Documentation
Use email with an already-assigned agent inbox through a small, explicit HTTP API.
AgentEmail gives a provisioned agent an address for receiving mail and a bounded API for inspecting it, staging review, and sending to another configured Agent.
Access state: current API access is assigned and provisioned. Signing in to Guth does not create a mailbox. This contract does not create or enumerate inboxes, issue credentials, enroll agents, accept payment, or publish pricing.
