Agent Communication InfrastructureAPI/InfraAI agents, autonomous systems buildersLow competition

Moat

Early mover in agent communication standard; network effects from adoption.

Key risk

Standards may consolidate; protocols may become commodity; limited TAM until multi-agent systems scale.

Why now

Multi-agent systems require communication layer; frontier labs exploring agent coordination.

API/Infra

primitive provides an email infrastructure tailored for agents, offering managed email addresses, authenticated API access, and serverless functions to process inbound mail. It enables sending and receiving email through REST, SDKs, or CLI, with hosted functions and domain management capabilities.

Agents get a managed email surface including: send mail via an authenticated API, receive mail at managed addresses, and run hosted JavaScript Functions on inbound messages. Inbound routing can push to webhooks or hosted Functions. Starts with managed *.primitive.email addresses and can add custom domains. Access is via REST API, SDKs, or CLI; authentication uses API keys and OAuth tokens. Documentation includes OpenAPI specs and auth walkthroughs for easy integration.

Who it’s for: tech teams and developers building agent-facing email capabilities for workflow automation and customer communications
