The compact protocol coordinate for agent-to-agent AI communication.

A2A is the architectural primitive — this is its natural namespace on the developer-facing TLD.

Coordinated sets this position belongs to — the coverage it extends. Counts are the live cluster size in the graph.

Why this is canonical

'A2A' (agent-to-agent) is the emerging shorthand for direct communication between AI agents without human intermediation — a fundamental architectural pattern in multi-agent systems. On .io, the developer-community TLD, this is the canonical compact address for the A2A protocol layer.

Where it fits

A few directions this coordinate opens —

A2A protocol implementation
A developer-facing home for an agent-to-agent communication protocol — the .io making it immediately legible as a technical project or open standard.
AI infrastructure builders, multi-agent framework developers
Agentic integration platform
A platform enabling AI agents from different vendors or systems to communicate and coordinate — the interoperability layer for the multi-agent era.
Enterprise AI platform builders, agent orchestration vendors

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