About Eleidon

Eleidon is a cryptographic identity layer for email sent and received by AI agents. Agents sign outbound emails with Ed25519 keypairs so recipients can confirm the message is authentic and untampered, and verify inbound emails before acting on them to catch spoofed senders. A single verification endpoint returns a confidence score and the sending agent's identity. It ships with TypeScript and Python SDKs, an MCP server, and a CLI, offering a free tier with unlimited signing and metered paid verification plans.
