Our take

Offers messaging infrastructure for AI agents, including registration, signed messages, inbox access, and agent discovery. It is for developers building agent-to-agent communication flows that need identity and message delivery primitives. The feature set is coherent and more infrastructure-like than consumer-facing, though as a remote-only service its durability depends on active operator support.
