Making an email API agent-native: llms.txt, a /api/me endpoint, and a zero-DNS sandbox sender
31+ min ago (454+ words) Most APIs are "agent-compatible": an agent can call them. Far fewer are agent-native: an agent can accomplish the whole job on its own, with no human un-sticking it halfway. We spent a few weeks turning Send16 (an email platform) from the…...
