The canonical position for AI-native software protocol — the rules governing how software systems communicate and interoperate.

A foundational coordinate for the protocol layer of software — the standards, conventions, and communication rules that allow software systems, agents, and services to interoperate reliably.

Why this is canonical

'Software protocol' designates the governing rules of software interoperability — from network protocols (TCP/IP, HTTP) to application-layer conventions (REST, GraphQL, gRPC) and, increasingly, AI-agent communication protocols. On .ai, the string positions at the precise moment when new protocols are being written to govern how AI systems communicate, delegate tasks, and share state — a foundational infrastructure question for the agentic era.

Where it fits

A few directions this coordinate opens —

AI agent communication standards
The namespace for the emerging protocols governing how AI agents communicate, delegate, and interoperate across systems and organizations.
Agent-framework builders, AI-infrastructure companies
API and integration standards
A neutral coordinate for the protocol layer of software integration — REST, GraphQL, gRPC, and their AI-era successors.
API-tooling companies, integration platforms, standards bodies

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