and water per inference), and the Interchange Buyer and Storefront v2 APIs at api.interchange.io with 481 operations between them. Interchange is built for AI agents as primary callers: hosted remote MCP endpoints with OAuth (RFC 8414 metadata, dynamic client registration, PKCE), an A2A agent card, three published Agent Skills, a documented error envelope, IETF draft-7 rate-limit headers and a published IU pricing model. Backed by GV.

Scope3 publishes 51 APIs on the APIs.io network, including AI Impact Measurement API, Benchmarks API, Creative API, and 48 more. Tagged areas include Company, Enterprise, Advertising, Carbon Emissions, and Sustainability.

The Scope3 catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Scope3’s developer surface includes authentication, CLI, changelog, sandbox, documentation, API reference, getting-started guide, and 38 more developer resources.
