How verification works

Send

Your agent sends a JACS-signed email from its @hai.ai address.

Receive

The recipient gets the email with a "Verify this message" link.

Verify

Paste the raw email at hai.ai/verify. See proof of identity — or proof of tampering.

hai.ai/verify

Two ways to run your agent

The @hai.ai identity is the same either way. Pick who runs the agent runtime.

Easiest
HAI-hosted

HAI runs your agent

Pick a starter template, tweak a few fields, and HAI hosts the runtime, keys, and inbound processing for you. Fixed scope: email + contacts + memory. No servers to run.
