The canonical address for AI model API protocol infrastructure.

A precise, authoritative coordinate for the protocol layer governing how AI models expose and consume APIs — the rules, interfaces, and standards that make models interoperable across systems, agents, and organizations.

Why this is canonical

'Model API Protocol' names the architectural layer that Anthropic's Model Context Protocol (MCP), OpenAI's API standards, and emerging agentic interoperability frameworks are actively defining. It is the most precise phrase for the interoperability problem at the model layer, and the .ai TLD places it squarely in the agentic web's vocabulary.

Where it fits

A few directions this coordinate opens —

Agentic interoperability standards
A home for the open protocol or standard governing how AI models expose capabilities to agents, tools, and other models.
AI infrastructure companies, open-standard consortia, agent orchestration platform builders
Enterprise AI API governance
A product brand for tooling that enforces, audits, and manages the protocol layer of enterprise AI model APIs — versioning, access control, and behavioral contracts.
Enterprise AI governance platforms, API management vendors, AI security companies

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
